Welcome to the flow control specialization center at THS Now. In any piping configuration, pipes serve as the pathways, but valves act as the decision-makers — they control, direct, isolate, and regulate the flow of liquids and gases throughout your system. A faulty or poorly specified valve compromises system safety, leading to pressure drops, leaks, or backflow. Whether you're looking for a water ball valve for a home plumbing line, a full bore ball valve for an industrial process, an industrial ball valve for a commercial installation, or simply need a reliable ball valve shut off point for maintenance, THS Now's collection offers precision-engineered valves for residential, commercial, and industrial use — built for leak-free operation, minimal friction loss, and long service life.
How to Choose the Correct Valve for Flow Management
Selecting the right valve goes beyond matching pipe sizes. Installing a valve unsuited to your application causes internal turbulence, premature seal wear, and mechanical failure. Three engineering rules guide the right choice:
1. On/Off Shut-Off vs. Throttling Control
Valves are built for distinct mechanical jobs. If your goal is pure isolation — a clean ball valve shut off that fully opens or fully closes a line instantly — a quarter-turn ball valve is the right tool. Ball valves should never be left half-open to regulate flow volume, since the high-velocity stream at a partial opening erodes the internal seat quickly. For fine, incremental throttling control instead, a globe valve or needle valve is built to handle mid-position fluid stress without that wear.
2. Material Durability — Brass, PVC, Stainless Steel
The fluid's chemistry and temperature determine what body material your valve needs:
-
Forged brass: The standard for domestic plumbing and most water ball valve applications: strong, easy to thread, and resistant to mineral scaling in hot and cold water lines.
-
UPVC/PVC/CPVC: Economical, lightweight, and immune to electrochemical corrosion. Common for water treatment lines, cold-water irrigation, and low-pressure residential systems.
-
Stainless steel (SS304/SS316): The standard body material for a demanding industrial ball valve or high pressure ball valve — hygienic applications, food processing, pharmaceutical lines, and corrosive or high-salinity industrial fluids.
3. Preventing Backflow with Non-Return Valves
Uncontrolled backflow damages pumps, pipes, and can contaminate clean water supply. Wherever fluid must travel upward or away from a pump source, a Non-Return Valve (NRV) acts as a one-way gate — it permits flow in one direction only, and closes automatically the moment upstream pressure drops or fluid tries to reverse.
Ball Valves — Full Bore, Heavy Duty & High Pressure Options
A ball valve is the go-to choice for a dependable ball valve shut off — a quarter-turn from fully open to fully closed, with a tight seal in either position. Our range spans domestic water lines through to demanding industrial installations.
1. Full Bore vs. Reduced Bore Ball Valves
A full bore ball valve (also called full port) has an internal bore the same diameter as the connected pipe, so fluid passes through with almost no restriction or pressure drop — the standard choice where flow rate matters, such as fire lines, main water supply, or industrial process lines. A reduced bore (standard port) valve has a smaller internal opening — cheaper and perfectly adequate for simple shut-off duty where flow rate isn't critical.
2. Heavy Duty & High Pressure Ball Valves
For demanding applications — industrial process lines, high-rise booster pump systems, boiler feed lines, or commercial fire protection — a standard-duty valve isn't enough. A heavy duty ball valve uses a thicker body wall, reinforced stem packing, and a more robust ball-and-seat design to handle repeated cycling without wear. A high pressure ball valve is rated and tested for a specific pressure class (commonly PN16, PN25, or higher for industrial systems) and should always be matched to — never exceed — your system's actual operating pressure.
3. Water Ball Valves for Home Plumbing
A water ball valve is the standard shut-off point for domestic plumbing — under sinks, at the main inlet, before water heaters, or at any branch line you may need to isolate for repairs. CPVC and brass water ball valves are the most common choices for Indian homes, selected based on whether the connecting pipe is CPVC/PVC or metal.
4. Industrial Ball Valve Applications
An industrial ball valve is built for continuous-duty environments — process plants, HVAC systems, water treatment facilities, and manufacturing lines — where reliability under frequent cycling and exposure to varied fluids matters more than cost. Stainless steel bodies suit corrosive or high-purity fluids; brass and cast iron cover most standard industrial water and utility lines.
5. Ball Valve Sizes (Including 2 Inch Ball Valves)
Ball valves come in a wide size range to match pipe diameter, from small 15mm (½") valves for domestic branch lines up to large industrial bores. A 2 inch ball valve (50mm) is a common mid-range size used for main distribution lines, booster pump inlets, and moderate-flow industrial connections — sitting between smaller domestic sizes and the larger bore valves used on primary supply lines.
6. Ball Valve Brands We Stock
THS Now sources ball valves from established ball valve manufacturers including Zoloto and Supreme, alongside The Hardware Store Now's own quality-checked range — so you're getting factory-tested, pressure-rated valves rather than unverified stock. Every unit is checked for consistent bore sizing, seal quality, and smooth quarter-turn operation before it reaches you.
Gate & Globe Valves
For main distribution lines and deep control systems, our heavy-duty gate and globe valves cover a different job than a ball valve. Gate valves offer minimal resistance when fully open, keeping fluid friction to an absolute minimum — the standard pick for main line isolation where you rarely open or close the valve but need it fully out of the flow path when open. Globe valves, by contrast, are built for gradual throttling — adjusting line pressure incrementally rather than snapping fully open or shut — making them the right choice for industrial boiler loops, cooling lines, and multi-tier building systems where fine control matters.
Non-Return Valves (NRV) — Check Valves for Backflow Prevention
Ensure total unidirectional flow security with our industrial check valves. Available in lift-type, swing-type, and dual-plate disc designs, these NRVs activate entirely on pressure differentials — no manual intervention or electrical power required. They're a critical addition for lines situated directly after water meters and booster pumps, where a sudden loss of upstream pressure could otherwise let fluid flow backward and damage equipment or contaminate the supply.
Foot Valves for Pumps
Protect your centrifugal pumps from losing their prime. Positioned at the absolute bottom of a suction pipe line inside a well or underground reservoir, our foot valves combine an integrated check valve with a rugged micro-mesh strainer — holding the water column securely inside the suction line while filtering out coarse mud, pebbles, and debris before they can enter and damage the pump impeller.

Frequently Asked Questions
1. What is the benefit of a Non-Return Valve?
A Non-Return Valve (NRV) automatically prevents fluid from flowing backward when a pump shuts down or line pressure drops. This shields booster pumps from backward hydraulic shocks, prevents clean water reservoirs from draining back into source wells, and eliminates the risk of contaminated wastewater siphoning back into your primary supply lines.
2. Which valve is best for an overhead water tank?
For the main inlet line filling an overhead water tank, a combination of a full bore brass water ball valve (for manual isolation during maintenance) and an automated float valve (ball-cock mechanism) works best. The float valve automatically shuts down water inflow once the tank reaches capacity, preventing overfilling and water wastage.
3. Are your brass valves corrosion-resistant?
Yes. The premium brass valves in the THS Now collection are forged from high-purity brass alloys that naturally resist oxidation and hard water scaling. For aggressive chemical environments, highly acidic fluids, or coastal outdoor installations, our marine-grade stainless steel (SS316) valve lines are the better choice.
4. What does "ball valve shut off" mean, and how is it different from throttling?
A ball valve shut off refers to using the valve purely to fully open or fully close a line — its intended function. Ball valves shouldn't be left partially open to regulate flow, since the high-velocity stream at a partial opening wears down the internal seat faster than a globe or needle valve designed for throttling.
5. What's the difference between a full bore ball valve and a standard ball valve?
A full bore ball valve has an internal opening matching the pipe's full diameter, allowing nearly unrestricted flow and minimal pressure drop — important for fire lines and high-flow applications. A standard (reduced bore) ball valve has a narrower internal passage, which is fine for simple shut-off duty but restricts flow slightly.
6. When do I need a heavy duty or high pressure ball valve instead of a standard one?
If the valve will be cycled frequently, used in an industrial or commercial system, or operate above typical domestic water pressure, a heavy duty or high pressure–rated ball valve is the safer choice — standard domestic-grade valves aren't built for that duty cycle or pressure class.
7. What size ball valve do I need — is a 2 inch ball valve standard for home use?
Most home plumbing uses 15mm–25mm (½"–1") ball valves for branch lines and fixtures. A 2 inch (50mm) ball valve is more common for main supply lines, booster pump connections, or moderate-flow industrial and commercial applications — check your existing pipe diameter before ordering.
8. Are THS Now's valves sourced from a reliable ball valve manufacturer?
Yes — our range includes valves from established brands like Zoloto and Supreme, alongside our own quality-checked stock, so every valve is factory-tested for pressure rating and seal integrity rather than unverified generic stock.
9. What's the best valve for an industrial water line vs. a home water line?
An industrial ball valve is typically built with a stainless steel or heavy brass body to handle continuous cycling and varied fluids, while a standard water ball valve (CPVC or brass) is sufficient for domestic supply lines with normal residential pressure and usage.
