Sturdy Valves for Liquid, Gas & Other Transport Systems

Explore valves at F.W. Webb to find the right control modules for any system. From butterfly and gate valves that open and close to let liquids pass through to grooved valves often used in fire suppression systems, we carry reliable options suited to work in a range of applications.

Needle, Diaphragm, and Other Internal Mechanism Valves

Needle valves operate using a small plunger to speed up or slow down the flow of material; they are most often used to protect delicate gauges from surges in pressure. Plug valves are cylindrical and use a quarter-turn manual motion to restrict flow. Both diaphragm and solenoid valves control the flow of liquids or chemicals via a liner or electric switch in the body. Find actuated and control valves for gas and liquid system containment. Actuated valves use a mechanical device known as an actuator for regulation while control valves use a handle or electric setup to maintain pressure levels.

Backflow, Check, Backwater & Isolation Valves

Backflow prevention, backwater, and check valves all keep water from running in a reverse direction during transport; some automatically shut off a supply line if a nearby sewage or drain line backs up, keeping potable water safe from contamination. Use plastic check valves to differentiate drinking and non-potable water in separate pipes and isolation valves to move liquids or gasses into specific areas in a system.

Safety Valves for High-Pressure Gas Transport

Flow control valves regulate the rate of compressed air or gas release. Similarly, gas valves, including ball and meter, work with various transport systems to regulate the movement of pressurized gasses. Relief valves also help control excess pressure and provide safety in flammable gas systems. Globe valves use an internal disc to regulate or completely shut off the flow and can be used in place of pressure relief or check valves. Choose a laboratory valve when precise exacting is needed.

Sillcocks, Hose Bibs & Plumbing Valves

Sillcocks and hose bibs are used as faucets on the exterior of a structure to provide water for outdoor use. Use a water meter valve to control the flow of water to a metering system; this eliminates the need to shut off the water while the meter is being serviced.

Brass and plastic ball valves work in a wide variety of systems, including residential and commercial plumbing, HVAC maintenance, and chemical transport; use a CPVC ball valve in hot water applications up to temperatures up to 180°F. Mixing valves allow cold and hot to commingle, and deliver tempered water to a shower or tub; choose a washing machine valve for cold and hot water dispensation to standard household fixtures. Pressure-reducing valves are used to join city water mains to residential plumbing systems and reduce the high intensity of municipal systems.

Essential Valves for HVAC Units

Boiler drain valves are used to remove water and sediment from a holding tank inside a heating system, while boiler fill valves do the opposite and replenish a supply. Radiator valves help control the amount of heat a unit gives off by keeping water temperature consistent.

The correct valves provide control over a liquid or gas transport system and also increase efficiency and cost-effectiveness. Browse essential valves at F.W. Webb to find the attachments you need to complete any setup.
