• Swing check valve - uses a swinging disc that is pushed open by fluid flow in one direction. When the flow stops or reverses the weight of the disc swings it back into a closed position.

Series PRS patented Stabilizer is used with Series PRA. The Stabilizer reacts to downstream liquid pressure and provides continuous feedback control to the compressed air supply, for even greater regulator sensitivity and performance. This is a Specialty Custom product; consult factory for availability. Minimum quantities may apply.

PR - PRESSURE REDUCING - FIXED SET-POINT - Series 100. The valve maintains a preset downstream pressure, regardless of upstream pressure or flow rate ...

Both valves are suitable for wastewater, and the choice will depend on the final system design and usage. The ball check valve is self-cleaning by design, although generally rated to lower working pressures.

Waterpressure regulator

Protect water systems in the home from excessive incoming water pressure and optimize homeowner comfort.

Pressure Reducing Regulators are the most common type of regulator that reduce an unregulated inlet pressure to a desired outlet pressure.

Thankfully for a UK water provider, the T-T Flow team were on hand to fabricate the perfect check valve replacement for their clean water pumping station.

• Double hinge flap valve - simple valves featuring a flap attached with two hinges that allows flow in one direction and closes when flow stops or reverses.

Butterfly valve

Series PRHU Downstream pressure reducing valve features metal ion-free EPDM large area rolling diaphragm, ultra-smooth operation and isolated spring control. BCF spigots in 1/2″ – 3″ or 20 – 90mm sizes; Kynar 740 body and Class 100 clean/double bag procedure standard. Provides highest flow with minimal pressure droop among high purity regulators; set pressure range 10-125 PSI.

• Spring check valve - uses a spring-loaded disc that sits on a seat in the valve body and is held in place by a spring. Pressure from fluid flow in one direction pushes the disc away from the seat and allows fluid to pass. When the flow stops, the spring forces the disc back onto the seat.

In order to prevent this from happening again a £5million flood defense scheme was initiated to protect over 50 homes situated on the river bank, with essential non-return valves supplied by T-T Flow.

Series PRA/PRAM features two opposing large area frictionless rolling diaphragms. Process pressure is applied to one of the diaphragms; air pressure is applied to the other. Because the air pressure can be maintained with more accuracy than the force provided by a spring, the PRA/PRAM offers greater sensitivity and less variance from set pressure than any thermoplastic pressure regulator previously available. The PRA/PRAM can be used in combination with Plast-O-Matic’s patented Stabilizer which measures downstream liquid pressure and provides continuous feedback control for even greater sensitivity and performance. Molded and machined valves in 1/4″ through 3″ and metric pipe sizes in popular thermoplastic materials with a wide range of connection types. Set range 5-125 PSI. This is a Specialty Custom product; consult factory for availability. Minimum quantities may apply.

Series PR/PRH/PRHM Downstream pressure reducing valve features large area rolling diaphragm, ultra-smooth operation and isolated spring control. Molded and machined valves in 1/4” through 3” (for 4” consult factory) and metric pipe sizes in popular thermoplastic materials with a wide range of connection types. Proven design provides highest flow with minimal pressure droop. While some valves may be limited by size or material, most models provide set range of 10-125 PSI.

Series UPRS Downstream pressure reducing valve features full shutoff design (pressure will not equalize in a no-flow condition) and the ultimate purity levels, as verified by independent test labs. BCF spigots standard; flare, sanitary, and other connection types available. 20 – 63mm sizes; Kynar 740 body. High purity CDB-16 (8 hour hot / 8 hour cold DI rinse) procedure is standard; clean and double bag in class 100 (ISO 5) clean room. Ultimate purity with excellent flow performance; set pressure range 10-100 PSI. Available with or without isolated pressure gauge.

PressureReducing Valve

Check valves, also known as non-return valves, only allow liquid to pass through in one direction. Preventing backflow, or reverse flow, of liquids is essential to protecting pumps and other components from damage, protecting buildings from flooding and preventing clean water contamination.

Regulating valve

For a client in urgent need of a reliable reverse flow prevention solution, our experts were able to pick from a large on-site stock of products to provide a fast turnaround on a set of duckbill check valves.

All check valves are designed to prevent pipeline backflow and prevent water contamination, equipment damage and flooding; there are different models that are designed for optimal performance in varying applications:

Address common well and municipal water problems — like iron, sediment, sulfur, chlorine and more — with targeted whole house water filtration that delivers ...

With over 35 years of innovative valve design experience, our check valves (also known as non-return valves) feature lightweight and robust construction for long and reliable operations. Our range of automatic check valves is suitable for use in potable, clean and wastewater applications; with swing, wafer, axial, ball, non-slam recoil and backflow preventer designs available.

PRV valve

• Twin plate check valve - two half-circle shaped plates are hinged and located inside the valve body, the plates swing open to allow flow in one direction, swinging shut if flow reverses.

• Recoil check valve - Similar to a swing check valve, however the recoil valve has an inclined seat and body profile to reduce the damaging effects of water slam.

• Ball break valve -  a self-acting valve that uses a ball to prevent backflow.  As the flow subsides the ball falls back into the valve seat, creating a seal and stopping any media from passing in the wrong direction.

Accurately reduce and regulate steady or varying inlet pressures and maintain a constant, predetermined maximum outlet set pressure. Offered in spring controlled, air controlled, differential controlled and ultra-pure designs, Plast-O-Matic regulators are consistently recognized as the industry’s top performers for maximum flow with minimal drop-off from set pressure. ½” through 3”; for 4” consult factory.

Swing check valves are generally installed horizontally, but they can be installed vertically depending on the required set-up. Contact our experts for more information.

Series PRD/PRDM is a differential pressure regulator with a port for a downstream pressure sensing line. The sensing line feeds the pressure downstream of the equipment being protected to the top of the spring housing, which assists the spring in keeping the regulator open against the pressure directly at the regulator outlet. When pressure downstream begins to drop (as it would when a filter becomes more and more clogged), the regulator begins to close and becomes fully closed when the differential setting is reached. This assures against overpressure across the equipment. Molded and machined valves in 1/4″ through 3″ and metric pipe sizes in popular thermoplastic materials with a wide range of connection types. Differential set range 5-50 PSI.
