Pressure Regulation

Pressure regulation valves control and maintain system pressure in pipelines and industrial applications. Includes pressure reducing, relief and sustaining valves.

Show Sub Categories

Pressure reducing valves (PRV) regulate and maintain stable downstream pressure in water and industrial systems. Adjustable valves available in brass, stainless steel and flanged designs with pressure gauge options.

Pressure Reducing Valves

Pressure sustaining valves maintain constant back pressure regardless of downstream flow or demand. Suitable for water and industrial systems with threaded and flanged options from 1/2" to DN1000.

Valve / Product Type

Manual + Mechanical Control0

Air valves that are controlled manually and mechanically

Pressure Reducing0

Pressure reducing valves (PRV) reduce and maintain stable outlet pressure

Pressure Sustaining0

Pressure sustaining / back pressure valve, maintains a minimum preset upstream (Inlet) pressure, valve will close if pressure drops to set pressure and reopens when inlet pressure increases again.

Proportional Modulating0

Flow regulating valves with manual or electric modulating 4-20mA control.

Solenoid Valve0

Valves controlled by electrical signal via a solenoid or electro magnet.

Function

2/2 Failsafe Closed0

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays closed (Failsafe) requires power to open

Proportional / Modulating0

Valve opens proportionally according to signal input, either 4-20mA, 0-10v or 0-5 volt. Example 4mA valve closed, 8mA 25% open, 12mA 50% open, 18mA 75% open and 20mA fully open.

Operation

Direct Acting0

Directly controls flow without external pressure assistance operates from vacuum upwards.

Pressure Assisted0

Operate via pilot pressure control and require a minimum pressure difference between inlet and outlet from 0.5 Bar.

Options required

Anti Water Hammer0

Prevents or reduces water hammer caused by sudden changes in fast moving fluid flow.

Manual Control0

Valves that require manual input to operate such as lever, button or switch

Mounting Holes0

Supplied with additional threaded holes typically in the base, typically for securing to a baseplate.

Outlet - right angle0

The outlet port is at right angles to inlet port, ideal for space efficiency.
