Pressure Control

Pressure control solutions for regulating, monitoring and protecting system pressure in industrial and pipeline applications. Includes regulation, measurement and protection systems.

Show Sub Categories

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

Pressure Regulation

Pressure measurement devices for monitoring system pressure in industrial and fluid applications. Includes pressure gauges for visual indication, pressure transmitters for signal output (4–20mA / 0–10V), and pressure switches for automated control integration. Suitable for compressed air, water, gas and process systems.

Pressure Measurement

System protection valves designed to safeguard pipelines and equipment from pressure surges, vacuum conditions and hydraulic shock.

Includes water hammer arrestors to absorb shock waves, vacuum breaker and air vent valves to prevent negative pressure and system collapse, and protection devices for industrial fluid and compressed air systems.

Used in water distribution, pumping systems, HVAC and process installations to improve reliability and extend equipment life.

System Protection

Foot valves for pump suction systems with integrated strainer and non-return function. Maintain prime, prevent backflow and protect pumps. BSP and flanged sizes available.

Suction & Prime Aid (Foot Valves)

Electronic pressure control devices for precise and automated regulation of system pressure in industrial and process applications. Includes proportional pressure regulators, electronic pressure regulators and closed-loop control solutions using 0–10V or 4–20mA signals. Suitable for air, gas and liquid systems.

Valve / Product Type

Coaxial Valve0

Condensate drain0

Automated + time control drain valves

Filters Regulators & Oilers 0

Air pressure regulator with air filter with air lubrication system. Provides stable outlet pressure whilst removing debris and 90% moisture the finally providing oil mist to lubricate downstream equipment.

Manual + Mechanical Control0

Air valves that are controlled manually and mechanically

Pressure Switch / Transmitter0

Pressure switches and pressure transmitters

Pressure Reducing0

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

Pressure Relief0

Safety pressure relief / pressure limiting valve (PLV), stays closed until pressure reaches set pressure - then quickly opens, releasing any excess 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.

Vacuum Breaker + Generators0

valves that release trapped air + vacuum or generate vacuum

Function

2/2 Failsafe Closed0

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