Pressure & System Protection

Pressure and system protection valves safeguard pipelines, process equipment and industrial installations from pressure surges, hydraulic shock, vacuum conditions and excessive system pressure. Designed to improve system reliability and extend equipment life, these valves protect pumps, pipelines, tanks and process machinery from damaging pressure fluctuations.

Our range includes pressure relief valves, pressure limiting valves, water hammer arrestors, anti-surge valves, vacuum relief valves and air release valves suitable for water distribution, pumping systems, industrial process plants, HVAC systems and general fluid handling applications.

Manufactured from brass, bronze, ductile iron and stainless steel, our protection valves are available with threaded and flanged connections for low and high pressure systems across a wide range of industrial and municipal applications.

Product Range

✓ Pressure Relief & Limiting Valves

Protect pipelines and equipment from excessive pressure by automatically relieving or limiting system pressure.

✓ Water Hammer Arrestors

Reduce hydraulic shock and pressure surges caused by rapid valve closure or pump shutdown.

✓ Air & Vacuum Relief Valves

Prevent vacuum formation, admit air during draining and release trapped air during filling to protect pipelines and pumping systems.
