High Performance • Durable • Leak Proof
Self-acting pressure relief and sustaining valve for automatic pressure control without auxiliary energy.
Pressure control is critical in ensuring safe operating conditions and stability within industrial piping systems. Pressure Relief & Sustaining Valve Manufacturer in Africa provides valves that are suitable for preventing over-pressuring of systems and keeping the upstream pressure at a set level. Pressure relief valves are used to open when system pressure is above a set point; pressure sustaining valves are used to control downstream flow to maintain the required upstream pressure. Used in water distribution systems, oil and gas facilities, mining operations, chemical processing plants and other industrial utility systems where consistent pressure management is critical.
