Quick Relief Hydraulic Control Valve
Areas of Use
Fast-Acting Safety Valve for Pressure Protection in Plastic Systems
The Plastic Quick Relief Control Valve is a high-performance safety valve engineered to protect water systems from sudden and excessive pressure surges. Designed with a corrosion-resistant plastic body, it provides a lightweight yet durable solution ideal for modern plastic piping networks.
Equipped with a precision pilot mechanism, the valve continuously monitors the inlet pressure and reacts instantly when the system pressure exceeds the preset limit. It opens rapidly to discharge excess pressure safely to the atmosphere, preventing potential system damage. Despite its fast-opening function, the hydraulically operated design ensures a slow, controlled closing movement — preventing secondary pressure spikes and maintaining overall system stability.
With a 100% leak-tight sealing feature, this valve delivers long-lasting, maintenance-free performance. It can be installed individually at critical points in the system or used in conjunction with pressure reducing control valves as an additional safety and relief component. Combining high chemical resistance, dependable operation, and precision control, the Plastic Quick Relief Control Valve is an ideal choice for protecting plastic water distribution and filtration systems.
