- The pressure relief/sustaining valve consists of a main valve, pressure relief/sustaining pilot valve, needle valve, ball valve, micro filter, and pressure gauge, forming a hydraulic control piping system. Utilizing hydraulic automatic operation, it can function both as a pressure relief valve and a pressure sustaining valve. When used as a pressure relief valve, it maintains the water supply pressure below a set safe value; when used as a pressure sustaining valve, it maintains the water pressure upstream of the main valve above a set value, ensuring the upstream water supply pressure.
This product utilizes hydraulic power control, requires no additional devices or energy sources, is easy to maintain, and serves multiple functions with a single valve.
Applications
This series of valve products is widely used in water supply network systems for high-rise buildings, residential areas, and urban water supply projects.
