Pressure relief / hold pressure valve is mainly used in fire protection or other water supply systems to prevent system overpressure or maintain the pressure of fire protection water supply systems. Pressure Reducing Valve can also reduce the impact of water hammer after the fire pump is turned off. Hydraulic Control Valve is also used for water hammer installations in large water supply systems. In addition, a clean filter is installed at the inlet of the valve control system. The fluid characteristics are used to prevent suspended particles with a large specific gravity and a large diameter from entering the control system. The Flow Control Valve system has stable movement, high strength and long service life.
