SG iron pressure relief valve SK500X-10/16/25Q

Product Overview

The 500 × pressure relief special pressure valve is mainly used in fire or other water supply systems to prevent system overpressure or maintain the pressure of the fire water supply system. After the fire pump is turned off, the impact of water hammer can be reduced. Also used for water hammer fire protection devices in large-scale water supply systems. And a self-cleaning filter screen is installed at the inlet of the valve control system, which utilizes fluid characteristics to prevent suspended particles with high density and diameter from entering the control system, ensuring smooth circulation and reliable operation of the cold door. The system operates smoothly, has high intensity, and has a long service life.

Structural characteristics and applications

The 500 × pressure relief valve consists of a main valve, a pressure relief/special pressure pilot valve needle valve, a ball valve, a micro filter, and a pressure gauge to form a hydraulic control connection system. By utilizing hydraulic automatic operation, it can be used as both a pressure relief valve and a pressure holding valve. When used as a pressure relief valve, it can maintain the water supply pressure below the set value; Used as a pressure holding valve, it can maintain the upstream water pressure of the main valve above the set value and maintain the upstream water supply pressure of the main valve. The 500 × pressure relief valve uses hydraulic self control, does not require other devices or energy, is easy to maintain, and can be used for multiple purposes with one valve. The 500X pool pressure valve product is widely used in water supply pipeline systems such as high-rise buildings and living areas, as well as urban water supply projects.
