China Manufacturer Floating Ball Valve Differential Pressure Valve for Sealing Oil System


Differential Pressure Valve

977HP Differential Pressure Valve is used on the sealing oil system of generator. It compares the sum of the hydrogen pressure and the spring pressure with the oil pressure, when there is a pressure difference, the stem will move up and down, affecting the valve opening, causing the outlet flow and pressure to change accordingly, and finally achieving pressure balance.
