Self-operated Pressure Control Valve With Pilot

Self-operated Pressure Control Valve With Pilot

    The SV self-operated pressure control valve with pilot utilizes the fluid own energy to adjust the valve opening automatically without any external power source. The SV automatically pressure control valve is widely used as inlet valve or outlet valve for pressure reduction and stabilization of air, liquid and vapor in industries of petroleum, chemical engineering, electric power, metallurgy, food, light textile, machinery manufacturing and residential buildings etc.
