Overview

Shanghai Tingyang self-control valve ZZYM type self operated sleeve regulating valve does not require external energy. It uses the energy of the regulated medium as the power source, introduces an actuator to control the position of the valve core, changes the pressure difference and flow rate at both ends, and stabilizes the pressure before or after the valve. It has the advantages of sensitive action, good sealing, and small pressure set point fluctuations, and is widely used in automatic control of pressure reduction and stabilization or release and stabilization of gas, liquid, and steam media.
