Product Detail
The ZZV (C) type self operated micro (differential) pressure regulating valve does not require external energy. It uses the energy of the controlled medium as the power source and introduces an actuator to control the position of the valve core to change the interception area, thereby changing the pressure difference and flow rate at both ends, achieving the goal of controlling the pressure stability (post valve type) or pressure relief (pre valve type) behind the valve. It has the advantages of sensitive action, good sealing performance, and small pressure fluctuations, and is widely used for micro pressure control of gases in various industrial equipment.
