The ZPL620F (ZZVP) self-operated micro-pressure regulator requires no external energy supply. It utilizes the energy of the controlled medium itself as the power source, introducing it into the actuator to control the position of the valve plug, thereby changing the throttling area, adjusting the pressure difference and flow rate at both ends, and achieving the purpose of stabilizing the outlet pressure (downstream type) or relieving inlet pressure (upstream type).
Featuring advantages such as sensitive action, excellent sealing performance, and minimal pressure fluctuation, it is widely applied in micro-pressure control of gases in various industrial equipment.
