ZZVP micro pressure self- operated regulator description
ZZVP ultra-low micro-pressure self-operated regulator for nitrogen supply does not need external energy. The medium being modulated is served as the power source, the pilot of the pressure valve is introduced to control the position of the its spool. And the flow rate of the medium flowing through the valve is changed to keep the valve back pressure (type B) or front pressure (type K) constant.
