                ZMAP Pneumatic Film Low Temperature Single Seat Regulating Valve/ZMAN Pneumatic Film Low Temperature Double Seat Regulating Valve is a deformation product of single seat and double seat regulating valve. It differs from normal temperature in that it uses long neck upper cover to make packing work at normal temperature. Pneumatic thin film cryogenic control valve is suitable for medium (such as liquid oxygen, liquid nitrogen, etc.) in low temperature and strong state of - 60 ~ - 250 C. In order to ensure the accuracy of adjustment, positioners must be used.


                Structure principle of pneumatic low temperature regulating valve


                The pneumatic low temperature control valve is composed of pneumatic membrane actuator and single-seat and double-seat control valves which can withstand low temperature.


                The signal pressure from the regulator is fed into the air chamber of the pneumatic membrane actuator to generate thrust. The valve core is driven by connecting rods. The change of the valve core position makes the valve flow cross-sectional area change and realizes the adjustment of the medium flow rate.
