            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.

            Matters needing attention in pneumatic low temperature regulating valve


            1. Should be installed vertically on the horizontal pipeline, in special cases need to be installed horizontally or inclined, generally should be supported. The garden plate installed on the wall of the incubator should be parallel to the heat preservation box wall.


            2. Should be installed near the ground or floor, in order to maintain maintenance, positioner or handwheel mechanism, should ensure that the observation, adjustment and operation of convenience.


            3. Generally, by-pass pipes are installed to switch to manual operation when the automatic control system fails or is repaired, so as not to stop production.


            4. When the handwheel mechanism is installed, manual operation of bypass pipeline can be omitted, and the opening can be limited. When it stops using, the handwheel mechanism must return to the original neutral position to facilitate the normal operation of the automatic control system.


            5, when installing, the flow direction of the medium should be consistent with the direction of the valve body.


            6, before installation, pipe cleaning and welding slag should be cleaned. After installation, make full opening, piping and so on to clean and test the sealing ability of the joints.
