The factory to provide Hydrogen cylinder pressure reducer

Hydrogen pressure reducing valve is an essential part of pneumatic control valve, the main function is to reduce the pressure of the gas source and stable to a constant value, in order to facilitate the control valve can be used to obtain a stable source of power for regulating control.
In the form of the structure can be divided into the valve after the pressure piston type, lever type and corrugated tube; can be divided into single seat and two seat according to the seat number; according to the different position of the valve flap can be divided into the positive effects type and the reaction type
Hydrogen pressure reducing valve operation by the valve after the pressure control. When the pressure sensor detects the pressure of the valve, the valve opening decreases; when the valve is detected, the pressure decreases, the valve opening increases, in order to meet the control requirements.
Hydrogen pressure relief valve, the valve must be in a certain extent than the system value; even if the maximum or minimum flow, it should also be able to respond to the positive role or the reaction control signal. These valves should be selected for useful control, i.e., the maximum flow rate of 20% to 80%. Normal geometric model or have geometric properties. These types of valves have the best flow characteristics and the flow range as required by proportional control.
There are many kinds of valve, common are: pilot piston type pressure reducing valve, diaphragm valve, corrugated tube type pressure reducing valve, proportional valve, self operated pressure reducing valve, direct acting piston valve, back pressure regulating valve and so on. They are suitable for different working media.
Different forms have different concrete working principles. But the general principle is: pressure relief valve is through the opening and closing parts of the throttle, the import pressure is reduced to a need for export pressure, and to maintain the stability of the outlet pressure. But the general valve are required to import and export pressure must be greater than or equal to 0.2Mpa.
