Electric switch four-way valve _ pneumatic four-way valve industry pneumatic valve _ pneumatic components factory

Pneumatic valve pneumatic valve spool valve pneumatic components factory is one of the new research production pneumatic valve, has advantages of good sealing performance, long life and other characteristics; Switch four-way valve just by pneumatic valve actuator or electric valve actuators will choose 90 °, the aerodynamic body at the same time to switch of two kinds of medium flow, achieve the effect of one valve is multi-purpose. Pneumatic four-way valve working principle: electric switch four-way valve, also known as 'four-way solenoid', each flange port within it are equipped with seal steel ring, sealing ring steel within the port is pneumatic line, and is equipped with four fluorine in them port sealing ring, ptfe sealing ring and valve pneumatic seal, seal steel ring outside the port and vice valve body between each flange with compensation spring, after the assembly, the compensation under the action of the spring, ptfe sealing ring and valve pneumatic di a seal, four fluorine material wear-resisting, suitable for frequent on-off of the seal, with ptfe sealing ring is worn, the compensation spring constant inward presumption of seal steel ring, ptfe sealing ring and valve pneumatic remain sealed state, when the ptfe sealing ring is worn out or fire, ptfe sealing ring is completely destroyed when the compensation spring push the top seal steel ring, flush with the valve pneumatic metal sealing formation, this structure design has the function of automatic compensation and fire prevention. Four-way valve pneumatic pneumatic valve is equipped with the valve stem, the top of the stem through the valve cover, and the lower part of the valve stem has a bar, a reinforcement stuck inside the cover of the port, once the seal leakage occurs, has a certain pressure medium rushed into the body cavity, the valve stem is also under pressure, the design of steel structure can prevent the valve stem in the inner cavity medium pressure out of the damage caused by accident. Electric switch four-way valve is a kind of special used for drying device (pressure swing adsorption (psa) No hot dryer, micro dryer, hot dryer, waste heat dryer, etc. ) , the realization of the twin towers automatic switching of the new valve, pneumatic valve spool is avoided by the original four film cut-off valve or pneumatic butterfly valve group composed of complex structure, pipe line, large volume, installation is more convenient, diaphragm is damaged, the cost is higher shortcomings. Characteristics of pneumatic four-way valve, pneumatic four-way valve has a small volume, convenient installation, reliable and durable, good sealing, sensitive switch etc. , the service life of 600000 times more. Pneumatic components factory specializing in the production of pneumatic valve spool valve industry manufacturers, customers can according to the electric switch four-way valve or pneumatic four-way valve body materials, working temperature, nominal pressure, nominal size and flange standard and other technical parameters selection and reference. : electric four eccentric butterfly valve _ four eccentric butterfly valve FQ941F/H intelligent electric explosion-proof pneumatic valve tee working principle of the pneumatic valve
