Daily use pneumatic valve

, scope: this specification applies Yu Falan connect the electric ( Or pneumatic) Valve. And: by electric ( Or pneumatic) Actuator and the valve body parts, its connection by stent and the connecting shaft. , pneumatic valve use restrictions) Temperature and pressure limits) Nameplate shows a valve in the maximum and minimum operating temperature is allowed to the maximum operating pressure. ) Using PTFE or RTFE seat and seal material, operating temperature should be between degrees and degrees. Other types of operating temperature of the seat and seal, should be check. ) Cryogenic valve nominal pressure level, PN) , can show that the maximum working pressure in normal temperature condition. （ For example: the PN. , shows that its operating temperature in - C - C when the maximum working pressure for the Bar, 。 MPa) ） 。 ) Electric or pneumatic actuators notes refer to its corresponding specifications.
