  • Description:
  • Pneumatic PTFE PFA lined ball valve feature

    Pneumatic PTFE PFA lined ball valve is PTFE or PFA lined structure, which is used alikali,acid and other corrosive medium , which can fully instead of stainless steel bal valve, Pneumatic PTFE PFA lined ball valve is mounted with pneumatic actuator, achieving in the purpose of automatic control and remote control on the ball valve action.

    There are two types of pneumatic actuators mounted with the Pneumatic PTFE PFA lined ball valve, one type is single action pneumatic actuator (which is also called spring return pneumatic actuator); the other type is double action pneumatic actuator. Normally, the clients select the spring return pneumatic actuator, because this type of pneumatic actuator needs only one air supply.
