Asco Series 342 Shut-Off Valve

Below you will find brief product information for Asco Series 342 Shut-Off Valve:

  • The Asco Series 342 Shut-Off Valve is a 2-way, 3-port valve designed for use in a variety of applications, including:
    • Shutting off the flow of air or gas in a трубопровод
    • Controlling the flow of air or gas to a pneumatic cylinder
    • Venting the air or gas from a pneumatic system
  • The valve is constructed of brass and has a Buna-N seal. It is rated for a maximum pressure of 150 psi and a maximum temperature of 180°F.
  • The valve is operated by a solenoid, which is controlled by an electrical signal. The solenoid is spring-loaded to the closed position, so the valve will close if the electrical signal is lost.
