Compact explosion-proof solenoid valve for pnematic control

Compact explosion-proof solenoid valve
Compact type explosion-proof solenoid valve effectively layouting a terminal box to ensure easy wiring.
Connection interface of the main body is available in two types. The actuator can be mounted or mounted in a most suited manner.
(1) NAMUR standard model
  This is a five-port solenoid valve for rotary actuator operation adopting the mounting interface specified in NAMUR standard.
(2) Direct piping type
  This is a five-port solenoid valve for connecting to the actuator by piping connection. Single installation at a remote position, or coupling type by manifold structure may be realized.

454 Series 5-Port Solenoid Valves Explosion-proof

  • 454 Series 5-Port Solenoid Valves
By effective layout of terminal box, ease of piping works is assured in this compact type explosion-proof direct piping type solenoid valve.
