253 2/2-Way Solenoid Valve

Brand: Burkert Fluid Control Systems
Request Information
Favorite

Type 253 is a 2/2 normally-closed plunger-type solenoid valve. When energized, the solenoid armature is pulled-in against a spring and the valve opens.

As a standard feature, the valve seat is made of stainless steel in order to avoid erosion. The solenoid epoxy encapsulation efficiently dissipates the heat generated by the coil.
Features
  • Normally closed
  • Body material: Brass
  • Compact design
  • Fluid temperatures 0° to 180° C (0° to 356° F)
  • Coil replacement does not require fluid to be isolated
