253 2/2-Way Solenoid Valve
Brand: Burkert Fluid Control SystemsType 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
