2/2-Way Solenoid Valve Type 253 Advantages/Benefits Normally closed Body material: Brass Compact design Fluid temperatures up to 180 °C Coil replacement does not require fluid to be isolated
Applications
- Neutral gases and liquids, pneumatic control
- High temperatures, such as hot water, steam, hot air, thermal oils
- Heating
- Sterilizing
- Impregnating Design/Function 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. Direct-acting, G 1/4 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 gene- rated by the coil. Fluid Control Systems
