21HT-HN-HF series

Product catalog summary
Overview: The document provides technical specifications and operational guidelines for solenoid valves, specifically models 21HT3K0Y110 to 21HT6K0Y250-S, and related components. These valves are designed for fluid interception without requiring a minimum operational pressure.
Specifications:
  • Materials: The valve body is made of brass (UNI EN 12165 CW617N), with stainless steel used for the armature tube, fixed core, and plunger. The phase displacement ring is copper, and the spring is stainless steel.
  • Seals: Standard seals are NBR + PA for temperatures between -10°C and +90°C, with optional FKM + PA seals for temperatures up to 140°C.
  • Pressure: Maximum allowable pressure is 16 bar.
  • Protection: Valves have a protection degree of IP 65 according to EN 60529 (DIN 40050) when fitted with a connector.
Usage: Suitable for automation, vacuum packaging, and heating applications, compatible with air, gasoline, fuel oils, inert gas, water, and mineral oils.
Coils: Made from 100% virgin material, with power absorption options of 8W, 12W, and 14W, designed to operate at temperatures up to 180°C (class H).
Maintenance and Spare Parts:
  • Maintenance kits include components such as complete armature tubes, gaskets, and diaphragms with plungers.
  • Spare parts are available for various components, including coils and gaskets.
Notes: ODE reserves the right to make technical and aesthetic modifications without prior notification. Guidelines are provided for replacing seals and using connectors conforming to ISO 4400 and IEC 335 standards.
Additional Specifications:
  • Models 21HF6K0V250 to 21HF8K0V400 are also covered, designed for fluid interception with no minimum operational pressure, ensuring reliability and durability.
  • Materials include brass for the body and stainless steel for the armature tube and plunger, with copper phase displacement rings and stainless steel springs.
  • Coils are available in power ratings of 8W, 12W, and 14W, with a maximum allowable pressure of 16 bar.
  • Valves comply with the Pressure Equipment Directive 97/23/CE and have CE approval for models 21HF7 to 21HF8, with electrical conformity according to IEC 335.
  • Gaskets are available in NBR, EPDM, and FKM, suitable for various media.
  • Maintenance kits and spare parts are available, with specific codes for ordering components.
  • Detailed dimensions for each valve type are provided, including pipe size, power absorption, and coil dimensions.
