Product Description
- Electric switch-on valve for safe compressed air supply and venting of pneumatic systems at 230 V operating voltage – ideal for automated applications with high safety requirements.
- The HEE‑D 230 V switch-on valves are robust 3/2-way modules with piston slide technology and spring return, which are closed in the idle state and fill the entire system when activated – when switched off, safe venting takes place.
- With a closed design, ceramic coil and long service life (100% duty cycle), they offer reliable protection against moisture and condensation.
- The metal construction (die-cast aluminium housing, NBR seals), KBK 2 corrosion protection classification, LABS and RoHS compatibility, and flexible installation (any position) make them high-quality components for process automation.
- Available in mini, midi and maxi versions with connection threads from G 1/8" to G 1" – perfect for integration into modular maintenance units.
