Product Description
- Pneumatically operated shut-off valve (HEL-D) for safe venting and de-pressurising of pneumatic systems during start-up and shutdown processes – ideal for automated systems with high safety requirements.
- HEL-D switch-on valves are pneumatically controlled 3/2-way valves that are closed in the idle state and build up system pressure when activated, while venting when switched off.
- Spring-centred reset and a metal, corrosion-resistant design ensure high reliability and durability.
- They are available in mini, midi and maxi sizes with different connection threads (G 1/8" to G 1"), enabling flexible integration into various pneumatic systems.
- Typical applications include production lines, automation and safety systems where controlled pressure build-up is essential.
