Proportional throttle valve normally open

The tried and tested direct operated throttle valve in the nominal size M33 is now also available in a normally open execution. The valve is used in applications where maximum flow is required when the solenoid is in a deenergised state.

Via the solenoid current, the proportional valve can continuously adjust volume flows up to max. 55 l/min and be used in the pressure range up to 350 bar. The elaborate armature bearings, together with the coated and precisely coordinated valve parts, lead to a very finely dosed volume flow with low hysteresis. The valve is available as a 2-way function with the designation DOPPM33 and can be operated with all Wandfluh standard and special solenoid coils in the size of 45mm.
