Valve series VOFD

• The valves from the series VOFD are special 3/2-way valves for process automation for use in chemical and petrochemical plants. Here they are frequently used as pilot valves for butterfly valves and actuators. Their sturdy design and high resistance to Function, design • 3/2-way directly actuated poppet valves corrosion make these valves suitable for outdoor use under harsh ambient conditions. • The NAMUR flange pattern makes the solenoid valves especially suitable for quarter-turn actuators. The integrated spring chamber Safety • Can be used in emergency shutdown (ESD) applications • Suitable...

Solenoid valves VOFD

Flow rate up to 52 l/min General technical data Basic valve G1/4 Operating and environmental conditions Operating medium 1) Corrosion resistance class CRC 4 to Festo standard FN 940070 Particularly high corrosion stress. Outdoor exposure under extreme corrosive conditions. Parts exposed to aggressive media, e.g. in the chemical or food industries. Such applications may need to be safeguarded by special tests (d also FN 940082), using appropriate media.
