Valve series VOFD
2022-11-11
Key features
▲General
●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 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 rebreather function protects quarter-turn actuators with spring return (single-acting cylinders and actuators) against contaminated ambient air and weather influences such as rain.
●With German Technical Control Board (TÜV) approval up to SIL 3.
▲Function, design
●3/2-way directly actuated poppet Valves
▲Safety
●Can be used in emergency shutdown (ESD) applications
●Suitable for use in safety-related systems up to and including SIL 3 to IEC 61508
▲Robust
●The surface of the valve housing is Ematal coated. This treatment involves converting the aluminium surface into a very hard aluminium oxide layer with titanium oxide intercalations, which makes the valves extremely resistant to wear and abrasion and gives them first-class sliding qualities. This provides optimum protection against atmospheric and chemical influences.
▲Economical
●One valve, two connection options
●Port patterns to NAMUR for direct installation on the actuator as well as G and NPT threaded connections
●Manual override can be ordered optionally
●Manual override can be retrofitted and removed again – no additional valve version required
