spoolpoppetrotary

Indirectly controlled pilot valve for particularly demanding usage conditions. Redundant version for safety-related systems up to SIL3. • Suitable for process automation in the chemical and petrochemical industries • Suitable for outdoor use under harsh, dusty ambient conditions • Especially suitable for quarter turn actuators thanks to NAMUR flange pattern • Pneumatic valve can switch between internal and external pilot air • Variants with safety functions • Variants in accordance with EU Explosion Protection Directive (ATEX) • The valves of series VOFC are special3/2-way and 5/2-way valves for process automation and applications inchemical and petrochemical installations, where they are frequentlyused as pilot valves for butterflyvalves and actuators. Their sturdydesign and high resistance to corrosion make these valves suitable foroutdoor use under harsh ambientconditions. • With the flange pattern to NAMUR,the solenoid valves are particularlysuitable for quarter turn actuators.The integrated spring chamberre-breather function protects quarter-turn actuators with spring return(single-acting cylinders and actuators) against contaminated ambientair and weather conditions such asrain. • With German Technical ControlBoard (TÜV) report up to SIL3 Function, design • 3/2-way or 5/2-way, single or double solenoid, depending on the type • Pilot-actuated piston spool and poppet valves
