BXS 3/2 Pilot-Operated Direct-Acting Solenoid Valve

Brand: Bifold - by Rotork
Request Information
Features
  • SIL 3 capability: The product has met manufacturer design process requirements of safety Integrity Level (SIL) 3.
  • Force balanced valve design with high safety factors to de-energize at all pressures in normally open and normally closed configurations.
  • 100% computerized diagnostic testing to ensure each solenoid valve is proven along with confirmed safety factors.
  • Bifold has state of the art product qualification and production equipment including flow (Cv), environment (-70° to 180° C), function and leakage testing and data logging.
  • The standard solenoid operator is a holding magnet type which ensures the valve will operate in damp conditions. The risk of corrosion to internal components is reduced, unlike other valve types that incorporate a solenoid core tube design with a 'wetted' armature that will only operate in dry air conditions!
  • Tolerant to moist air in control lines.
  • The standard solenoid valve has proven arctic service and low temperature performance.
  • Products are manufactured, inspected, assembled and tested in our state of the art production facilities.
  • Large clearances, metal back up to seals and no knife edge sealing to prevent long term valve sticking.
  • Dry solenoid armature to prevent corrosion and affecting safe shut down.
  • Simple maintenance - Removable transient suppression diode on Ex d DC solenoid valve assemblies and removable solenoid coil without removing valve from the tubing.
