8E Interlock Lever for Switchgear Product Background: Richge is a manufacturer of 8E Interlock Levers for switchgear in China, specializing in high-precision components that ensure reliable operation and safety in electrical systems. Our interlock levers are designed to provide secure and efficient control mechanisms within switchgear assemblies.

SOLH 50 series flameproof pilot solenoid valves cover two models: 50-VFE 5/2 spool valve and 50-VPE 3/2 poppet valve. Certified Ex d Ⅱ BT4, CCC, TIIS & IEC with IPX6 protection, they apply to Zone 1 & Zone 2 flammable and explosive environments such as lithium coating, chemical, painting and oil & gas workshops. Both share interchangeable 3.5W low-power flameproof coils and housings, while their manifold bases are non-interchangeable. 50-VFE requires 0.15MPa differential pressure and only works for positive-pressure double-acting cylinder circuits, incompatible with vacuum. 50-VPE features zero-pressure startup, stable under full vacuum down to -101.2kPa and automatic pressure relief upon power loss for vacuum handling and single-acting cylinders. Lubrication-free design allows single threaded mounting or multi-station manifold valve island assembly with certified flameproof wiring fittings, providing safe standard pneumatic switching for explosion-proof industrial production lines.
