SOLH VNA201 is a self-developed standardized 2/2-way external pilot fluid control valve with balanced poppet structure. Driven by 0.2~0.7MPa pilot air, it achieves zero differential pressure startup and bidirectional fluid flow, delivering stable switching under low pressure, vacuum and fluctuating air supply. Optimized internal passages bring large flow capacity and low pressure loss. Equipped with wear-resistant seals and solid valve body verified by million-cycle durability tests, it operates lubrication-free and maintenance-free with anti-fouling performance. Compact lightweight body allows all-angle mounting with 3/8" and 1/2" port sizes, supporting air pilot and solenoid pilot control. Compatible with compressed air, inert gas, light oil and neutral air-liquid mixed fluids, it is widely used for cylinder buffering, cooling lubrication, high-speed exhaust and pipeline on-off of machine tools, packaging & cleaning automation equipment.

Cable Assembly for Switchgear Product Background: Richge is a manufacturer of Cable Assemblies for switchgear in China, specializing in the design and production of high-quality, reliable cable solutions for electrical systems.

Meeting industry standards for performance and safety, our board bases are ideal for a range of switchgear applications, providing robust solutions for maintaining the integrity and efficiency of electrical systems.

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.
