SOLH VG342 is a CE & ASME certified pilot operated poppet 3-port solenoid valve with superior zero-leak sealing and quick response. Equipped with standard 1.3W and energy-saving 0.4~0.55W coils, it supports switchable NC/NO logic without pipe modification, operating stably at 0.1–1.2MPa for compressed air, light oil and neutral inert gas. It adopts AISI 304 stainless steel poppet and ozone-resistant FKM/HNBR seals with built-in inlet filter, allows all-direction mounting and reaches 50-million-cycle service life. Perfectly matched with VBA boosters and VBAT air tanks, it applies to high-voltage switchgears, semiconductor, medical, automotive, petrochemical and precision automation lines, complying with ISO9001, CE, ASME and GB standards.

SOLH CJ1 ultra-miniature pin pneumatic cylinder is interchangeable with equivalent SMC models, offered in φ2.5 and φ4 bore sizes. φ2.5 is single acting spring return only, while φ4 supports both single acting and double acting versions. Slim and ultra-lightweight (2~3.5g), it features no built-in cushion for rapid response. The rod-side air port can be rotated ±90° to facilitate tubing layout. External threads on both ends enable direct axial fixing without extra brackets. It delivers thrust ranging from 0.64 to 6.3 N at 0.5 MPa, suitable for micro loads below 100 g to avoid impact damage to delicate tiny workpieces. NBR seals support oil-free operation for clean environment. Widely applied in short-stroke high-frequency push-pull tasks including 3C button durability testing, chip ejection, micro component positioning, precision instrument fine-tuning and miniature actuators for medical devices. A thrust safety factor of at least 50% is recommended during selection.

JAWS UPSTREAM 250A 3P，The Switchgear Incoming Plug 3P 630A is a robust and efficient solution designed for high-performance electrical distribution systems. Engineered for three-phase applications, this plug ensures seamless connectivity and reliable power transfer in switchgear assemblies. Its 630A rating makes it suitable for industrial settings where substantial electrical loads are common, enabling operations in manufacturing plants, data centers, and large commercial buildings.

Richge is a manufacturer of Electric Interlock Mechanisms in China, specializing in sophisticated solutions designed to enhance the safety and reliability of electrical systems. Our electric interlock mechanisms are engineered to provide precise control and prevent unauthorized or unsafe operations in various switchgear applications.

SOLH VM4 (VM400) medium 3-port poppet mechanical valve is fully interchangeable with equivalent SMC models, positioned between mini VM1 and high-flow VM2 series. Its core advantage lies in compatibility with full pressure range from -100kPa vacuum to 1.0MPa positive pressure, a feature unavailable on VM2. It adopts standard Rc1/8 port with optional NPT/G1/8 threads and Cv=0.38 flow capacity, supporting side and bottom port piping layout. Built with solid metal body, it withstands 1000m/s² impact and heavy vibration, suitable for harsh heavy-duty production lines, with lubrication-free dust-resistant poppet sealing for long service life. A complete set of interchangeable actuators are provided: standard / hardened anti-abrasion steel roller lever, one-way anti-rebound roller, straight plunger, multi-color mushroom emergency stop buttons, 2/3-position rotary knobs, lockable pushbuttons and toggle hinge levers. Widely applied in cylinder & slide table stroke limit detection, vacuum adsorption/release circuits, equipment manual jog commissioning, machine safety emergency interlock and jig fixture switching, it is the ideal medium mechanical trigger valve for working conditions requiring vacuum compatibility and strong shock resistance.
