SOLH VR51 all-pneumatic two-hand safety interlock valve complies with EN ISO 13851 and EN574 safety standards. It integrates built-in 0.5-second synchronous detection anti-cheat logic; output air only activates when two buttons are pressed within 0.5s time difference, and air supply cuts off instantly once any button is released to avoid hand crushing injuries. Fully pneumatic without electrical components, it delivers intrinsic explosion-proof performance for dusty, humid and flammable workshops. The 3/2-way logic valve comes with standard exhaust silencer and wear-resistant lubrication-free spool for long service life. Equipped with φ6 / 1/4" flame retardant push-in fittings and optional mounting bracket, supporting rear or bottom piping layouts, it serves as standard safety interlock component for punching, riveting, cutting, injection molding and other high-risk processing machinery.

Whether customers choose air-insulated or gas-insulated switchgear depends on the application as well as on some aspects such as the initial investment cost, total cost of ownership, available space and location (ie. altitude, dust, etc.). We encourage you to get in touch with our sales experts to get the right advice. The GIS circuit breaker is used for gas insulated switchgear, uses splint structure. Its easy to install, reliable breaking performance, long mechanical life and no maintenance. It is substitute for vacuum circuit breaker used in inflatable cabinet. The product performance met standard of GB1984-2014 E2-M2-C2 circuit breaker requirement.

Switchgear Lever: Product Details and Applications The Switchgear Lever is an essential mechanical component in electrical switchgear systems, designed to facilitate the operation of various switching and control mechanisms within the panel. Typically made from high-strength stainless steel or durable alloys, these levers are engineered to withstand the demands of industrial environments, offering both resilience and reliability in critical electrical operations.

SOLH ASV series 4-in-1 quick exhaust throttle valve, fully interchangeable with SMC ASV. Integrates quick-exhaust, throttling adjustment, built-in silencer and one-touch fitting. 2× flow area, push-lock anti-vibration knob, UL94 V-0 flame-retardant housing. Elbow and T-straight styles available, ideal for high-speed, high-frequency low-noise pneumatic cylinder automation systems.

SOLH MG series stainless steel mini pneumatic cylinders are engineered in compliance with JIS industrial standards, offering cost-effective alternatives to SMC CM2 & CM3 series with full dimensional interchangeability for direct replacement and production line retrofitting. Constructed with SUS304 stainless steel barrel and piston rod paired with high-strength aluminum end caps, they deliver outstanding rust resistance against high humidity, dust, weak acid and weak alkali surroundings, perfectly suited for food, pharmaceutical and packaging automation. Rivet rolling crimping secures the barrel and end caps tightly for excellent anti-vibration stability during long-term high-frequency reciprocation. A complete lineup covers standard double-acting, spring single-acting power-off reset types, synchronous double-rod variants and upgraded models with manually adjustable air cushions to suppress impact and noise in high-speed cycles. Low-friction composite sealing with built-in oil storage grooves supports oil-free maintenance-free operation for over 8 million working cycles. Every unit comes pre-installed with a built-in magnetic ring compatible with SMC M9B and Airtac CS1-G sensors to realize real-time position feedback and PLC automated linkage control. Supported by steady mass production and adequate overseas spot inventory, these cost-efficient cylinders are widely deployed in medium-grade automated equipment operating in damp and mildly corrosive workshop environments.
