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.

SOLH XTO674 and INA14 inline check valves share the same structural platform with ultra-low 0.01MPa cracking pressure, compatible with both compressed air and clean water for anti-backflow protection in vacuum and low-pressure fluid pipelines. XTO674 is an all-brass cryogenic version working down to -30℃; INA14 standard series provides brass or SUS304 stainless steel body, equipped with standard NBR seals plus optional oil & high temp resistant FKM and weather-proof CR seals. Compact inline threaded design with flow arrow marking can be directly mounted in pipelines without extra brackets, effectively preventing vacuum loss and reverse airflow when installed between vacuum generators and suction cups. The two series feature identical overall dimensions and thread sizes for direct field interchange without pipe modification, widely applied in cryogenic equipment, vacuum production lines, corrosion-resistant high-temperature fluid circuits and general pneumatic & water pipelines for one-way pressure retention and backflow prevention.

LW-126 type outdoor high voltage alternating current sulfur hexafluoride circuit breaker (hereinafter referred to as the circuit breaker) is a kind of outdoor high-voltage switchgear equipment with three poles AC SOHzand it adopts SF6 gas as arc extinguishing and insulation medium. It can be used for the separation and combination of rated current and fault current, capacitor bank, and switching circuit, and it can also be used as aninterconnecting breaker so as to realize the control and protection of transmission lines and equipment, especially suitable for frequent operation.The circuit breaker is equipped with CT20 type spring operation mechanism.This circuit breaker complies with the requirements of IEC 62271-100. Lw36-126 3150-40 self-energized Ac high-voltage sulfur hexafluoride circuit breaker is an outdoor product, suitable for altitudes not exceeding 2,ooo meters (products can be designed for altitudes above 3,ooo meters), and the ambient temperature is not lower than -40°c. In the Ac 50Hz power grid with a maximum voltage of 126KV in areas with a pollution level no higher than Level Iv, it is used to cut off rated current, fault current or conversion lines to achieve power control.For system control and protection, it can also be used as a contact circuit breaker This product uses sF6 gas as arc extinguishing and insulating medium, adopts the most advanced self-energy arc extinguishing technology in the world, and is equipped with a new spring operating mechanism. It has the characteristics of long electrical life, low operating power, low noise, and high reliability., with its simple structure, small size and long maintenance cycle, it can completely replace the same type of imported products in the current process of oil-free and large-capacity power equipment.
