China Vertical Busbar Switchgear Manufacturer, Supplier, Factory

SOLIH AR series pneumatic pressure regulator, modular compressed‑air pressure reducing valve for FRL assembly. Overflow‑type relief structure, self‑locking anti‑loosening knob, die‑cast aluminum body, built‑in pressure gauge port, optional bracket mounting. Models AR1000–AR5000 with M5–1" ports, pressure range 0.05–0.85 MPa, ideal for cylinder, solenoid valve and workshop pipeline pressure stabilization.

The Switchgear Bus Support Insulator is a critical component designed to ensure the reliable and efficient operation of electrical switchgear systems. This high-quality insulator is engineered to provide robust support and electrical insulation for busbars, which are essential for distributing electrical power within switchgear assemblies.

VS1-12 Indoor High Voltage Vacuum Circuit Breaker is three-phase AC 50Hz, rated voltage of 12KV indoor device. For industrial and mining enterprises, power plants and substations as electrical equipment control and protection purposes, and for frequent operation of the place.Because of the special superiority of vacuum circuit breaker, especially suitable for applications that require frequent operation at rated operating Current or multiple open short-circuit breaking current location. It 1s especially suitable to the place requiring frequent operations.

SOLH 3V series 3/2-way pneumatic solenoid directional control valves are engineered with both direct-acting and pilot-operated structures, tailor-made for driving single-acting spring return cylinders and switching vacuum pneumatic circuits. Available in Normally Closed (NC) and Normally Open (NO) configurations, this series adopts high-strength lightweight aluminum alloy valve bodies with compact layout, rapid response and IP65 dustproof & waterproof protection grade, acting as the standard core control component for small and medium-sized pneumatic automation systems. The port layout follows universal industry standards: P for main air inlet, A for execution working port connecting cylinders or vacuum suckers, R for exhaust port matched with silencers to lower operational noise. Direct-acting 3V1 and 3V2 variants support reliable zero-pressure startup within 0~0.8 MPa with switching response under 0.05s, perfectly fit for low-pressure gas pipelines and negative-pressure vacuum control scenarios. Pilot-operated 3V100/3V200/3V300 series features larger flow capacity and lower coil power consumption, requiring a minimum inlet pressure of 0.15 MPa for stable switching to satisfy high-flow conventional pneumatic loops. Equipped with a thimble-style manual override button for convenient on-site debugging during installation and maintenance, the whole series supports oil-free operation with stable sealing performance. Multiple thread specifications including M5, G1/8, G1/4 and G3/8 are optional, paired with mainstream global AC & DC voltages and two wiring modes of DIN socket and flying leads. It can directly replace traditional 3A air pilot valves and 3L hand pull valves without structural modification, widely deployed in workpiece clamping jacking mechanisms, vacuum adsorption switching, pneumatic interlock protection and inching control of small actuators.
