China low pressure vacuum solenoid valve Manufacturer, Supplier, Factory

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.

SOLH KQ2Z multi-port manifold push-in fittings, SMC KQ2Z equivalent pneumatic splitter. Four sub-types: 1-in-2, stackable KQ2ZF, 1-in-4 KQ2ZD and 1-in-6 KQ2ZT. PBT body with nickel-plated brass thread, compatible with PU/PA tubes for vacuum & positive pressure circuits. Richge Technology offers stable stock and reliable manufacturing for automation air distribution.

SOLH KQ2U and KQ2UD are Y-style multi-port push-in manifold connectors within the KQ2 pneumatic fitting family, direct replacement for SMC KQ2U / KQ2UD. KQ2U is a 1-in 2-out Y splitter, and KQ2UD is a compact 1-in 4-out air distributor. Available in male thread, equal-diameter and reducing versions. Constructed with PBT body and NBR sealing, these quick push fittings support both compressed air and vacuum systems. Widely used for centralized air supply for vacuum cup arrays, multi-cylinder automation fixtures, 3C and packaging machinery.

The Switchgear Panel Connection Kit is an essential component designed to facilitate the seamless integration of switchgear panels in various electrical systems. This kit includes a comprehensive set of connection components such as terminal blocks, mounting brackets, and high-quality connectors that ensure reliable and efficient panel assembly and connection.

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.
