SOLH 4A series 5/2-way and 5/3-way air-operated directional control valves are the full pneumatic counterpart of the classic 4V electromagnetic solenoid valve series. Driven entirely by external pneumatic control signals with no coils or electrical parts inside, this valve achieves inherent explosion-proof safety and serves as the core control unit for non-electric pneumatic loops, hazardous explosive areas and safety interlock systems. It adopts high-precision spool configuration and robust aluminum alloy housings, sharing identical installation dimensions and flow characteristics with the 4V series for seamless direct replacement and upgrade between electric-driven and full-pneumatic control schemes. The standard five-port layout follows industry universal specifications: P for main air supply inlet, A and B as working ports connected to two chambers of double-acting cylinders for extension and retraction regulation, R and S as exhaust ports compatible with standard silencers to reduce operational noise. The 5/2-way lineup supplies single pneumatic control and double pneumatic control options. Single air-controlled models switch upon receiving control air signals and automatically reset by built-in springs once the control pressure disappears to deliver fail-safe protection. Double air-controlled variants feature no return springs and lock the current spool position persistently after control air is disconnected, supporting long-duration positioning and pressure retention without sustained control air input. 5/3-way versions are exclusively double air-driven with three selectable neutral configurations: closed center (Type C) seals all ports to lock cylinders and prevent vertical falling; exhaust center (Type E) vents A/B ports to atmosphere for pressure release and manual commissioning; pressure center (Type P) feeds compressed air to both working ports for synchronous clamping and force balance adjustment. Suitable for filtered compressed air within 0.15~0.8 MPa working pressure, the whole series supports lubrication-free operation and works reliably from -20℃ to +70℃. Widely applied in chemical plants, painting workshops, mining and other explosion-risk environments, it cooperates with mechanical valves, hand-operated valves and air pilot valves to build complete all-pneumatic logic control systems for double-acting cylinders.

SOLH CJ2K stainless steel non-rotating mini cylinder belongs to the CJ2 cylinder family and features full dimensional interchangeability with imported original CJ2K. Bore sizes cover Φ10 and Φ16. Equipped with hexagonal piston rod and built-in guide structure for mechanical anti-twist performance. Rotation tolerance: ≤±1.5° for Φ10 and ≤±1° for Φ16, eliminating load deflection issues occurring on ordinary round rod cylinders during reciprocation. Constructed with 304 stainless steel barrel for rust and moisture resistance, featuring slim and compact outline. Three operation modes are optional: double acting, single acting spring return and single acting spring extend. Built-in magnetic ring is optional, compatible with M9BW magnetic switches for position feedback. Standard rubber cushions at both ends; oil-free operation supported with mechanical service life up to 8 million cycles. Multiple mounting options are available including basic type, foot mount, flange mount and double clevis mount. Ideal for applications requiring fixed angular posture of end fixtures, such as flat jig pushing in 3C automation, linear feeding of cameras for optical inspection, workpiece transportation inside guide slots and ejection of flat workpieces. Standard CJ2 round rod cylinder is recommended if angular restriction is unnecessary and cost efficiency is prioritized. Excessive radial side load on piston rod should be avoided to prevent guide bushing abrasion and deterioration of anti-rotation accuracy.

SOLH MXS high-rigidity integrated pneumatic slide table is fully interchangeable with SMC MXS series. It adopts dual-piston driving and preloaded cross roller guide rails for zero-clearance movement, delivering twice the thrust of single-cylinder slides with the same bore and repeat positioning accuracy up to ±0.01mm. The ultra-thin integrated structure saves 30%~50% installation space compared with split cylinder plus external guide sets. Three-sided mounting with positioning pin holes (bottom, side and axial) is supported. Bore sizes φ6~25mm with standard strokes 10~150mm, optional 0~5mm stroke adjusters. Built-in magnet fits magnetic switches and enables oil-free operation. Widely used for high-rigidity, high-precision linear transfer in semiconductor, 3C precision assembly and optical component alignment stations.

KQ2C push-in caps are dedicated tube plugs for SOLH KQ2 one-touch pneumatic fittings, engineered as drop-in alternatives to SMC KQ2C. Featuring tool-free insertion, the caps lock into unused push-in ports to achieve reliable sealing for both vacuum and compressed air circuits. Constructed with PBT body and NBR sealing ring, they cover sizes Φ2 through Φ16. Widely used for equipment commissioning, manifold spare port closure and temporary circuit isolation in automation machinery, valve islands and vacuum systems.
