SOLH 4M series plate-type 5/2-way solenoid valves strictly comply with international NAMUR mounting standards, purpose-built for direct assembly onto pneumatic actuators driving ball valves and butterfly valves. The integrated bottom base comes with pre-embedded P, A, B, R1 and R2 air passages, enabling seamless docking with actuator air cavities without external tubing for A/B working ports. This streamlined layout drastically cuts pipeline layout workload and potential air leakage points compared with conventional tube-connected 4V series solenoid valves. This lineup adopts internal pilot spool construction with oil-free operation, offered in single-coil spring reset (4M×10) and double-coil latching memory (4M×20) configurations covering three size grades: 4M100, mainstream 4M200 and high-flow 4M300. Single electric control variants automatically reset under spring tension once power is disconnected for fail-safe reset scenarios, while double electric control versions retain their switching position steadily after power cut to sustain valve opening/closing status for long-term pipeline locking. Each unit is fitted with a side-mounted manual override button for convenient offline commissioning and maintenance testing. Coils support widely used global AC/DC voltages with IP65 dustproof and waterproof ingress protection, suitable for rigorous working conditions in water treatment, chemical pipelines and general industrial fluid switching. The series is dimensionally compatible with manifold bases shared with the equivalent 4V series, supporting standalone actuator installation or centralized valve island assembly via multi-station manifolds. With certified standard NAMUR interface, interchangeable with mainstream Airtac 4M series, it serves as a dedicated matched control component for automated on-off regulation of pneumatic ball and butterfly valve actuators.

SOLH ITV high flow electro-pneumatic proportional valve is fully interchangeable with equivalent SMC models. Adopting closed-loop pressure feedback system, it accepts DC0–10V voltage, 4–20mA current analog signals, and optional fieldbus communication including CC-Link, PROFINET, EtherNet/IP to achieve stepless, high-precision remote air pressure regulation with ±1% FS control accuracy and IP65 dust & splash-proof protection. Three series cover different flow ranges: ITV1100 for micro low flow, ITV2100 for universal medium flow and ITV3100 for heavy high flow up to 4400 L/min ANR, with adjustable pressure from 0.005 to 0.9 MPa. It supports Rc/NPT/G threads and push-in fittings, built-in LED digital display and self-diagnosis alarm under DC24V low power supply. Widely applied for large bore cylinder actuation, film & wire constant tension control, semiconductor & optical precision processes, automatic dispensing & coating, multi-stage pressure switching for welding and riveting equipment, replacing multiple manual regulators to realize digital centralized pressure control on automated production lines.

SOLH CRA1 rack and pinion rotary cylinders are high-torque pneumatic swing actuators for 10–50kg medium & heavy-duty automation. Dual-piston rack-pinion transmission achieves backlash ≤1°, with φ30 model zero backlash and maximum 108N·m torque from φ100 bore at 0.5MPa. Optional adjustable end air cushions mitigate inertial impact during frequent cycling, while multiple mounting types and shaft configurations support flexible mechanical connection. Oil-free construction ensures low-maintenance continuous operation. Our factory runs stable mass production with ample spot inventory, widely deployed for heavy workpiece flipping, industrial valve actuation, heavy fixture indexing and robotic joint rotation across automated assembly and pipeline control systems.

SOLH TR twin shaft cylinder is manufactured in accordance with JIS industrial standards. It adopts a single-piston dual guide shaft structure matched with extended slide bearing bushes, featuring high structural rigidity, excellent torsion resistance and strong anti-deflection capacity superior to cost-effective TN twin shaft cylinders. Bore sizes range fully from φ6 to 32 mm, including standard single-rod TR, double through rod TRW and lightweight compact TRJ variants. Anti-rotation accuracy reaches ±0.1° for bores ≥16 mm and ±0.2° for φ6/φ10 small bores; dual shafts restrict swinging deviation to guarantee stable operation over long strokes. An adjustable front rubber cushion pad cooperates with fixed rear buffer for stroke trimming, impact absorption and noise reduction. Three-way mounting (top, bottom, side) and optional dual-side porting are available; side grooves allow direct assembly of magnetic switches without extra brackets. Built-in magnetic rings marked suffix S are standard, while non-magnetic customized versions are offered for magnetic interference sensitive occasions. Operating pressure ranges 0.15~1.0 MPa with working temperature from −20℃ to 70℃. Standard Rc thread can be converted to G thread or NPT thread for overseas engineering projects. Distinguished from CXS twin cylinders: TR outputs single thrust with prominent mechanical rigidity and stable side-load resistance in long-stroke applications; CXS features dual pistons for double thrust, lower friction and smoother high-speed reciprocation suited for high-frequency short-stroke pick-and-place. Widely applied in precision positioning, workpiece pressing, long-distance stopping & transfer and general automation stations requiring reliable guiding under medium-light loads.
