SOLH SY series pilot-operated 5-port solenoid valve is fully interchangeable with matching SMC valves, including SY3000 mini, SY5000 medium mainstream, SY7000 large and SY9000 extra-large models. It provides complete circuit options: 5/2 single/double coil and 5/3 three-position with center closed, center exhaust & center pressure supply functions. Standard 0.35W coils and optional 0.1W ultra-low power energy-saving coils generate little heat for continuous energization. Internal pilot version works 0.1~0.7 MPa, while external pilot variant supports -100kPa vacuum environment. The gap-sealed spool reaches up to 200 million switching cycles. Air ports are arranged on side, top and bottom for flexible tubing routing. Valves adopt plug-in snap design compatible with SS5Y manifold valve islands, enabling single-valve maintenance without disassembling the whole bank, with IP65 plug connector and IP67 manifold base rating. Optimized internal runners deliver around 80% higher flow than legacy valves, and built-in pilot filter mesh prevents spool stuck by dust. Widely used for cylinder directional switching and centralized pneumatic control in semiconductor, automotive welding, packaging and medical automation equipment.

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 2S series 2/2-way normally closed fluid solenoid valves include two full lines: direct-acting small orifice 030/050 models and pilot-operated large bore 150~500 variants, for automatic on-off control of clean water, compressed air, cutting coolant, lubricating oil and weakly corrosive liquid pipelines. The direct-acting version enables zero-pressure startup without minimum differential pressure limit, features compact size, universal mounting orientation and millisecond fast switching, ideal for low-pressure micro-flow applications such as single-point machine tool cooling, 3C micro air/water branches and mini cleaning equipment. The pilot-operated type requires a minimum 0.05MPa pressure difference for full opening, delivers ultra-large flow with low-wattage low-heat coils, suited for air compressor drain headers, main spray water lines and high-flow circulating water treatment pipelines. Standard NBR nitrile rubber seals are equipped, with optional acid & hot water resistant EPDM food-grade seals. Multi international thread standards (PT/G/NPT) and global universal coil voltages (DC12/24V, AC24/110/220V) are available, supported by DIN plug and wire lead wiring options. Heat-resistant coils allow long-term continuous energization. Selection guide: direct-acting type for pipelines with static pressure below 0.05MPa and small branch flow; pilot-operated version for G1/2 and above main headers with stable high pressure & large circulation flow. EPDM seal is mandatory for hot water and food-grade fluid media.

SOLH 2W series 2/2-way normally closed fluid solenoid valve with solid brass body includes small orifice direct-acting 030/050 models and large bore pilot-operated 150~500 variants, designed for automatic on-off control of clean water, compressed air, cutting coolant, lubricating oil and weakly corrosive fluid pipelines. The direct-acting version realizes zero differential pressure startup with no minimum working pressure limit, features compact size, universal mounting orientation and millisecond high-frequency switching, ideal for low-pressure micro-flow branches, vacuum auxiliary water circuits and single-point cooling for small machine tools. The pilot-operated type requires a minimum 0.05MPa startup differential pressure, delivers ultra-large flow with low-power low-temperature-rise coils, suited for air compressor main drain lines, general assembly main spray water circuits and high-flow circulating pipelines for water treatment systems. Standard NBR nitrile rubber seals are equipped, with optional heat & acid resistant EPDM food-grade seals. Multiple international thread standards (PT/G/NPT) and full-range coil voltages (DC12/24V, AC24/110/220V) are available, supported by DIN plug sockets for cabinet wiring and IP65 waterproof wire leads for humid outdoor equipment. Heat-resistant coils allow 24-hour continuous energization without burnout. Selection guidelines: choose direct-acting type for pipelines with static pressure below 0.05MPa and micro single-point flow; select pilot-operated variant for G1/2 and above main headers with stable high-pressure large circulation. EPDM seal is mandatory for hot water, purified water and food-grade fluid media.

Developed with optimized poppet‑sealing technology, SOLH VG342 pilot‑operated poppet solenoid valve is mass‑produced in‑house with sufficient stock. Serving global automation end‑users, this high‑flow vacuum compatible solenoid valve supports NC/NO/external‑pilot conversion. It delivers large‑capacity airflow, 1.8W low‑power option and 5Hz high‑frequency cycling. Oil‑free and zero‑leakage, it acts as reliable manifold main control valves for vacuum holding systems, large‑bore actuators and multi‑loop pneumatic automation lines.

SOLH VEX1 balanced poppet 3-way relief pressure regulator adopts poppet structure instead of traditional diaphragm design, delivering 3~5 times higher flow than standard AR regulators with oversized relief port for fast pressure relief and stable back pressure. It achieves superior regulation precision with hysteresis ≤0.03MPa, repeatability & sensitivity ≤0.01MPa.

SOLH SCV series dedicated air-operated coating valves include 2-way SCV12 and 3-way SCV13 for paint, thinner and purge air switching & fast color change control. Wetted parts adopt composite PTFE+FPM solvent-resistant seals, and isolation diaphragm separates driving mechanism from coating liquid to avoid paint adhesion, achieving service life over 5 million cycles. Fully pneumatic structure without electric parts eliminates spark risks for explosion-proof coating workshops. Matched manifold base supports centralized control of up to 15 colors; optimized internal flow channel cuts thinner consumption during flushing and prevents cross-color contamination. Available for single standalone mounting or dense manifold stacking, widely applied in auto, furniture, hardware & home appliance automatic coating color change systems, solvent circulation cleaning and spray gun purge air circuits.

SOLH VEX1133 high-flow precision relief regulator adopts combined nozzle-flapper pilot and balanced poppet structure. Compact in size yet with strong supply & exhaust capacity, it realizes ultra-fast pressure stabilization with negligible overshoot under sudden load changes and large downstream volume. It delivers ultra-high control precision with sensitivity ≤0.2% FS and repeatability ≤±0.5% FS, fully meeting micron-level positioning and constant force/tension process standards. Built-in overflow relief automatically discharges excess pressure inside closed air chambers to maintain stable set pressure without drift.
