It is an ideal micro pneumatic control solution for precision automation, miniature jigs and space-limited equipment.

SOLH ARJ310 series direct-acting relief miniature pressure regulator is fully interchangeable with SMC equivalent models, designed for low-flow and space-limited precision pneumatic control. With an ultra-compact 18.5mm narrow body and 65g lightweight design, it supports dense manifold stacking. Featuring dual M5 and Rc1/8 inlet threads and integrated outlet push-in fittings for fast installation, it provides dual pressure ranges of 0.05–0.7MPa with built-in overpressure relief for stable output pressure. Suitable for panel and bracket mounting, it is widely used in electronics assembly, medical devices, semiconductor inspection and miniature precision automation equipment.

SOLH ARX series compact piston pressure regulators support a maximum inlet pressure of 2.0MPa, breaking the pressure limit of ordinary miniature regulators. Available in standard high-pressure and low-precision pressure models, it features zero steady air consumption for excellent energy-saving performance and doubled flow capacity compared with similar-sized products. Ultra-light at 110g with triple output ports for flexible multi-channel piping layout, it reserves a gauge port and supports multi-directional installation. Adopting a built-in relief and lubrication-free structure, it delivers stable maintenance-free operation, ideal for high-pressure compact pneumatic equipment, precision blowing, fluid dispensing and laboratory pressure testing systems.

SOLH WR110 series is a compact brass water pressure regulator specially designed for industrial cooling water and process water pipelines. Adopting anti-scale and anti-corrosion brass construction, it fits tap water and general industrial water working conditions. With dual adjustable pressure ranges and a maximum working pressure of 0.8MPa, it features built-in overpressure relief for stable water pressure and pipeline protection. Equipped with a lockable knob, reserved gauge port and diverse mounting options, it delivers fast response and minor pressure fluctuation. It is widely used in machine tool cooling, laser equipment, water treatment, instrument water supply and industrial spraying circulation systems.

SOLH AP100 series direct spring compact relief valve is developed for upper-limit pressure stabilization and overpressure protection of miniature pneumatic circuits. Lightweight at only 0.12kg, its tiny outline fits embedded narrow equipment. It adopts tool-free lockable adjustment knob to avoid pressure drift from vibration. Two pressure ranges are available: standard 0.05–0.69MPa and low-pressure 0.02–0.2MPa, with 1.0MPa max working pressure and fast large-flow pressure relief. Die-cast aluminum body supports Rc, NPT and G threads for direct thread mounting or bracket installation. Widely applied in 3C & medical compact jigs, cylinder buffering, downstream regulator overload protection and laboratory constant pressure limit pipelines.

Custom SOLH XT92-51-X2 precision pressure detection valve is tailor-made for UTC, functionally different from ordinary precision regulators and dedicated to pressure threshold trigger, low-pressure safety interlock and dual-circuit pneumatic signal switching. With direct-acting structure and adjustable switching pressure from 0.1~0.5MPa, it is fully compatible with SMC pipe fittings and supports bracket & panel mounting. It automatically switches air paths above and below preset threshold with built-in silencer exhaust port, replacing combined pressure switch and solenoid valve to simplify air circuits. Widely used in equipment low-pressure interlock, dual air supply switch and startup pressure permission control, it only works for pneumatic signal detection instead of continuous pressure regulation.

SOLH IR412-04-X32 pilot operated precision regulator is fully interchangeable with SMC equivalent models. Adopting nozzle-flapper relief structure with Rc 1/2" main port, this X32 customized rear exhaust version features adjustable pressure range of 0.01~0.7MPa and ultra-high sensitivity of 0.2% full scale, with steady air consumption less than 1 L/min. It boasts remarkable flow and relief performance, while rear exhaust design avoids dust and oil mist pollution. Available with panel or bracket mounting and optional front/rear pressure gauge, it provides ultra-stable pressure output for precision dispensing, lithium battery film tension control, large-bore cylinder positioning and semiconductor cleanroom pneumatic systems.

SOLH VP series CE certified pilot large-size 3-port solenoid valve features ultra-high flow with port sizes from Rc 3/8" to 1-1/2" and max Cv up to 7.0. Three grades of energy-saving coils (1.55W/0.55W/0.4W) are optional, with switchable NC/NO function without pipe modification, supporting 0~1.0MPa positive pressure and -101.2kPa vacuum conditions. Equipped with ozone-resistant HNBR main seals, FKM pilot seals and built-in dust filter, it allows arbitrary mounting and delivers a 50-million-cycle service life. Perfectly matched with VBA boosters and VBAT air tanks, it also fits heavy cylinders, vacuum fixtures, electrical cabinets, automotive & packaging machinery. Certified with CE, ASME, GB and ISO9001, it is an ideal heavy-duty switching valve for industrial pneumatic boosting and automation systems.

SOLH VG342 is a CE & ASME certified pilot operated poppet 3-port solenoid valve with superior zero-leak sealing and quick response. Equipped with standard 1.3W and energy-saving 0.4~0.55W coils, it supports switchable NC/NO logic without pipe modification, operating stably at 0.1–1.2MPa for compressed air, light oil and neutral inert gas. It adopts AISI 304 stainless steel poppet and ozone-resistant FKM/HNBR seals with built-in inlet filter, allows all-direction mounting and reaches 50-million-cycle service life. Perfectly matched with VBA boosters and VBAT air tanks, it applies to high-voltage switchgears, semiconductor, medical, automotive, petrochemical and precision automation lines, complying with ISO9001, CE, ASME and GB standards.
