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.

SOLH VT307 is a compact direct-acting 3-port poppet solenoid valve with elastic rubber seal. It realizes zero-pressure startup and stable operation under 0–0.7MPa positive pressure or full vacuum down to -101.2kPa. Optional NC, NO, flow division and selection functions are available, with response time ≤20ms and max switching frequency up to 10Hz. Lubrication-free soft seal and built-in manual override simplify on-site debugging, and its mini body supports manifold stacking installation. Widely used in automated assembly, robots, vacuum suction jigs, blowing stations, packaging, printing and food machinery, it adopts imported core parts and serves long-term clients including Foxconn, Huawei, Midea and Gree.

SOLH VO307 manifold-mount 3-port direct acting poppet solenoid valve is tailor-made for valve islands and matched with VV307 series manifold bases.
