China SOLH VH series Manufacturer, Supplier, Factory

SOLH XSA normally closed solenoid valve is specially designed for ultra-high vacuum circuits for air and inert gas, supporting ultimate vacuum down to 1×10⁻⁶ Pa with ultra-low internal and external leakage rates. Its built-in internal spring minimizes friction and particle generation to meet strict cleanroom standards. Featuring lower coil power consumption and lighter body for easy compact integration, it provides multiple connection options including face seal, ferrule and internal Rc/NPT thread, with complete mainstream voltages and wiring terminals. Certified CE & RoHS, it serves as reliable core switching component for semiconductor, PV, LCD, medical sterilization, food vacuum packaging and laboratory ultra-high vacuum testing equipment.

SOLH MHS3 3-jaw and MHS4 4-jaw wedge-cam self-centering hollow pneumatic grippers are fully interchangeable with equivalent SMC models. Wedge cam transmission drives synchronous jaw centering, achieving repeat positioning accuracy of ±0.01 mm. Bore sizes range from 16 to 125 mm. Standard double acting (D) design, with optional single acting normally closed (C) / normally open (E) spring return versions. The central hollow through hole allows routing of air tubes, ejector pins and optical fibers, supporting both external clamping and internal expanding gripping. Evenly spaced three jaws of MHS3 provide superior coaxiality, ideal for shafts, discs and ring-shaped workpieces. Orthogonally arranged four jaws of MHS4 deliver stable constraint for square, rectangular and irregular flat parts to avoid tilting. Built-in permanent magnets are compatible with M9BW series magnetic switches. The low-profile compact body fits robot end effectors perfectly. Derivative variants include dust-protected MHSJ3 and extended hollow MHSH3. Widely applied to machine tool loading/unloading, bearing press-fitting, handling of 3C circular & square components and concentric assembly of tubular workpieces.

SOLH HFR pivot-linkage 180° wide-opening pneumatic gripper is driven by piston linkage to rotate jaws. Each jaw swings up to 90°, forming a straight line when fully opened to provide maximum clearance and eliminate mechanical interference during pick-and-place. Bore sizes cover 10/16/20/25/32 mm with purely double acting design. The -2°~-5° overclose angle ensures stable clamping. Three mounting surfaces (side, bottom, rear) are available; locating pin holes on the base improve assembly accuracy, and suffix-N through-hole mounting is optional. All models come with built-in permanent magnets and sensor grooves compatible with CMSH magnetic switches. Optimized dust-proof jaw structure and anti-friction metal separators deliver service life over 5 million cycles for moderately dusty workshop environments. Widely used for gripping and turnover of deep-cavity workpieces, large plastic housings and box materials. MHW2 gear-driven swing gripper can be considered for medium-load applications if extreme avoidance clearance is unnecessary. A minimum 30% safety margin must be reserved during torque calculation; extended jaw overhang greatly reduces effective clamping torque.

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 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 IR series precision pilot regulators adopt advanced nozzle-flapper internal pilot structure, delivering 0.2% ultra-high control accuracy and excellent repeatability. It stably maintains output pressure against air source fluctuation and dynamic load changes. Featuring high flow rate, fast response and ultra-low air consumption of 1–3 L/min for significant energy savings, it supports manual adjustment and pneumatic remote control. Compact and flexible with built-in overpressure protection, it is widely used in semiconductors, precision testing, tension control, medical instruments and high-end precision automation systems.
