SOLH VM4 (VM400) medium 3-port poppet mechanical valve is fully interchangeable with equivalent SMC models, positioned between mini VM1 and high-flow VM2 series. Its core advantage lies in compatibility with full pressure range from -100kPa vacuum to 1.0MPa positive pressure, a feature unavailable on VM2. It adopts standard Rc1/8 port with optional NPT/G1/8 threads and Cv=0.38 flow capacity, supporting side and bottom port piping layout. Built with solid metal body, it withstands 1000m/s² impact and heavy vibration, suitable for harsh heavy-duty production lines, with lubrication-free dust-resistant poppet sealing for long service life. A complete set of interchangeable actuators are provided: standard / hardened anti-abrasion steel roller lever, one-way anti-rebound roller, straight plunger, multi-color mushroom emergency stop buttons, 2/3-position rotary knobs, lockable pushbuttons and toggle hinge levers. Widely applied in cylinder & slide table stroke limit detection, vacuum adsorption/release circuits, equipment manual jog commissioning, machine safety emergency interlock and jig fixture switching, it is the ideal medium mechanical trigger valve for working conditions requiring vacuum compatibility and strong shock resistance.

SOLH VZM500 5/2‑way mechanical valve is developed with reliable elastic‑seal technology, mass‑produced in‑house with adequate stock. This SMC‑compatible medium‑flow pneumatic control valve supports abundant actuator heads for limit triggering, manual jog and safety interlock. Offering Cv 0.6 flow performance and 300cpm high‑frequency capability, it supports foot‑mount and manifold installation. Oil‑free and zero‑leakage, it serves as standard component for dual‑cylinder synchronization, circuit switching and mechanical limit control across automated production lines.

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 AS series AS2201F elbow meter-out pneumatic speed control valve, fully interchangeable with SMC AS series. One-touch quick fitting, optional S pre-sealed thread and A push-lock anti-vibration handwheel. Supports meter-out / meter-in throttling modes, multiple thread & tube size options, widely used for industrial pneumatic cylinder flow regulation.

SOLH VCC series pneumatic fluid control valve leverages mature PTFE‑diaphragm R&D technology. Manufactured in‑house with accessible stock, it supplies global automotive spraying, lab fluid distribution and chemical‑process end‑users. This pilot‑operated solvent fluid valve delivers zero‑sliding‑friction, low‑residue performance, resisting paints and corrosive solvents. Supporting manifold installation and 5‑million‑plus service cycles, it guarantees intrinsically‑safe medium switching for explosion‑prone coating workshops and precision fluid‑handling facilities.

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 VNA201 is a self-developed standardized 2/2-way external pilot fluid control valve with balanced poppet structure. Driven by 0.2~0.7MPa pilot air, it achieves zero differential pressure startup and bidirectional fluid flow, delivering stable switching under low pressure, vacuum and fluctuating air supply. Optimized internal passages bring large flow capacity and low pressure loss. Equipped with wear-resistant seals and solid valve body verified by million-cycle durability tests, it operates lubrication-free and maintenance-free with anti-fouling performance. Compact lightweight body allows all-angle mounting with 3/8" and 1/2" port sizes, supporting air pilot and solenoid pilot control. Compatible with compressed air, inert gas, light oil and neutral air-liquid mixed fluids, it is widely used for cylinder buffering, cooling lubrication, high-speed exhaust and pipeline on-off of machine tools, packaging & cleaning automation equipment.
