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. Featuring friction-free internal components, lubrication-free and anti-contamination design, it allows arbitrary-angle mounting and supports standalone or manifold stacked assembly. Widely applied to film & wire tension control, pneumatic balancers, precision press-fit machinery and laboratory test bench constant pressure systems.

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.
