VEX1133 Series High Flow Precision Relief Regulator

Brand: SOLH by Richge Technology 

Product Positioning

     SOLH VEX1133 series is a high-flow, high-precision relief-type precision regulator adopting balanced poppet structure matched with nozzle-flapper pilot mechanism. It delivers outstanding supply and exhaust capacity within a compact footprint while maintaining ultra-stable pressure control accuracy. Custom-designed for precision pneumatic circuits demanding large flow and minimal pressure fluctuation, it acts as a core pressure adjustment component for high-end working conditions including pneumatic balancers, tension control, precision positioning and heavy pneumatic actuation equipment.

Core Key Features

1. High Flow & Large Relief Capacity for Ultra-Fast Pressure Stabilization

     Built with balanced poppet design to deliver equally powerful air supply and exhaust performance. Even with large secondary-side volume and sudden load changes, the regulator responds instantly to stabilize pressure with nearly zero overshoot and pressure fluctuation.

2. Ultra-High Precision Pressure Control

     Sensitivity ≤ 0.2% F.S.; Repeatability ≤ ±0.5% F.S. Extremely accurate pressure setting and excellent long-term stability, fully meeting the requirements of micron-level positioning and constant force control processes.

3. Built-In Relief Structure for Steady Constant Pressure

     Integrated overflow relief function automatically releases excess secondary-side pressure once overshoot occurs, locking pressure at the target value without drift. Ideal for constant pressure maintenance of closed chambers and sealed air cavities.

4. Compact Robust Structure with Extended Service Life

     Friction-free internal moving parts, fully lubrication-free and anti-contamination design; control accuracy will not degrade after long-term continuous operation. Supports mounting at any angle for flexible on-site layout design.

5. Wide Compatibility & Easy System Integration

     Available as standalone single unit or manifold modular stacked assembly, perfectly compatible with automated production equipment, precision testing instruments and high-end pneumatic control platforms.
