VEX1 Series High Flow 3-Way Relief Pressure Regulator

Brand: SOLH by Richge Technology

Product Positioning

     VEX1 series is a high-flow, high-precision 3-way relief type pressure regulator developed under SOLH by Richge Technology. It specializes in stable constant pressure maintenance, rapid exhaust and two/multi-stage pressure regulation for heavy-duty pneumatic circuits. It is the mainstream pressure control solution for high-pressure air tanks, high-volume air blowing and large-bore high-power cylinder drive equipment.

Core Product Features 

1. Ultra-High Flow Capacity (Core Competitive Advantage)

     -- Adopts balanced poppet spool structure instead of traditional diaphragm design, featuring large opening stroke and ultra-low flow resistance.

     -- Delivers 3~5 times higher flow rate than ordinary AR series regulators to support instantaneous heavy air supply demand.

     -- Equipped with oversized overflow exhaust port to realize fast pressure relief, stable back pressure and effective suppression of pressure fluctuation.

2. High Precision Pressure Stabilization

     -- Hysteresis ≤ 0.03 MPa

     -- Repeatability ≤ 0.01 MPa

     -- Sensitivity ≤ 0.01 MPa Minimal pressure fluctuation, perfectly suitable for precision constant pressure and constant flow working conditions.

3. Two Optional Control Modes

     -- Air pilot type (VEX1□00): Driven by external pneumatic signal P1, applicable to remote control, explosion-proof workshops and multi-point pressure switching systems.

     -- External solenoid pilot type (VEX1□00+G): Integrated built-in pilot solenoid coil with DC24V / AC220V options to realize automatic electrical pressure switching.

4. Wide Adjustable Pressure Range & High Pressure Resistance

     -- Maximum inlet working pressure: 1.0 MPa

     -- Adjustable set pressure range: Air pilot version: 0.05 ~ 0.9 MPa Solenoid pilot version: 0.05 ~ 0.7 MPa5. User-Friendly Operation & Wide Temperature Adaptation· Free mounting orientation without angle limitation

     -- Fully lubrication-free design, compatible with oil-free dry air circuits

     -- Operating temperature range: 0 ~ 50℃; air pilot model extended to 0 ~ 60℃, anti-condensation performance
