VCH400 (VCH410) Series High Pressure Pilot Operated 3 Port Poppet Solenoid Valve

Brand: SOLH by Richge Technology 

Product Positioning

     Developed and manufactured by SOLH under Richge Technology, VCH400 series (commonly referred to as VCH410) is a high-pressure pilot-operated 3-port poppet solenoid valve. Specially engineered for medium & high-pressure compressed air and inert gas pipelines, it features a maximum rated working pressure up to 5.0 MPa, outstanding flow capacity and stable high-pressure switching performance, serving as a core control component for high-pressure charging, venting and pressure switching industrial equipment.

Model Coding & Functional Definition

Model Code Example:VCH410-06-5D

     --VCH410: Series base code

     --06: Port size code (G3/4)

     --5D: DC24V power supply + DIN electrical connector Suffix codes cover port size, coil voltage and wiring terminal types for full configuration differentiation.

Functional Classification

     --VCH410 (Normally Closed NC): Output port automatically vents when power off, ideal for main air supply on-off control.

     --Usable as selector valves and charge & vent loop control; back pressure and switching pressure range must be confirmed before piping design.

Key Selection Guidelines

     --Prioritize confirmation of core parameters: working pressure, port thread size, NC/NO function, coil voltage and electrical wiring interface.

     --For high-pressure switching or dual high/low pressure conversion working conditions, match with SOLH VCHR series high-pressure regulators to stabilize intermediate circuit pressure.

     --Require clean dry air supply with filtration precision ≤5 μm; oil mist and particulate impurities will accelerate seal wear and shorten service life drastically.

Installation & Maintenance InstructionsInstallation Rules

     --Forbidden mounting orientation: Coil must never face downward, to avoid dust, water and foreign particles entering the armature assembly and causing jamming.

     --Standard thread tightening torque:

         *G1/2, G3/4 thread ports: 28–30 N·m

         *G1 thread port: 36–38 N·m

Routine Maintenance Requirements

     --Periodically inspect sealing performance and electrical wiring tightness.

     --Actuate full switching cycle once every 30 days to prevent poppet spool adhesion and blockage caused by long-term static state.
