VT317 Series 3 Port Solenoid Valve – Direct Acting Poppet Type

Brand: SOLH by Richge Technology

Product Positioning

     VT317 series is a direct acting poppet 3-port solenoid valve with elastic sealing structure under SOLH standard. Developed for compressed air and inert gas circuits, it realizes air circuit on-off, switching and exhaust control. Supporting zero-pressure startup and both positive pressure & vacuum operation, this compact high-flow general switching valve fits high-cycle working conditions of various automated equipment.

Core Key Features

     --Direct Poppet Construction with Zero-Pressure StartupNo minimum pilot pressure required for operation. Stable performance across full positive pressure range 0–0.9 MPa; vacuum variant supports pressure down to -101.2 kPa, adaptable to low-pressure, vacuum and medium-high pressure working environments.

     --6 Functions Integrated in One Valve, Flexible Piping Switching6 switchable working modes including Normally Closed (NC), Normally Open (NO), flow divider and selector valve. Single unit satisfies diverse pneumatic circuit demands with outstanding configuration flexibility.

     --Compact Body with Superior Flow CapacityMini overall dimension: 45×89.5×45 mm; flow coefficient C=2.6 dm³/(s·bar). Fast response within ≤30 ms and max switching frequency up to 10 Hz, perfectly suitable for high-speed air path switching.

     --Elastic Seal & Lubrication-Free DesignPremium elastic sealing components deliver reliable tightness and extended service life. Lubrication-free operation keeps gas circuits clean and eco-friendly while cutting routine maintenance expenses.

 Built-In Non-Locking Manual Override for Easy CommissioningStandard non-locking manual push button facilitates on-site debugging, equipment inspection and emergency manual switching, simplifying installation and maintenance procedures.

     --Manifold Mountable & Strong CompatibilitySupports manifold stacked assembly and matches standard valve island systems, ideal for centralized pneumatic control and multi-valve integrated loops.
