VS3135 Series 3 Port Direct Acting Solenoid Valve/ Metal Seal Type

Brand: SOLH by Richge Technology 

1. Product Positioning

     The SOLH VS3135 Series is a high-performance direct-acting 3-port solenoid valve featured with full metal sealing structure. Specially designed for compressed air and inert gas circuits, it realizes precise air circuit on-off, directional switching and exhaust control. Supporting stable zero-pressure startup, it performs reliably under vacuum, low-pressure and high-pressure working conditions. As a durable and cost-effective pneumatic control solution, VS3135 is widely applied for standard and high-end automated production line pneumatic systems.

2. Core Product Advantages

-- Direct Acting Structure with Zero-Pressure Startup

     Requires no minimum startup pressure, operating stably across the full 0–1.0 MPa pressure range. It perfectly adapts to vacuum, low-pressure and high-pressure pneumatic systems with consistent and stable switching performance.

-- Premium Metal Seal Structure, Dust-Proof & Ultra-Long Life

     Adopts industrial-grade metal sealing technology with integrated dust-proof design. Wear-resistant and anti-pollution capability effectively resists workshop dust and impurity interference. Fully lubrication-free design lowers maintenance frequency and extends service life significantly.

-- Fast Response & High-Frequency Durability

     Optimized direct-acting mechanical structure delivers rapid response and stable high-cycle performance. Ideal for high-speed air blowing, fluid jetting, cylinder clamping and other high-frequency switching working scenarios.

-- Superior Shock & Vibration Resistance

     Reinforced internal structural design effectively avoids misoperation caused by equipment vibration and mechanical impact. It maintains stable working status in complex and dynamic automated production environments.

-- Flexible Differential Pressure Supply Adaptation

     Supports irregular and differential pressure air supply modes with strong circuit compatibility. Flexible system configuration will not affect the valve’s switching accuracy and overall service life.

-- Optional Manual Override for Easy Maintenance

     Configurable non-locking manual override button supports on-site debugging, routine inspection and emergency manual switching, greatly improving installation and maintenance efficiency.
