7V Series Compact Pilot Operated 5/2 & 5/3 Solenoid Valve

Brand: SOLH by Richge Technology

Product Positioning

     SOLH 7V series is a compact pilot-operated directional solenoid valve covering 5/2-way and 5/3-way functions, specially designed for general standard pneumatic circuits. Adopting internal centralized exhaust structure with optimized flow channel, it delivers remarkable large flow capacity, fast switching response and low power consumption. It can be used standalone or assembled into manifold valve banks for centralized control of multiple cylinders.

Core Structure & Functional Classification

  1. Port & Position Function Definition：

   1.1  5/2 Way Solenoid Valve：1 inlet P, 2 working ports A/B, 2 exhaust ports R/S

     -- 10 suffix: Single coil single solenoid spring return

     -- 20 suffix: Double coil double solenoid latching type

   1.2 5/3 Way Double Coil Solenoid Valve (3 center core functions)

     -- 30C Center Closed: All ports fully sealed at mid position to lock cylinder pressure for clamping holding

     -- 30E Center Exhaust: A & B connected to exhaust R/S to release residual pressure safely

     -- 30P Center Pressure Supply: P connected to both A and B, both sides of cylinder maintain air pressure

  2. Drive & Structural Feature

     -- Drive Type: Pilot operated design, low startup pressure, ultra-fast response and large flow output

     -- Internal centralized exhaust: Pilot air exhausted uniformly via main exhaust ports R/S, clean and tidy piping without scattered pilot exhaust

Core Product Advantages

  1. Enhanced high flow performance

     -- Optimized internal streamline runner design, flow capacity increased by around 30% compared with traditional 4V series solenoid valves, realizing faster cylinder extension & retraction speed.

  2. Flexible multi-direction installation & dual port options

     -- Supports horizontal and vertical mounting; two connection modes: standard thread port or quick push-in fitting for fast tubing assembly.

  3. Manifold integrated modular design

     -- Compatible with multi-station manifold valve base, multiple valves stacked together to save cabinet installation space and simplify main air piping layout.

  4. Ultra-low power coil

     -- Low wattage coil design reduces heat generation, suitable for long-term continuous energized working conditions with lower energy consumption.

  5. Ultra-long service lifespan

     -- Precision internal spool and sealing structure, stable performance up to millions of switching cycles with minimal maintenance.
