VG342 Series 3-Way Pilot Operated Poppet Solenoid Valve | High Flow Vacuum & Pneumatic Control Valve

Brand: SOLH by Richge Technology | High-Flow Low-Power 3-Port Pneumatic Solenoid Valve

1. Product Overview

     The SOLH VG342 series is a high-flow 3-way pilot-operated poppet type solenoid valve, professionally designed for air, vacuum and low-pressure fluid control in standard pneumatic systems. Featuring elastomer sealing, lubrication-free operation, ultra-low power consumption and wide pressure adaptability, it supports flexible switching among normally closed (NC), normally open (NO) and external pilot modes via simple cover replacement. With large flow capacity, fast response and high-frequency cycle performance, it serves as a universal and efficient core control valve for vacuum systems, large-bore pneumatic actuators and multi-circuit manifold pneumatic equipment.

2. Core Product Features

     • Professional Poppet Structure & Reliable Sealing: Adopts 3-port pilot-operated poppet design with high-elasticity elastomer sealing structure, ensuring zero leakage, tight cut-off and stable long-term cyclic operation.

     • Wide Medium & Pressure Adaptability: Suitable for compressed air and vacuum environments. The internal pilot mode supports 0.2~0.9MPa, while the external pilot mode covers full vacuum -101.2kPa to 0.9MPa, adapting to various low-pressure and vacuum working conditions.

     • Lubrication-Free & Low Maintenance: Optimized internal structural design eliminates the need for oil lubrication, reducing daily maintenance costs and avoiding medium pollution, suitable for clean industrial scenarios.

     • Dual Power Consumption Modes & Energy Saving: Standard DC power is only 4W; low-power and long-term energized types achieve 1.8W ultra-low power consumption, effectively reducing equipment operating energy consumption.

     • Superior Large Flow Performance: Maximum effective flow C-value reaches 38 dm³/(s·bar) and Cv value up to 9.8. It supports multiple caliber specifications with effective sectional area up to 210mm², meeting high-flow rapid ventilation demands of large pneumatic components.

     • Flexible Functional Switching: The valve function can be freely converted among NC (normally closed), NO (normally open) and external pilot modes only by replacing the upper cover, realizing multi-purpose of one valve and reducing model inventory costs.

     • Multi-Functional Application: Can be used as a conventional on-off control valve, as well as a selection valve and distribution valve under external pilot configuration, with extremely high scene compatibility.
