VT325 Series 3 Port Solenoid Valve – Direct Acting Poppet Type

Brand: SOLH by Richge Technology | SOLH Standard

1. Product Positioning

     The SOLH VT325 Series is a direct‑acting poppet type 3-port solenoid valve featuring full elastic sealing. Designed for compressed air and inert gas circuits, it performs air circuit on‑off, directional switching and exhaust control. Supporting zero‑pressure startup and compatible with both positive pressure and full vacuum conditions, the VT325 serves as a high‑frequency, stable and reliable pneumatic switching component for general industrial automation equipment.

2. Core Key Features

--Direct Poppet Structure & Zero‑Pressure Startup

     No minimum operating pressure required. It operates stably across a full positive pressure range of 0–1.0 MPa. The vacuum version supports working pressure down to -101.2 kPa, fully adaptable to low‑pressure, vacuum and high‑pressure working scenarios.

--6‑in‑1 Multi‑Function Design for Universal Piping

     By changing port connection modes, a single valve realizes 6 functional modes, including NC (Normally Closed), NO (Normally Open), flow division and flow selection. It covers diverse pneumatic logic requirements with excellent versatility and flexible configuration.

--Ultra-High Flow Capacity & Fast Response

     Equipped with optimized internal flow passages, the valve delivers a large flow coefficient of C=6.1 dm³/(s·bar). It achieves a fast response time ≤30 ms and supports a maximum switching frequency of 5 Hz, perfectly suited for high‑speed pneumatic switching and high‑flow air supply control.

--Elastic Sealing & Lubrication‑Free Operation

     Adopts high‑quality elastic sealing materials for excellent airtightness, anti‑aging performance and long service life. Completely lubrication‑free operation ensures clean gas circuits, environmental friendliness and significantly reduced daily maintenance costs.

--Compact Structure & Flexible Installation

     Mini and compact body saves installation space. It supports both direct wire outlet and socket wiring methods. Equipped with a standard non‑locking manual override button for convenient on‑site debugging, inspection and emergency manual switching.

--Manifold Mountable & Strong Compatibility

     Supports dense manifold assembly and stacking installation. Dimensionally compatible with standard industrial valve islands, making it ideal for modular centralized pneumatic control systems and automated integrated equipment.
