2WM Series Brass 2/2-Way Solenoid Valve
- Pilot Operated, Normally Closed
- Port Size: 1/4"–2"
- Fluid Temperature: -5°C to 80°C (120℃ optional)
- Operating Pressure: 0.5–1.6MPa
- Media: air, water, oil, gas
2WM series is an innovative dual-control solenoid valve integrating manual and electromagnetic actuation, developed specifically for fire-emergency scenarios, with manual-priority control. Constructed with a fire-resistant brass body and equipped with a distinctive red manual knob, this valve allows for fast one-hand emergency operation. The valve provides excellent sealing performance and high-temperature endurance, ensuring reliable activation even under extreme fire-site conditions. It provides both automated efficiency and manual override as a dual safeguard for modern fire-protection systems.
- Manual-priority operation with a red quick-action knob for one-hand emergency activation
- Optional high-temperature diaphragm ensures sealing integrity under fire conditions and full brass body corrosion resistance
- IP65-rated protection against dust and low-pressure water spray for complex installations
- Manual-release mechanism at the bottom for mechanical operation during power loss
- Supports horizontal or vertical installation, with a compact structure ideal for space-limited environments
- Combines automatic solenoid actuation with manual intervention to ensure standby safety and uninterrupted operation
This solenoid valve is widely applied in fire-protection systems across commercial buildings, industrial facilities, and public infrastructure, where high reliability and temperature endurance are critical, such as:
- Fire hydrant systems
- Automatic fire sprinkler systems
- Foam fire extinguishers
- Gas-based fire-extinguishing systems
