3/4" Brass Solenoid Valve – Normally Open (DN20)
3/4" (DN20) normally open brass solenoid valve designed for low-pressure water and compatible gas systems. Available in multiple AC and DC voltage options, this diaphragm-type valve provides reliable electrically controlled flow for industrial, commercial, and utility applications.
This 3/4" brass solenoid valve (DN20) is engineered for electrically actuated flow control in water and compatible gas systems. In its default state (de-energised), the valve remains open. When power is applied, the valve closes, making it suitable for applications requiring power-to-close functionality.
The diaphragm-operated design ensures dependable sealing performance and consistent operation in low-pressure environments. The brass body offers durability and corrosion resistance, suitable for plant rooms, irrigation systems, gas control circuits, and automation installations.
Available in common AC and DC voltage configurations, the valve integrates easily with PLC outputs, timers, thermostats, relays, and building management systems.
Typical Applications:
-
Irrigation and water distribution systems
-
Compressed air and compatible gas systems
-
HVAC water circuits
-
Utility shut-off systems
-
Industrial automation panels
-
Pump and tank control systems
