2W water (hot water) gas normally closed solenoid valve
The 2W Normally Closed Solenoid Valve is designed for controlling the flow of water, hot water, and gas in a variety of industrial, commercial, and residential applications. It is a direct-acting, two-way, normally closed (NC) solenoid valve, which remains closed when the coil is de-energized and opens when power is applied.
2W Normally Closed Solenoid Valve
This type of solenoid valve is known for its fast response, compact design, reliable sealing, and long service life. It is suitable for automation systems, HVAC systems, gas burners, water heaters, and industrial fluid control systems.
