Description
The Sanlixin ZS1DF02N4G25 stainless steel solenoid valve is a robust 2/2-way, direct-acting, normally closed valve designed for automatic control of water and other compatible fluids.
Manufactured with an SS304 stainless steel body, NBR seals and a 25mm orifice, this 1″ valve provides reliable automatic flow control for domestic, commercial and industrial water-treatment applications.
The valve remains closed when the solenoid coil is de-energised and opens when electrical power is supplied. Its direct-acting design allows the valve to operate from zero differential pressure, making it suitable for systems where water pressure may vary.
With a Cv of 12, maximum operating pressure of 10 bar and maximum fluid temperature of 80°C, the Sanlixin ZS1DF02N4G25 is suitable for reverse osmosis, water filtration, water purification, tank filling, irrigation, automatic plumbing and industrial fluid-control applications.

How it works:
The valve is normally closed, meaning that it automatically remains shut when there is no electrical power supplied to the solenoid coil.
When the valve is off:
The internal valve remains closed and stops the flow of fluid.
When the valve is energised:
The electromagnetic solenoid activates the internal mechanism, opening the valve and allowing fluid to flow.
Because this is a direct-acting valve, it can operate from zero differential pressure, making it useful in applications where there may not always be pressure available to assist valve operation.
