Description

The Sanlixin stainless steel solenoid valve ½″ 16mm is a high-quality, direct-acting 2/2-way normally closed valve designed for automatic control of water and other compatible fluids.

Featuring a ½″ BSP threaded connection, 16mm orifice, SS304 stainless steel body and NBR seals, this solenoid valve offers reliable automatic flow control for commercial and industrial applications.

The valve remains closed when the coil is de-energised and opens when electrical power is supplied. Its direct-acting design allows operation from zero differential pressure, making it suitable for a wide range of automatic water-control applications.

With a Cv value of 4.8, maximum operating pressure of up to 10 bar, depending on the medium and electrical configuration, and a maximum fluid temperature of 80°C, the ZS1DF02N4D16 is suitable for water treatment, reverse osmosis, filtration, tank filling, irrigation and industrial fluid-control systems.

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.
