Description

The Sanlixin ZS1DF02N4J40 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 40mm orifice, this 1½″ solenoid valve is designed for commercial and industrial applications requiring reliable automatic flow control.

The valve remains closed when the solenoid coil is de-energised and opens when the correct electrical power is supplied. Its direct-acting design allows operation without requiring a minimum differential pressure, making it suitable for systems where pressure conditions can vary.

With a Cv of 29, a 0–10 bar pressure range, maximum fluid temperature of 80°C, and a robust 2.9kg construction, the Sanlixin ZS1DF02N4J40 is suitable for industrial water treatment, reverse osmosis, filtration, water purification, tank filling, industrial plumbing and automated fluid-flow control.

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.
