2W400-40

2W400-40 1-1/2'' NC Diaphragm Water Brass Solenoid Valve

The 2W400-40 solenoid valve is brass valves two-way, semi-direct lift valve that operates in a normally closed position.This means that there are two ports in which the medium flows and the valve will open to allow the medium to pass when the coil is energized. 2 / 2 Way G1-1/2 Inch Normal Close Type Operated Brass Solenoid Valve 2W400-40.High quality electric solenoid valve, for water, air or oil. It's applicable in many fields. 

Direct Acting

When the solenoid is energized, the core directly opens the orifice of a Normally Closed valve. The valve will operate at pressures from 0 psi to its rated maximum. The force needed to open the valve is proportional to the orifice size and fluid pressure. As orifice size increases, so does the required force. To open larger orifices without increasing solenoid size, internal pilots are used.

Normally Closed (NC)
Fluid is shut off when the coil is de-energized, flows through the valve when the coil is energized.

Application:

1. Please refer to the user manual of the product before installation to see whether it meets your requirements.
2. The pipeline should be cleaned before use, and the filter should be installed if the medium is not clean to prevent impurities from interfering with the normal work of the solenoid valve.
3. The solenoid valve generally works in one direction and cannot be installed in reverse. The arrow on the valve is the movement direction of pipeline fluid and must be consistent.
4. Solenoid valve installation of the general body horizontal, vertical upward coil, some products can be arbitrarily installed, but when conditions allow the best vertical, in order to increase the service life.
5. After the lead wire of the electromagnetic coil (connector) is connected, it shall confirm whether it is firm or not. The contact point of the connecting electrical components shall not shake.
6. To continuous production work of the solenoid valve, the best use of bypass, easy maintenance, do not affect production.
