## Description

Full description not available

## Features

- [MATERIAL]: The product is mainly made of cast copper with copper coil, which improves the strength and applicability of the valve
- [SIZE]: 102mm*62mm (4.016" * 2.44"), thread diameter: 20mm (0.787"), interface pipe diameter: 1 / 2" NPT thread, flow diameter: 16mm (0.63")
- [N/C]: The solenoid valve is normally closed, which means it is closed when the power is not supplied, which effectively ensures the safety of use.
- [WIDE APPLICATION]: Applicable temperature: - 5 ℃ ~ 80 ℃,Working pressure: water, air: 0 ~ 7kgf/cm2. Working environment: water, air, compressed air and some stable gases.
- [MATTERS NEEDING ATTENTION]: Amps power required by adaptor: at least 1.2A. As the product is normally closed solenoid valve, the working time shall not be too long, and the working time is recommended to be less than half an hour. If more than half an hour will begin to appear heating state, after the solenoid valve heating, try to let it rest for half an hour before working.

    Welder Upgrade
  

*by B***W on Reviewed in the United States on March 10, 2024*

Bought this to run gas on my MIG welder.  With a few hose fittings, this woks great on my welder.  The factory kit was over $200; I spent maybe $70 for the same stuff.

    It looks like most of the ones with similar specs are in fact the same units
  

*by A***R on Reviewed in the United States on November 19, 2020*

This is a plain diaphragm-type (not a spool) solenoid valve. I have not used this one but I have used several similar ones in the past. They do work. The one I bought this time is my 1st one with 1/4" trade size ports. I have used them mostly for water but this one will be for an air line. The coils are removable so I assume the actual valve part (for a given port size) is the same and they just swap coils for different voltages. The wire leads are not too long so you'll most likely need to extend them somehow. BTW the 5-7 KGF/CM2 (kilogram_force per square centimeter) equates to 71 to 99 psi, but the label on the valve that I received says "MIN 0kg/cm2 MAX 10kg/cm2" which would be 0 to 142 psi). The other comments about following the flow direction arrow are correct so put your higher and probably more continuous pressure on the 'tail' of the arrow (in the brass casting) and the 'controlled' side of your plumbing on the pointy end of the arrow; i.e. the flow goes the same as the arrow direction. If you look into the unplumbed ports you can see that the 'tail' side is 'above' the diaphram which is the controlling part of the valve and thus should have higher pressure in order to close off (this is a normally closed valve).
