Product Overview

Our PSL-15K line of Engineered Nylon Plastic electric solenoid valves are 1/2” semi-direct lift valves operating from a normally open position. Normally open valves stop the flow of media between the valves ports when power is applied, when power is removed the valve will spring back open and allow media to pass through. This valve is unidirectional two-way valve which means it has two ports, one in which the media flows into the valve and the second where the media exits the valve. This is conveniently labeled with an arrow to indicate the direction of flow.

This valve has a 1/2” female NPT threaded port. It can handle media with a CST of 20 or below and has a flow rate of 4.8Cv (Appx 36 GPM @ 60 PSI). The EPDM allows this valve to handle a wider temperature range than NBR or Viton seals, boasting a temperature range of 15°F to 250°F and a pressure range of 0-90PSI.

The PSL-15K comes in 6 voltages, 12V DC, 24V DC, 24V AC, 110V AC and 220V AC Coils with DIN 43650A connection type and a H Class – IP 65 – NEMA 4 enclosure rating making it weather tight and good for either indoor or outdoor use providing a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water.  These coils allow the valve to open and close almost instantly, with a response time of under 1 second making the valve reliable and accurate.

The valve body is molded from PA 66, Engineered Nylon Plastic, making it completely lead free and an ideal choice for controlling potable water or food grade applications.

A pre-filter is always recommended to keep the diaphragm free from debris and the valve functioning properly.

*Consult a chemical compatibility expert for correct seal and valve body material choice.
