1" Plastic Zero Differential Solenoid Valve
Technical Details
Product Overview
One of the most common sizes in valves, the PSL-25 line of 1” PA66 Engineered Plastic Normally Closed Electric Solenoid Valve is extremely versatile. These valves boast an EPDM seal, allowing them to withstand a wider range of temperatures than NBR or Viton and offering outstanding resistance to dilute acids, ketones, and alkalis. Normally Closed means that this valve will remain closed until power is applied to the coil; once applied, the valve will open, and once power is removed, the valve will revert to closed.
This valve comes in 5 different common coil voltage configurations: 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC. The coils have an H Class Insulation Rating and an IP65 waterproof level, making them great for indoor or outdoor use, and have a DIN Connector allowing installers to run their own wires into the screw-down terminals inside the connector. The coil is a step-up in power from the smaller valve sizes, allowing this valve to open and close instantaneously (under one second) and function properly up to 100 PSI or with no minimum pressure or gravity feed applications.
The PSL-25 has a 1” female NPT threaded port. It can manage media with a CST of 20 or below and has a flow rate of 12 Cv (Appx 92 GPM @ 60 PSI) and a temperature range of 15°F to 175°F.
Common Applications
- Manufactured from PA66 Engineered Plastic or “Nylon,” this valve is completely lead-free and an excellent choice for potable water and home projects, as well as many other professional uses.
- Along with potable water, this valve can be used with air, gas, fuel, and food-grade applications.
Installation
- This is a uni-directional, 2-way semi-direct normally closed electric solenoid valve, meaning it has two ports but only operates in one direction. This is indicated clearly by an arrow molded into the body.
- A pre-filter is 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.
Wiring Instructions
- Loosen and remove the Phillips-head screw securing the DIN connector to the coil.
- Detach the DIN connector from the coil.
- Open the DIN connector housing by prying at the small slot located in the bottom corner next to the Earth terminal.
- Inside the housing, locate the screw terminals:
- Terminal 1: Connect the hot or positive wire.
- Terminal 2: Connect the neutral or negative wire.
- Earth Terminal (for AC voltages only): Connect the ground or Earth wire.
- Ensure all screw terminals are securely tightened for a reliable connection.
- Reassemble the DIN connector by reversing the steps above.
