Product Overview
The PSL-25K line of 1” PA66 Engineered Plastic Normally Open Electric Solenoid Valve is extremely versatile. Manufactured from PA66 Engineered Plastic or “Nylon,” this valve is completely lead-free. The wetted components in this valve are the PA66 body, EPDM seal, and Stainless Steel components, allowing it to withstand a wider range of temperatures than NBR or Viton, and all materials offer outstanding resistance to dilute acids, ketones, and alkalis.
This Normally Open Solenoid Valve is available in 5 different common coil voltage options: 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC. The term normally open refers to the valve's position without power; this valve will be open without power and close when power is applied to the coil. The coils have a Coil Class H (356°F) and an IP65 waterproof level, making it 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 510 series coil is a step-up in strength from the smaller valve sizes, allowing this valve to snap closed instantaneously (under one second) while maintaining a pressure rating of 0 to 90 PSI. This valve has a 25mm orifice and zero-pressure differential requirements, with a flow rating of 12 Cv; this is an ideal choice for gravity feed applications.
Common Applications
- This valve is commonly used for potable water and food-grade applications.
- The rigidity, stability, and chemical resistance of its components make it a great option for many fluids and inert gases at a wide range of temperatures and pressures.
Installation
- Like most solenoid valves, the PSL-25K is uni-directional, meaning this valve will only function properly with media flowing from inlet to outlet.
- The direction of flow is indicated by an arrow on the bottom of the valve body. This valve is not intended to be used as a check valve or backflow prevention. If the application has backflow present, an inline check valve is recommended to protect the valve and allow it to open and close properly.
- Both ports are 1” Female NPT threaded, making installation easy.
- 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.
