Product Overview
The PSL-20 is a 2-way, 3/4” Engineered Nylon Plastic (PA66) electric solenoid valve. The engineered nylon plastic, PA66, has high mechanical strength, rigidity, and good stability under heat and chemical resistance. This valve is an affordable and dependable choice to control water, air, gas, and fuel. It is a normally closed, 2-way valve, meaning it will remain in its closed position until power is applied; when power is supplied, the valve will move to the open position.
The valve is molded from PA 66, Engineered Nylon Plastic, making it completely lead-free and an ideal choice for potable water or food-grade applications. It has a 20 mm orifice, and the flow rate can be calculated using the valve's Cv of 7.6 (Appx 58 GPM @ 60 PSI). It is unidirectional and will not operate properly in applications with backflow.
The PSL-20 comes in multiple voltage configurations. Choose from 12V DC, 24V DC, 24V AC, and 110V AC Coils with DIN 43650A connection type and IP65 enclosure rating. 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.
This valve features an EPDM (ethylene propylene diene monomer rubber) seal, which offers outstanding tear and abrasion resistance as well as good resistance to dilute acids, ketones, and alkalis. This seal allows this valve to handle a wider temperature range than NBR or Viton seals.
Installation
- This valve can be mounted in any position.
- To prevent improper installation, there is an arrow on the body to clearly indicate the direction of flow.
- A pre-filter is always recommended to keep the diaphragm free from debris and the valve functioning properly.
- Connection: No Polarity; positive (+) and negative (–) can be interchanged.
*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.
