Description
1/4 inch plastic latching / bi-stable water solenoid valve WRAS approved 1186BB RPE Mini R
A compact 2/2 way latching / bi-stable plastic water solenoid valve with quick-connect, designed for low-power operation in drinking water systems, taps, and washing machines.
Valve function & operation
- Function: 2/2 way latching / bi-stable (20 millisecond pulse)
- Operation: Pressure assisted (requires Min 0.2 Bar pressure difference)
- Port: 1/4 inch quick connect / speed push fit
- Pressure range: 0.2 to 10 Bar
- Orifice size: 11.0mm
- Kv flow factor: 17.57 L/min (based on water with 1 bar pressure difference)
- Control principle: Short power pulse to open, reverse polarity pulse to close
- Maximum pulse duration: 20 milliseconds
Construction & materials
- Body: Nylon white good grade 30% Glass Filled
- Seals: NBR standard, option EPDM
- Coil type: Latching / bi-stable
- Power consumption: 2.25 W
- Ingress protection: IP00
- Electrical connection: Faston tags 6.3x0.8mm (option flying lead wires)
Voltage requirements
- Nominal voltage: 6 V DC
- Current draw: 375 mA
- Pulse duration: 15 to 20 milliseconds
- Voltage tolerance: Accepts 9 V DC and 12 V DC with reduced pulse duration
Operating principle
A short low-power pulse (approximately 15 ms) energises the internal magnet to open the valve and hold it open without continuous power.
A short reverse-polarity pulse (approximately 15 ms) cancels the magnetic field, closing the valve.
This process is repeated for each open and close cycle, significantly reducing overall power consumption.
