Description

3/4 inch WRAS plastic latching / bi-stable water solenoid valve – RPE R Mini 6115BB


The RPE R Mini 6115BB is a WRAS approved, latching / bi-stable plastic water solenoid valve with integrated inlet filter, designed for energy-efficient and reliable potable water control. Its short pulse operation drastically reduces power consumption while maintaining high performance, making it ideal for appliances, water inlets, and automated drinking water systems.

Valve function and operation

Function: 2/2 way latching / bi-stable
Operation: Pressure assisted (minimum 0.2 bar pressure differential required)
Pressure range: 0.2 to 10 Bar
Integrated inlet filter: Yes
Port size: 3/4 BSP male thread
Orifice diameter: 11.0 mm
Kv flow factor: 27.07 L/min (Based on water with 1 bar pressure drop)
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.
