Description

15 mm WRAS Latching Water Solenoid Valve – RPE 1175BB


A low-power, WRAS approved latching solenoid valve designed for potable water applications where energy efficiency is critical. The RPE 1175BB operates using short pulse signals to open and close, requiring no continuous power to maintain position.

Valve Function and Operation

Function: 2/2 way latching / bi-stable
Operation: Pressure assisted (minimum 0.2 bar pressure differential required)
Port size: 15mm Push Fit Ends (John Guest)
Orifice size: 11.0 mm
Kv flow factor: 25.81 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.

Approvals and certifications

WRAS approved
KTW and DM174 drinking water compliance
ACS health compliance certificate
ENEC European electrical certification
CSV (European Union Aviation Safety Agency)
MOCA FCM (Food Contact Materials)
NSF food certification for public health protection
Optional UL (Underwriter Laboratories) certification

Typical applications

Battery-powered water control systems
Smart water meters and leak detection systems
Drinking water inlet control
Electrical taps and sensor-controlled faucets
OEM potable water equipment requiring ultra-low power consumption

Thank you, nice online store, good clear pictures of the product made it easy to find what I wanted. Order, paid through paypal guest checkout, which, needed some figuring out but that's not your fault, might suggest you try sage pay as a better platform. Valves arrived, boxed and on time, fitted and working perfectly, actually really nice valves to be honest. My rating is on your company and product, not PayPal. I score 90%, no ever gets 100% anyway. Thank you. Bettina.
