What is a Water Solenoid Valve?
A water solenoid valve is an electrically operated valve used to automatically control the flow of water. When energised, the valve opens or closes via an electromagnetic coil, allowing precise on/off control without manual intervention.
These valves are widely used in:
→ Irrigation systems
→ Water treatment and filtration
→ Commercial appliances
→ Industrial process control
Key Features of Our Water Solenoid Valves
→ Fast opening and closing response

Common Applications for Water Solenoid Valves
Domestic & Commercial Water Systems
Used for automatic shut-off, leak protection, and system control.
Irrigation & Agriculture
Ideal for timed watering systems, sprinkler control, and water distribution.
Industrial Water Control
Widely used in cooling systems, process water lines, and wash down systems.
Water Treatment & Filtration
Control flow in filtration units, RO systems, and dosing applications.
WRAS Approved Water Solenoid Valves
WRAS (Water Regulations Advisory Scheme) approval ensures valves are safe for use with potable (drinking) water in the UK.
Our WRAS approved valves:
→ Meet UK water supply regulations
→ Prevent contamination of drinking water
→ Are ideal for commercial and residential installations

Ideal for aggressive environments, hygiene-sensitive applications, and higher durability.
Plastic (WRAS) Water Solenoid Valves
Lightweight, corrosion-resistant, and perfect for potable water systems.
Sizes, Voltages & Configurations
Available Sizes
→ 1/8" to 3" BSP
→ High flow and standard flow options
Voltage Options
→ 24V DC – control panels and low-voltage systems
→ 24V / 110V / 230V AC – industrial and mains applications

How to Choose the Right Water Solenoid Valve
Key Selection Factors
→ Pressure range (min/max operating pressure)
→ Flow rate (Kv value)
→ Media temperature
→ Material compatibility
→ Electrical supply (voltage & duty cycle)
→ WRAS approval (if potable water)
Direct Acting vs Pilot Operated Valves
Direct Acting Valves
Operate without pressure differential — ideal for low pressure or zero pressure systems.
Pilot Operated Valves
Require minimum pressure but offer higher flow rates and efficiency.
Maintenance & Reliability
Our valves are designed for long service life with minimal maintenance.
→ High-quality coils for continuous duty
→ Durable seals for water applications
→ Easy installation and replacement
Frequently Asked Questions
Can water solenoid valves be used for drinking water?
Yes — but only WRAS-approved models should be used for potable water systems in the UK.
What is the difference between NC and NO valves?
NC (normally closed) valves stay closed without power; NO (normally open) stay open without power.
Do solenoid valves need pressure to operate?
Direct acting valves do not require pressure. Pilot-operated valves require a minimum pressure differential.
How long do water solenoid valves last?
Typical lifespan depends on application but can exceed millions of cycles with proper selection and installation.
