Brass Pressure Reducing Safety Valve G1/2" DN15 0.75MPa
Brass Pressure Reducing Safety Valve — G1/2" DN15 0.75MPa
Keep your electric water heater running safely and efficiently with this heavy-duty brass pressure reducing valve. Designed for standard G1/2" (DN15) cold water inlets, it automatically manages tank pressure to prevent backflow and protect your water heater from damage — extending its service life and helping avoid costly repairs.
Key Features
- Prevents water backflow — built-in check structure stops reverse water flow into the supply line
- Automatic pressure regulation — set relief pressure of 0.75MPa keeps your water heater tank operating within safe limits
- Universal compatibility — fits all major brands of electric water heaters up to 50 litres capacity
- Durable brass construction — corrosion-resistant solid brass body for long-lasting, reliable performance
- Easy installation — standard threaded connection mounts directly onto the cold water inlet of your water heater
- Electricity-free operation — purely mechanical design; no wiring or power supply required
- Protects tank integrity — helps prevent cracking or deformation of the water heater tank caused by excess pressure buildup

Frequently Asked Questions
Q: What size water heater is this brass pressure reducing valve compatible with?
A: This G1/2" DN15 brass safety valve is compatible with all major brands of electric water heaters up to 50 litres capacity. It installs onto the standard cold water inlet fitting found on most residential water heaters in this range.
Q: Why do I need a pressure reducing valve on my electric water heater?
A: As water heats up inside the tank, it expands and creates pressure buildup. Without a pressure reducing valve, this excess pressure can cause the tank to crack or degrade over time. This valve automatically manages tank pressure at 0.75MPa and prevents backflow, protecting your appliance and extending its lifespan.
Q: Does this valve require any electrical connection?
A: No, this is a fully mechanical, electricity-free valve. It operates purely on water pressure dynamics — no wiring, batteries, or power source of any kind is needed.
Q: How do I install this pressure reducing valve?
A: Simply thread the G1/2" (DN15) valve onto the cold water inlet connection of your electric water heater. Ensure the water supply is shut off before installation, then tighten securely and restore the water supply. No specialist tools are typically required for standard installations.
