RMC HPNR503 High-Pressure Expansion Non-Return Valve 15mm · 1400kPa

Description

RMC HPNR503 is a 15 mm high pressure expansion non-return valve for coil type heat exchange water heaters. It combines non-return and pressure relief functions in one valve.

The non-return function helps prevent hot water backflow into the mains supply, while the relief valve protects the coil from over-pressure. It is intended for installation on the cold/inlet supply of a compatible water heater.

Features

• Combination non-return and pressure relief valve for heat exchange water heaters.
• Directs expanded water back to the storage tank rather than dumping it to waste.
• Suitable for horizontal or vertical installation.
• Dezincification-resistant brass construction for potable water applications.
• Sealed spring cavity helps prevent the spring seizing due to calcification.
• 1 year warranty.
