Reliance High Pressure Expansion Control Valve 15mm (1/2") 700kPa - H504

Model: H504

Reliance High Pressure Expansion Control Valve 15mm (1/2") 700kPa - H504
MC H50/H75 Series are for use on mains pressure water heaters. They are available in pressure settings from 550 kPa to 1400 kPa and in 15 mm and 20 mm nominal diameters  

High Pressure Expansion Control Valves limit the maximum pressure in a pressurised, unvented water heater system by relieving excess pressure to the drain line. The valve is a functional control for this type. of application. High Pressure Expansion Control Valves should only be installed on the cold or inlet installation on a water heater as the valve is primarily intended to cope with the excess pressure generated during a normal heating cycle. RMC High Pressure Expansion Control Valves are available in 15 mm and 20 mm configurations.

• Increased heating efficiency
  » Releasing pressure at the inlet saves energy by not purging heated water
• Auxiliary pressure relief device
  » Use of an expansion control valve for pressure relief leaves the pressure and temperature relief valve to perform only a safety valve function.
• Female BSP thread on outlet thread
  » Prevents incorrect installation to the system
• Sealed spring cavity
  » Prevents spring from seizing in the event of calcification
• Dezincification resistant
  » Meets Australian Standard for potable water supply
• Suitable for horizontal or vertical installation
  » Valve designed to work effectively in either orientation

The RMC High Pressure Expansion Control Valve range of relief valves are suitable for use on water heater inlets or for any application where expansion safeguards are necessary. RMC recommends installing an High Pressure Expansion Control Valve as part of a complete inlet control system for water heater applications. Please ensure that the set pressure of the High Pressure Expansion Control Valve is suitable for use with the water heater it will be installed with. For more information refer to the Specification Tab.
