The Story
Rmc 15mm 1200kpa Expansion Control Valve is designed to manage excess pressure in unvented water heater systems, ensuring efficient operation and safety.
The Rmc 15mm 1200kpa Expansion Control Valve is a critical component for maintaining optimal pressure levels in pressurised, unvented water heater systems. This valve functions by relieving excess pressure to the drain line, thereby preventing potential hazards associated with overpressure. It is suitable for both horizontal and vertical installations and is resistant to dezincification, making it a durable choice for potable water supply applications. The valve is designed to be installed on the cold or inlet side of the water heater, effectively managing the pressure generated during normal heating cycles. The RMC High Pressure Expansion Control Valve is currently available in a 15mm configuration, ensuring compatibility with various systems.
Features
- Increased heating efficiency by releasing pressure at the inlet
- Suitable for horizontal or vertical installation
- Dezincification resistant for enhanced durability
- Meets Australian Standards for potable water supply
- Limits maximum pressure in unvented water heater systems
