Expansion Control Valve

Expansion Control Valve
Variants available: 12mm to 120mm

The Expansion Control Valve is a vital safety component in pressurised, unvented water heater systems, designed to relieve excess pressure during normal thermal expansion. This valve enhances system protection and heating efficiency by safely discharging overpressure to a drain line, preventing damage and maintaining the operational integrity of hot water systems.

Engineered for high-performance and durability, this valve features dezincification-resistant materials, ensuring long-term resistance to corrosion and scaling in potable water applications. It is suitable for both horizontal and vertical installations, offering flexibility and convenience across a wide range of residential, commercial, and industrial water heater setups.

Features and Benefits:

• Variants: Available in 12mm, 20mm, and up to 120mm sizes
• Purpose: Relieves excess pressure generated during the water heating cycle
• Increased Heating Efficiency: Maintains optimal system pressure to reduce energy waste
• Auxiliary Pressure Relief Device: Adds extra protection in the event of drain line obstruction
• Material: Dezincification-resistant brass construction for extended life in potable water systems
• Certified: Meets Australian Standards for potable water supply and safety compliance
• Installation Flexibility: Suitable for both horizontal and vertical installations
• Durability: Designed for continuous operation in harsh water conditions

Applications:

• Domestic and commercial hot water heater systems
• Unvented, pressurised plumbing setups
• Safety and compliance protection in thermal expansion zones

The Expansion Control Valve is a smart, reliable choice for ensuring safety, pressure regulation, and long-term performance in any water heating system. Essential for meeting Australian plumbing codes, it's a must-have for professional installations.
