Safety Valve 1/2 MxF 3 Bar with Gauge Port (No Gauge) A314437 CST

Protecting sealed heating or domestic hot water systems from over-pressurisation is vital. This Safety Valve 1/2" MxF 3 Bar With Gauge Port No Gauge A314437 CST, from the Altecnic series 314, performs this critical task. It offers dependable 3 Bar pressure relief and includes a port for easy pressure gauge installation, simplifying system checks for qualified professionals.

Your System's Silent Guardian: Preventing Over-Pressure Damage

The Altecnic series 314 safety relief valves, including this Safety Valve 1/2" MxF 3 Bar With Gauge Port No Gauge A314437 CST, protect domestic hot water cylinders and heating system components. In sealed systems, pressure from thermal expansion or faults can cause damage if not safely released. This 1/2" 3 Bar Safety Valve is set to 3 Bar. If system pressure reaches this, the valve opens, discharging to atmosphere and preventing dangerous pressure levels. Part number A314437 CST ensures reliable protection.

A key feature is its integrated Safety Valve with Gauge Port. Though no gauge is included, this port (typically 1/4" BSP female) allows easy installation of a standard pressure gauge. This helps installers and service engineers monitor system pressure during installation, commissioning, servicing, and fault-finding. With 1/2 inch Male x Female (MxF) BSP threads and robust brass construction, it’s compatible and durable for UK heating and hot water systems.

Key Benefits:

• System Protection: Reliably discharges excess pressure at 3 Bar, preventing damage.
• Pressure Monitoring: Gauge port allows easy fitting of a pressure gauge (not included).
• Durable: High-quality brass for long-lasting performance.
• Standard Connections: 1/2" MxF BSP threads for easy installation.
• Peace of Mind: Ensures safe system operation and regulatory compliance.
