Resideo Braukmann SV300 Pilot Operated Safety Valve

The Resideo Braukmann SV300 Pilot Operated Safety Valve is expertly engineered to manage the medium flowing through it via an integrated pilot valve. This valve is ideally suited for installation in supply pipework branches, providing crucial protection for downstream components that could be compromised by excessive pressure, often arising from pump activities. When the inlet pressure reaches the pre-set opening pressure, the valve promptly transitions to the maximum flow position. Conversely, if the pressure decreases to the designated level, the valve gradually closes to mitigate pressure shock loads.

Ensure the safety and efficacy of your system with the Resideo Braukmann SV300 Pilot Operated Safety Valve, the ideal choice for managing pressure and safeguarding essential components within your water supply infrastructure.

The Altecnic / Caleffi 253 Solar Safety Valve - 253046 is designed to regulate pressure within the primary circuits of solar heating systems. This valve is specifically chosen based on the required set pressure. As pressure increases within the system, the valve activates when the discharge pressure is reached, releasing excess pressure to the atmosphere. This vital function helps prevent potential damage to solar collectors and other system components caused by excessive pressure levels.
