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.
