Adjustable pressure reducing valve 1 to 5.5 bar double female 15x21

Adjustable Pressure Reducing Valve 1 to 5.5 bar Double Female

The Desbordes 7 BIS pressure reducing valve is designed to maintain a constant and adjustable downstream pressure between 1 and 5.5 bar. It operates both in flow and at zero flow, ensuring high flow with low pressure loss.

Made of bronze, it is resistant to scale and impurities, guaranteeing maintenance-free operation. This model is delivered pre-set at 3 bar and complies with EN 1567 standard.

It is intended for water networks and can also be used as a regulator or pressure reducer for certain neutral gases and compressed air, under specific conditions.
