Know How Pressure Reducing Valves
Pressure reducing valves reduce a high and frequently fluctuating pressure to an adjustable constant pressure downstream of
the valve. A spring keeps the valve open and this closes as the outlet pressure rises.

Setting the pressure
Pressure reducing valves are normally supplied by us with a relaxed
spring. This means that a valve is set at the factory to the minimum
outlet pressure. The required pressure should be set under operating
conditions.
Maintenance
Pressure reducers must be cleaned and serviced regularly.
Valves free of oil and grease or silicone
Please pay attention to order an fit only spares free of oil and grease
resp. free of silicone.
