Pressure Reducing Valves

Universal Pressure Reducers for all applications


Pressure Reducing Valves are designed to 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.


These self-acting pressure regulators are used to protect all the devices, valves and installations situated downstream from any excessive pressure build-up. Simultaneously the consumption is reduced and the flow velocity and noise are minimised.


A spring keeps the valve open and the outlet pressure moves through the control element (diaphragm, piston or bellows) onto the cone, and in the event of rising outlet pressure, proportionally closes the valve. The outlet pressure to be controlled can be adjusted by a pre-tensioned/relieved spring via an external adjusting screw.
