We set the default pressure for overflow valves to the lowest level possible. The purpose of this is to relieve the spring and valve seat/seal. For example UV01020005 corner overflow valve 1” inch IG type UV01 set range 2.0 - 12 bar (always delivered with a default pressure of approx. 2 bar) 

The UV13 series is excepted!
This is generally delivered in the medium range of the setpoint value.

We are also happy to set the overflow valve to your desired pressure at the factory. Please simply indicate this in your order.

The membrane-operated pressure reducing valve is frequently used in applications with low to normal back pressure. Due to the membrane, it also delivers more sensitive regulation.

The piston-operated pressure reducing valve is frequently used with high back pressures and aggressive media. It has an extremely robust design, giving it a high level of safety in case of pressure surges.
