MONOSTAB PRESSURE REDUCING
June 19, 2017

Using a direct acting control valve to reduce and stabilise a higher inlet pressure to a lower downstream pressure, regardless of flow . . .

Using a direct acting control valve to reduce and stabilise a higher inlet pressure to a lower downstream pressure, regardless of flow and/or inlet pressure, was developed more than 50 years ago. Design has been optimized in order to provide high robustness, simplicity and very low maintenance.

Today, reliability and accuracy are proven, by using the best quality material and also rolling diaphragm technology, which is much more flexible than a piston mechanism. Effectively, frictions are much less inside than with a piston design. MONOSTAB PRESSURE exists also as a relief valve version.

ADVANTAGE

ACCURACY
Diaphragm guiding and self-lubricated stem coated with a scale inhibitor induces a high capacity to follow the outlet pressure with precision sustainability.

RELIABILITY
Simple and robust construction, stainless steel for all parts subjected to high constraints, high quality elastomers induce very low maintenance need.

EASY DISMANTLING
All internal parts accessible from above, no special tools necessary (mounting lever is included), without having to disconnect the piping.
