Südmo Constant Pressure Valve

Maintaining a reliable, repeatable back pressure on process lines with varying flow rates and viscosities is a challenge in today’s processing facilities. Traditional back pressure valves are costly and hard to maintain. They use laminated diaphragms,which are prone to cyclic fatigue, pressure shocks and chemical attack fromaggressive media and cleaning chemicals.These diaphragms are expensive to replace,both in materials costs and plant downtime.

What sets our Constant Pressure Valve apart from the competition is that it is available in more sizes – from 1 to 4 inches – and has a stainless steel regulating cone instead of a diaphragm. The simpledesign is a variation on our proven single seat valve range. It can be retrofitted into any existing system, regardless of manufacturer. With no automation
required, the self-regulating air supply unit is set at installation and the need for
adjustment is eliminated.
