Fluid Regulators stabilise and control fluid pressure

Transfer, extrusion and spray applications often require uniform fluid pressure with minimal fluctuations. Examples of this are a steady flow in a transfer application, a consistent bead in an extrusion process or a constant pressure for high quality finishing in a spray application. Control can be achieved by using a fluid regulator, a self-adjusting valve that senses fluid pressure at the outlet of the regulator and holds it constant.

Back Pressure Fluid Regulators

A back pressure fluid regulator senses the pressure at the inlet to the regulator and holds it constant, eliminating undesirable effects on other equipment in the system, e.g. pressure build-up at the head of the application that forces fluid back through the pump or fluid pressure that acts on the outlet of the pump causing the pump to respond slowly on demand.

Pressure Relief Valves

A relief valve is designed primarily for safety reasons and for protecting other equipment in the system. The valve relieves pressure by expelling fluid from the system when the pressure exceeds a predetermined level.

Pulsation dampers

These iron out flow and pressure fluctuations caused by pumps as they cycle. A good example of using a pulsation damper is with a Double Diaphragm pump: there is a marked pressure drop when the pump reaches the end of its lateral stroke and the diaphragms reverse direction; then there is a surge when it begins a new stroke. This pulsation can be a problem with some, but not all, applications. We have a range of pulsation dampers with different wetted parts to tackle many fluids. Model numbers 209030,203831,205425.
