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.
