Supply pressure regulators: supplying pneumatic measuring and control equipment with a constant supply pressure

Supply pressure regulators by SAMSON
|   Know how

Supply pressure regulators are used to provide pneumatic control equipment with a constant supply pressure. They control the pressure of a compressed air network to the adjusted pressure. The Type 4708 Supply Pressure Regulator can be used in a wide variety of applications. The regulator is quick and easy to adjust at the adjustment screw. Low-temperature versions for use down to –50 °C are available for some device versions.

Our supply pressure regulators can be equipped with a filter receptacle and a pressure gauge on the outlet side. The pressure gauges are available entirely made of stainless steel (therefore completely free of any copper alloy) or with a stainless steel housing and brass measuring element. The body is available either in aluminum or stainless steel.
