Description
Self-acting back pressure regulators are simple control valves offering accurate control while being easy to install and maintain. They control the pressure upstream of the valve without requiring pneumatic or electrical control
elements.
The back pressure regulator UV 1.5 is a pilot-operated control valve with
proportional control mode consisting of main valve and pilot valve. It is completely made of stainless steel with excellent corrosion resistance. Its intermediate flange design with limited size makes the valve extremely lightweight and compact. The valve cone has a metallic seal.
The sturdy valve design and the metallic valve seal do not require any particular filtration of the operating fluid. Thanks to its medium-wetted movable
components, the valve is largely maintenance-free. In addition, it can be installed in any desired mounting position.
Special notes:
The seal on the outlet side must not cover the outflow bore of the pilot valve
(observe measurement!)
These valves are no shut-off elements ensuring a tight closing of the valve.
In accordance with DIN EN 60534-4 and/or ANSI FCI 70-2 they may feature
a leakage rate in closed position in compliance with the leakage classes II.

Typical applications
Maintaining the required lub oil pressure for the use of main and auxiliary oil
pumps, for ex. compressors, gears, slide bearings, drive shafts etc., Pressure control of fuels / fuel oils in power plants.
Control of minimum quantities for centrifugal pumps with oil / oily fluids. Lub
oil systems, for ex. for steam and gas turbines, large diesel engines for ship
propulsion and cogeneration units (CHP).
Operating instructions, know how and safety instructions must be observed.
The pressure has always been indicated as overpressure. We reserve the
