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 4.5 ASME is a diaphragm-operated, springloaded and balanced proportional valve for high flow rates. The valve body is
made of cast steel. Diaphragm housing, bonnet and internal parts are made
of stainless steel. The valve cone is fitted with a soft seal.
The inlet pressure to be controlled is balanced across the valve seat by the
force of the valve spring (set pressure). If the inlet pressure rises above the
set pressure, the valve opens. With decreasing inlet pressure the valve control orifice reduces. When the pipeline is depressurised, the valve is closed.
Rotating the adjusting screw clockwise increases the inlet pressure.
The valve requires a sense line (to be installed on-site).
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 V.
