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 UV 5.1 backpressure regulator is a spring-loaded diaphragm-controlled
and balanced proportional control valve for universal application. This bypass valve is manufactured from deep-drawn stainless steel featuring excellent corrosion resistance. The valve cone is fitted with a soft seal.
The spring module comprising bonnet, spring, adjusting screw, diaphragm
and internal components, is connected to the valve body only by means of a
clamp ring and two bolts. Changing the diaphragm or the complete spring
assembly for a different control pressure range is extremely simple and does
not call for special tools. The same applies to servicing and maintenance.
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.
