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 8.2 backpressure regulator is a diaphragm, piston or bellows-controlled spring-loaded proportional control valve for high pressures and small
volumes. It can be supplied with three types of connections: sockets, flanges
and welding spigots. Each size of valve may be fitted with three different
seats. The valve cone may be fitted with a soft or metallic 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.
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 III
or V, optional IV.

Standard

» Metallic valve seal

Options

» For toxic or hazardous media: sealed bonnet complete with leakage line
connection (incl. sealed adjusting screw). Must be installed with a leakage line capable of draining leaking medium safely and without pressure
» Various diaphragm and seal materials suitable for your medium
» Special materials such as Duplex, Superduplex, Hastelloy® or titanium,
others on request
» Special connections: ANSI or JIS flanges, NPT, welding spigots; other
connections on request
