Back Pressure Regulators
Mankenberg Industrial Valves
UV3-2 BACK PRESSURE REGULATOR
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 3.2 backpressure regulator is a spring-loaded proportional control valve featuring diaphragm, piston or bellows control. It is designed for small volumes. The valve cone can be fitted with a metallic or soft seal.
- 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:
- Leakage class III (metal sealing cone) = 0.1 % Kvs value
- Leakage class V (soft seal cone) = 1.8 x 10-5 x ?p x D* [l/h] *D=seat diameter
