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 1.3 is a seat-controlled, spring-loaded backpressure regulator for the protection of pump systems or other pressurised vessels or pipes with high throughputs. The opening pressure is continuously adjustable from the outside. The valve works reliably for tasks to minimise pressure surge (pressure surge limitation).
One special characteristic is its very compact design. The valve cone is soft-sealed (special flat seal). The valve is made of spheroidal graphite iron with a continuous epoxy coating > 200 µm, providing excellent protection against corrosion.
Thanks to its bell shape the controller automatically empties, ensuring that the medium cannot freeze (frost protection without subsequent emptying).
