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 VRCA (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 > 250 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).
