Medium-controlled backpressure regulators are simple control valves used to relieve pressurised systems of excessive pressure in a controlled way. These valves do not require pneumatic or electrical control components to work reliably. They are easy to install and maintain.
The UV1.9 backpressure regulator is a seat-controlled spring-loaded valve used to protect pump systems or other pressurised vessels or pipelines. The set pressure is continuously adjustable from the outside.
Its special feature is its very compact design. The valve cone has a hard seal (metallic seal). The valve is manufactured from deep-drawn CrNiMo stainless steel featuring excellent corrosion resistance.
Thanks to its angled form the valve drains automatically, ensuring that medium cannot freeze in the valve (Frost protection without special draining).
Pilot lines are not required.
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 (metal sealing cone - 0.1 % Kvs value).
