Relief Valves And Self-Acting Pressure Relief Valves

These valves are constructed in such way that their entrance and exit are on the pipeline axis(axial type). Increased pressure on the pipeline opens the valve through its membrane, and the excess of  fluid returns to the provided places. Pressure relief valves are made ofstainless steel, steel, brass and platic. They are used for pressure grades up to Pmax=40bar, acids, alkalis, water and technical  gases. They are produced in sizes from DN10 to DN25.

Type:EPV-ASN

They are used to keep inlet pressure in the system constant. This type of pressure relief valves is used for diesel fuel,petrol, oils  etc. Construction of these pressure relief valves allows easy adjustment of the opening with specific span of pressures at the entrance. In case of exceeding the system pressure, the valve opens and the excess of fluid flows back into the tank through the output flange.They are made for pressure grades up to Pmax=300 bar and in sizes DN10- DN50.

Type:EPV-UCP

They are used for technical gases, water vapour or water during constant consumption. They are made of stainless steel, structural steel, polymers. Pipeline fitting can be flanged or threaded. The main function of relief valves is to keep output pressure constant. Maximum output pressure is Pmax=40bar, minimum output pressure is Pmin=0.5bar.They are produced in sizes from DN15 to DN200. As for their construction, they can be single or double-seat valves.
