The valves operate progressively and can be used in installations with e.g. air, water, oil, and other aggressive media. The valve housing, nipple and cone are in non-corrosive steel with seal material in fluorinated rubber (FPM/FKM) or EPDM, alternatively perfluor rubber (ISOLAST®).
• Connection (Inlet/Outlet) 15/25, 20/25, 25/32, 32/40, 40/50
and 50/65, male thread (ISO-G)
• Opening pressure 4 – 22 bar (0.4 – 2.2 MPa) for DN15-20, 2.0 – 22 bar (0.2–2.2 MPa) for DN25-50. Can be ordered with optional opening pressure within the given intervals.
