GOETZE 851FL gunmetal flanged safety valve
Flanged version of the 851 gunmetal angle safety valve with stainless steel inlet and outlet bodies, DN 15 to DN 50 with DIN PN40 to PN100 or ASME Class 150 to 600 flanges, 0.5 to 50 bar, −60 °C to +225 °C.
The 851FL is the flanged version of the 851: the gunmetal body and brass trim of the threaded valve, fitted with stainless steel 1.4404 inlet and outlet bodies carrying DIN EN 1092-1 PN40 to PN100 or ASME B16.5 Class 150 to 600 flanges. It covers DN 15 to DN 50 and set pressures from 0.5 to 50 bar for water, air, gases and steam.
Bonnet versions, seals and lifting devices are the same as on the 851, from the open bonnet for neutral media to the double gastight bellows version, with temperatures from −60 °C to +225 °C. The valve is approved under PED, TÜV type test, ASME UV and CRN, and by DNV, LR, ABS, BV and RS for marine use.
Selection data we need
Medium and state, set pressure, required discharge capacity, operating pressure and temperature, back pressure, inlet and outlet size, flange standard and rating, seal material and bonnet version. For a replacement, the type code and nameplate data are enough.
