12 Swing type GS GS 015 DN /4-20 Features and Advantages: Little dimensions and low weights. Easy mounting between flanges with any packing. To be installed with vertical (only upwards) or horizontal flow. For downwards fluids spring version is to be used. No leackage with soft seat; acc. to API 598 with metallic seat. Low head losses. NOTE 1: In these pages you will find the description of the standard swing check valves. On request different materials can be supplied (Aluminium- Bronze, Hastelloy, Monel, Duplex, etc.). NOTE 2: The standard GS valve cannot be installed between flanges with spirometallic packings. For this application the body finishing must be modified and the O.rings removed.
