Flowserve E51/52 Flanged Ball Valve

Flowserve E51/52 Flanged Ball Valve

Flanges Integral to the valve body, flanges are rated ASME Class 150 for the E51 and ASME Class 300 for the E52. Flange dimensions are to BS EN 1759-1/ASME B16.5 and face to face lengths are to BS EN 558-2 table 6/ASME B16. 10. Alternative metric flanges are available to BS EN 1092-1 (PN16/40).

Body Construction The valves are all of one-piece design, and are available in either low temperature carbon steel or stainless steel as standard. Other materials are available.

Stem The blow-out proof stem design is of a larger diameter than normal and is retained by a tamper-proof split ring. The stem is 316 stainless steel as standard, but other options can be supplied. Primary stem seals are PTFE in trapezoidal section, and secondary seals are PTFE chevron rings. Alternatively graphite seals are supplied for fire-safe and high temperature applications.

Ball The ball is manufactured from 316 stainless steel as standard, and other materials, as required.

Seats A range of seat materials is available to suit a wide variety of applications and include virgin PTFE, 15% glass-filled PTFE, Fluorofill, PEEK and metal (graphite impregnated 316 stainless steel). (Pressure/temperature ratings can be found on the back page of the data sheets).

Body Seals ½ ” to 2” (15-50mm): Virgin PTFE. 3 ” to 6” (80-150mm): 15% glass-filled PTFE.

Automation All Enviro-Safe valves are designed to be simply and easily actuated.
