Trunnion mounted M&J ball valves are described and illustrated in this free brochure to deliver positive oil and gas pipeline shutoff.
The 6 to 42-in. ANSI 150 to 1500 designs feature a three-piece bolted body with internal trunnion blocks. They operate over -20° to +250°F./-29° to +121°C.
All incorporate a version of the patented “EN” style seat seal currently used on the M303 gate valve. A combination nylon and elastomer seal in the same face groove acts as the primary seal in both high and low pressure differential conditions. Seat rings are spring loaded for low pressure sealing. For high pressure sealing the differential area between the seat outside diameter and face seal enhance the seal.
Also emphasized and shown are the valve’s standard stem seal design which uses three seals to insure a positive seal. Models are cited to provide double block and bleed capability
