Cast Body Trunnion Mounted Ball Valves
B61
|
GENERAL INFORMATION Series B61 cast body trunnion mounted ball valve is designed according to API 608 and suitable for shutoff of various mediums. Comparing to floating ball valve, when under pressure, the ball is stable in it’s position and the force push the seat toward the ball to form a tightness, all the load come to the stem and bearings. Therefore, the seat is protected and low torque, stable sealing, long life time is assured. FEATURES • Bolted bonnet, two piece body for the size bellow 12” and three piece body for 12” and above Full bore for better Kv/Cv
• Blow-out-proof stem
• Pure PTFE, 25% carbon fiber reinforced RPTFE and metal seat available
• Anti-static devices for ball-stem-body
• Fire safe design
• Trunnion mounted ball type
• Flanged or butt welding ends
• Worm gear operator available
