3 piece ball valve − Series DM7000/DM8000
DM7000/8000 Series 3-piece ball valves feature an integrated cast direct-mounting flange designed to reduce the number of parts, the overall envelope dimensions, and hysteresis between the ball and actuator for control valve applications. The integrated mount also features an extension with a 1/8” NPT threaded side port that can be used for fugitive emissions monitoring, leak detection, fugitive emission diversion, as a Positive Pressure Seal, and as an emergency repair mechanism, enabling sealant injection through a button head check valve.
Series DM7000/DM8000 three-piece ball valves are ideal for process applications. The self-adjusting, live-load packing utilizes Belleville washers for positive preloading of the stem packing that compensates for environmental changes and wear, ensuring leak-free, bubble-tight sealing, maintenance-free operation, and long cycle life in both positive pressure and low pressure/vacuum sealing.
Resilient seat materials include RPTFE, TFM, UHMWPE, Tek Fil (Carbon Graphite/TFM), and 50/50 Stainless Steel Filled PTFE. DM7000/DM8000 is available with optional trims and configurations including V-ball control valve trims, cavity fillers, polished internals, vented balls, and other special cleaning. The flexible design of Series DM7000/DM8000 three-piece ball valves also enables in-line servicing and the ability for actuation equipment to be easily and safely removed while the valve is under full line pressure.
