BV2 Trunnion Mounted Ball Valve
Aceco's Model BV2 Trunnion Mounted Ball Valves combine advanced trunnion design and quality manufacturing for superior performance in manifold valve applications. For high-pressure service up to 15,000 lbs. psi, the Model BV2 is available in nominal sizes from 2" to 12".
Because of its trunnion design, the Model BV2 provides up to a 70% reduction in operating torque, compared to similar floating ball valve designs. This reduction in torque is an important consideration on production manifolds. Torque is reduced because the load pressure on the valve is exerted on the trunnions instead of the seat assembly. Since the trunnions rotate in a low friction bearing, the valve is considerably easier to operate than floating ball valve designs. Lower torque operation enables the use of smaller, lighter weight gear operators/actuators and hand wheels, allowing for additional cost savings and ease of operation. Some of the other Model BV2 features include:
- Double block and bleed capability for simple seat integrity check
- Threaded seat retainer enables the valve to be installed in either direction and permits removal of piping from either end at full rated working pressure, with the valve closed; also eliminates the potential for blowouts
- Lubrication fitting and lube channel integrated into stem design to help minimize stem/bonnet corrosion and eliminate stem freeze-ups
