Minimum bores for full-opening valves shall not be less than those specified in Table 1
6.5 Valve operation
The purchaser should specify the maximum pressure differential (MPD) at which the valve is required to be opened by the lever, gearbox or actuator. If not specified, the pressure rating as determined in accordance with 6.1 for material at 38°C (100°F) shall be the MPD.
The manufacturer shall provide the following data to the purchaser:
- the flow coefficient K,;
- the breakaway thrust or torque for new valve;
- the maximum allowable stem thrust or torque on the valve and, if applicable, the drive train.
6.6 Pigging
The purchaser shall specify the requirements for piggability of the valves. Clause A.4 may be used to assist.
