I do not agree with the premise that full-port is synonymous with full-bore. However, valves may eventually wear out from use and develop a leakeither between the inside and outside of the valve or, when the valve is shut to stop flow, between the disc and the seat. Valve positions are operating conditions determined by the position of the disc or rotor in the valve. Update Cancel. W8 W12 W16 W However, not all round or spherical discs are rotors; for example, a ball check valve uses the ball to block reverse flow, but is not a rotor because operating the valve does not involve rotation of the ball.
