Make a comparison to butterfly valve with the same rated value of plug valve, stop valve, brake valve, ball valve and membrane valve, butterfly valve has less requirement of weight and volume. Installment and maintain charge cost much less.

The requirement of torque value of high-performance butterfly valve reduces markedly. For example, the piece weight of ANSI 150# flange 8 is only 45 pound, and its maximum torque valve reaches 1500 pound/inch. While plug valve weights 319 pound, and its torque valve reaches 12500 pound/inch. Ball valve weights 158 pound, and its torque valve reaches 6400 pound/inch. As for the corresponding rated value of brake valve, it weights 310 pound. And it needs actuated equipment as actuator. Therefore, comparing to other valves, High-performance butterfly valve only needs diminutive actuated equipment.

Because of Bray/McCannalck valve is confirmed that it is a high performance of economy, it’s a best choice of high pressure working condition.
