Regarding the selection of pneumatic ball valves

Thread Content

For an 8-inch, 150LB valve with a torque of 762 nm (1143 nm if using a safety factor of 1.5), what torque value should I use for a single-acting cylinder?
Reply #22022-09-12
Rigid seal or soft seal? Soft seal: 240; Rigid seal: 270. For a torque safety factor of 1.5 times: 270

The valve torque is over 700; is the cylinder torque also 720?
Reply #42022-09-13
270 is an abbreviation for the actuator (bore diameter of 270), not torque

If the results are not satisfactory, you can try using our patented ball valve.
