型號選擇Model selection
    選用AW氣動執(zhí)行器時，先確定閥門啟、閉的扭矩，再根本閥門使用的流體介質(zhì)，增加安全值。對清潔、潤滑介質(zhì)增加20%
安全值；對水蒸汽或非潤滑介質(zhì)增加25%安全值；非潤滑的干氣介質(zhì)增加60%安全值；非潤滑氣體輸送的顆粒粉料介質(zhì)增加
*安全值。然后根據(jù)氣源工作壓力，查找雙作用式或單作用式輸出扭矩表，可得到準(zhǔn)確的執(zhí)行器信號。單作用式輸出扭矩
表中，zui小彈簧扭矩即為關(guān)閉閥門時的扭矩，zui大彈簧扭矩即為打開閥門時的扭矩。

AW pneumatic actuator used, make sure the valve opens, closing torque, and then do the valve using a fluid medium, added security value. For cleaning, lubricating medium increased by 20%
Security value; of water vapor and non-lubricating medium security value by 25%; non-lubricated dry gas media to increase 60% security value; non-lubricated gas transmission medium to increase the powder particles
* security value. Then the gas supply pressure of work, find the double-action or single-acting output torque table, available and accurate actuator signal. Single-acting torque
Table, the minimum time to close the valve spring torque is the torque, maximum torque is to open the valve spring torque.
