CTSD系列彈簧薄膜回轉(zhuǎn)式執(zhí)行器，即使在的供氣壓力（1Bar）下，也能通過氣、水、基于礦物的液壓流體介質(zhì)來平穩(wěn)運(yùn)行。該執(zhí)行器的工作溫度可低至-60℃（-76°F）高達(dá)200℃（392°F）。
The CTSD Spring-Diaphragm Rotary Actuators are designed to be used with minimal pressure when necessary and can be operated by air, water, mineral-based hydraulic fluid.Our housing and cover are constructed with a ductile iron/carbon steel casing that is coated with a polyester powder coating. Our independent media room is equipped with a Buna-N diaphragm reinforced with polyamine fabric. These actuators are designed to work in temperatures as low as -60℃ (-76°F) and as high as 200℃ (392°F).
