產(chǎn)品特點：
頂裝手輪，當(dāng)自動控制失效時可以手動控制。Manual override for easy operation in the event of air supply failure
采用活塞式執(zhí)行器，推力大，性能穩(wěn)定。Piston actuator provides stable and high thrust.
結(jié)構(gòu)緊湊，閥門支架與氣缸直接連接，大大降低了閥門的總體高度，降低了閥門安裝空間的要求。Compact design with direct connection from the valve yoke to the actuator reducing the overall height in limited space installations
采用楔式石墨環(huán)加蝶形彈簧的填料組合，對填料的預(yù)緊提供動態(tài)補償，避免填料失效。High quality graphite packing with Belleville spring provides a continuous and stable sealing force.
多孔式閥籠具有減緩流速作用，并能避免介質(zhì)直接沖刷閥座密封面，使汽蝕閃蒸發(fā)生在閥籠的中心，避免對密封面的直接破壞。Multi hole cage provides velocity control and reduces the effects of flashing across the valve seat.
