產品特點：
頂裝手輪，當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
采用活塞式執行器，推力大，性能穩定。Piston actuator provides stable and high thrust.
結構緊湊，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
采用楔式石墨環加蝶形彈簧的填料組合，對填料的預緊提供動態補償，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，并能避免介質直接沖刷閥座密封面，使汽蝕閃蒸發生在閥籠的中心，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.
