带阀杆密封螺纹衬套的 AVR 截止阀和带阀杆密封金属波纹管的 AVB 截止阀。
GEA shut-off valves (AVR, AVB, AVR/AVB also with electric) are designed for installation in industrial heating and refrigeration systems. The stem sealing is provided either by a threaded bush (AVR type) or by a threaded bush with an additional metal bellows (AVB type) to ensure a complete hermetic sealing. Electric actuator AVR/AVB are powered by an electric motor connected to the stem. The valves can be operated by a hand wheel or a ratchet attached to the stem. By turning the stem clockwise, the valve disc is lowered onto the valve seat, thereby closing the valve. Counter-clockwise rotation of the stem raises the valve disc, opening the valve. Shut-off valves should only be operated in the fully open or fully closed position. When the valve is fully opened, it is possible to replace the threaded bush and the seal. The valves are equipped with a back seal. When the valve is fully opened it is possible to replace the threaded bush and the sealing.
