Application
Static balance is achieved by pre-setting of opening position,which could be read by scale on two circles (one for basic circle and another for ?ne adjustable circle). DN 5-50 valves have two pressure testing connectors, while DN65 and above have two plugs on the valves, two testing connectors in the package to be replaced on jobsite. The valves may be installed in either the supply or the return pipe, and normally on the return pipe.
Inspection And Storage
Inspect valves while receiving the valve. Put all valves carefully on the ground. When lifting, the valve should be tightly secured and never lifted by the bronze or stainless steel trim.
The valves should keep clean and dry before installation. If storage period more than six months, the surfaces of the seat (when provided) should be coated with a thin ?lm of FDA approved grease. Do not expose rubber seat to sunlight or ozone.
Installation
The ?ow arrow on the valve must be the same to the ?ow direction in the pipe system.
The valve must be installed in a run of pipe of the same nominal size. All valves are recommended to be installed as ?g below. To ensure ?ow measurement accuracy it
is essential that the piping on the inlet and outlet sides is straight and has a minimum length equivalent to 5 diameters at inlet and 2 diameters at outlet as shown. If the valve is located on the outlet from a pump then it is essential that the straight pipe length between pump outlet and valve inlet is a minimum of 0 diameters.
維修
江森靜態(tài)平衡閥不需要常規(guī)的日常維護(hù)。如果閥桿與壓蘭之間有泄漏，可以擰緊一下壓 蘭填料。拆下手輪鎖母，去掉手輪。按要求擰緊壓蘭螺栓。不要過度擰緊以免 影響正常操作。（閥門沒有上密封功能，不能帶壓去除壓蘭）。重新安裝手 輪，檢查閥門是否正常操作，是否有泄漏。
Maintenance
No routine maintenance is required. It is possible to tighten the gland while leakage happen between stem and gland Unscrew the hand wheel nut, remove the hand wheel, tighten the gland screw. (The valves are not provided with top sealing. Removing gland without relieving the presssure is prohibited.) Reinstall the hand wheel, check the valve for smooth operating and no leakage.
