VPS江森静态平衡阀，DN1 - 0

特点 Y型设计静态平衡阀具有优秀的调节和截止功能，其流量特性曲线为等百分比特 性。拥有内置测量孔板和测量接头。可通过调节手轮来准确调节流量，拥有精确

到1/10圈的位置指示。江森自控阀门从全开到全关需要 整圈。转动手轮，指示器显示开 度情况。实测压差与流量关系不会随着手轮开度变化。

VPS江森静态平衡阀，DN - 00

特点Y型设计江森静态平衡阀具有优秀的调节和截止功能，其流量特性曲线为等百分比特 性。拥有内置测量孔板和测量接头。通过调节手轮以达到要求的流量。开度指示

器显示zui终的阀门设置。压差与流量之间的关系不会随着手轮的设置而变动。 从全开到全关，DN -1 0需要 整圈，DN200-2 0需要12整圈，DN 00需要1 整 圈。基本圈数和精确到1/10圈的显示能够准确指示开度情况。

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.

维修

江森静态平衡阀不需要常规的日常维护。如果阀杆与压兰之间有泄漏，可以拧紧一下压 兰填料。拆下手轮锁母，去掉手轮。按要求拧紧压兰螺栓。不要过度拧紧以免 影响正常操作。（阀门没有上密封功能，不能带压去除压兰）。重新安装手 轮，检查阀门是否正常操作，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.
