Valves conform to ANSI B16.18 and ANSI B16.22. Maximum Pressure/Temperature Ratings: 300 psi (20.7 bars) - 250^oF (121^oC).

安装
INSTALLATION

1. 在需要平衡的设备的回流管线上或按照计划安排安装阀门。
   Install valve on return line of equipment to be balanced or as shown on the plans.
2. 为了实现最大的精确度，流量测量阀应该位于没有限制的直线管道上，在测量阀上游5倍管道直径长的距离内和下游2倍管道直径长的距离内不能有连接件（弯头，阀门，三通，等等）。如果平衡阀位于循环泵的下游，则泵和平衡阀之间的距离要有10倍的管道直径长度。
   For maximum accuracy, the flow measurement valve should be located in an unrestricted straight pipe run so that no fittings (elbow, valve, tee, etc.) is closer to the measurement valve than 5 pipe diameters upstream and 2 pipe diameter downstream. If a balancing valve is located downsteam from a circulation pump, allow a distance of ten (10) diameters between the pump and balancing valves.
3. 系列CSM-61M1是双向的，应该安装以确保容易连接仪器、调节设置，并启动记忆装置。1个DN3 NPT塞紧端口安装在每个测量阀上，如果需要能够用作排放端口。
   Series CSM-61M1 flow measurement valves are bidirectional and should be installed to insure ease of hooking up meter, adjusting setting and enabling memory device. A ¹/₈" (3 mm) NPT plugged port is installed on each measurement valve and can be used as a drain port if needed.
4. 焊接端口阀门适用于不需要拆卸的软焊接管线，采用低温焊料(204^oC)。可以使用其他焊料如95/5锡锑(238^oC)，但是，在使用时，必须特别注意防止阀座受到损坏。采用更高温度的焊料将会损坏阀座材料。
   Solder end valves are designed to be soft soldered into lines without disassembly, using a low temperature solder (400^oF)(204^oC). Other solders such as 95/5 tin antimony (460^oF)(238^oC) can be used, however, extreme caution must be used to prevent seat damage. Higher temperature solders will damage the seat material.
5. 在用明火加热时不要直接施加在阀体中心上。过热可能损害阀座。焊接后，填料螺母可能需要紧固。
   Apply heat with flame directed away from the center of the valve body. Excessive heat can harm the seats. After soldering, the packing nut may have to be tightened.
6. 热焊料连接只能用在焊料能够正确流动的地方。过热可能扭曲黄铜铸件。
   Heat solder joints only to the point were solder will flow properly. Excessive heat may distort brass castings.

1. 放松记忆螺丝。
   Loosen memory screw.
2. 用扳手将指示器旋转到指示器板上的开位置。不要用力超过这个点。
   With wrench, turn indicator to open position on indicator plate. Do not force past this point.
3. 连接、排气和预备压差表。参阅压差表附带的使用说明。
   Connect, vent and prepare the differential gauge. Refer to instructions furnished with the gauge.
4. 在获得初始压差读数后，参阅根据压差和阀门设置而得的流量表。如果流量超过规定，将指示器旋转到关闭位置，注意压降和阀门设置，并从流量表中确定新的流量。一旦确定正确的流量设置，则将记忆止动装置朝着指示器板的开启位置顺时针方向旋转，直到记忆止动环触到指示器板为止。不要用力超过这个点。紧固记忆螺丝。参阅图1。这个装置或系统现在已经平衡，并且记忆设置。
   After initial pressure differential reading is taken, refer to flow rate charts to obtain flow rate based on pressure differential and valve setting. If flow rate is in excess of that specified, turn indicator towards closed position, noting pressure drop and valve setting and determining new flow rates from flow rate chart. Once correct flow rate setting has been established, slide memory stop clockwise towards open side of indicator plate until memory stop ring hits indicator plate. Do not force beyond this point. Tighten memory screw. Refer to Figure 1. The unit or system has now been balanced and the memory set.
5. 记忆设置后，断开压差表。
   After memory is set, disconnect differential gauge.
