Product Characteristics
1.A good regulating performance;
2, accurate to 1/*0 ring opening laps;
3, the theoretical flow characteristic curve with an equal percentage (approximate) characteristics of ****0% valve authority, the actual flow characteristics such as linear;
4, with the opening lock function, non-property management staff can not change the settings;
5,can be easily and effectively on the pressure, flow regulation, supporting smart meters can easily display the working pressure and flow, to guide and record balance;
6, PTFE seal, seal performance, reliable, long life;
7, according to the pressure difference before and after the opening percentage and valves, can calculate flow through the valve;
8,. I have the internal components are stainless steel, copper alloy manufacturing, anti-corrosion performance;
9, within the lift stem no need to reserve the room for maneuver;
*0, Body Material: DN**-DN**0 gray cast iron; DN***-DN**0 carbon steel; DN**-DN*2 forging copper alloys.
