Product Description
The SPF type digital lock balance-valve is used for balancing the hydraulic regime of the liquid circulation network. It possesses the excellent characters about the control, the blockage, the opening rate display and the opening rate lock. It can save energy and electricity when it is used in the heat-supply system or the air-conditioning system.


Product Characteristics
1. A good regulating performance;
2, accurate to 1/10 ring opening laps;
3, the theoretical flow characteristic curve with an equal percentage (approximate) characteristics of 30-50% 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;
10, Body Material: DN15-DN300 gray cast iron; DN350-DN600 carbon steel; DN15-DN32 forging copper alloys.
