Product Details

Product description

The digital lock balance valve is a liquid pipeline flow regulating valve, its function is to adjust the flow conveniently and accurately, and effectively solve the problems of uneven cold and heat and hydraulic imbalance in the pipe network system. It not only has good adjustment performance, but also has opening degree display and opening function, and is widely used in heating and air conditioning systems and other liquid pipeline systems that need to adjust the flow. Since the valve is also equipped with a small valve for flow and pressure measurement, it can be debugged once with an intelligent instrument, so as to control the total water volume in the system within a reasonable range and achieve the balance of the pipe network.

Features
1. Linear flow characteristics, when the opening is large, the flow is large, and when the opening is small, the flow is small;
2. The valve body adopts a direct-flow structure, and the fluid resistance is small;
3. There is an opening percentage display, and the product of the number of opening turns and the pitch of the valve stem is the opening value;
4. There is a small pressure measuring valve at the inlet and outlet of the valve. After connecting with the intelligent instrument with a hose, the pressure difference before and after the valve and the flow through the valve can be easily measured;
5. The sealing surface is made of polytetrafluoroethylene, which has good sealing performance and long service life.
