Working principle and purpose of the product:

The Dalian style manual control valve can be closed by rotating the handwheel clockwise. At this time, the valve stem drives the valve disc to descend until the two conical sealing surfaces come into contact and the pipeline is strictly prohibited from being closed. The manual regulating valve produced by our factory is suitable for energy-saving products such as voice strip centralized heating and district heating, mainly for regulating flow rate.

This manual regulating valve is suitable for regulating flow in steam water pipelines with nominal pressures ≤ 1.6MPa and ≤ 2.5MPa and medium temperatures of 1-200 ℃ and ≤ 350 ℃.

Product Structure Features:

1. Improve heating conditions:

2. Energy saving: Due to the imbalance of temperature and pressure in the thermal pipeline network, some branch flows are too large, causing high temperatures in some buildings. Users have to open windows, wasting a large amount of heat energy. Due to the installation of manual regulating valves in the branches, the temperature and pressure imbalance is overcome, avoiding windowed households and achieving the goal of energy conservation.

3. Improving the hydraulic conditions of the pipeline network: Manual regulating valves can control the flow rate according to the rated flow rate, reducing the excessive flow of the pipeline network and improving the degree of deterioration of the original water conditions to a certain extent.
