Manual control valves are only applicable to steam or hot water pipes with nominal pressure < 1.6 MPa and < 2.5 MPa and medium temperature T < 200 and < 350 for regulating flow rate.




The manual control valve can be closed by rotating the hand wheel clockwise. At this time, the valve stem drives the valve disc down, so that the two conical sealing surfaces contact tightly until the pipeline is closed. The manual valve manufactured by our factory is suitable for the best energy-saving products of urban central heating or regional heating, mainly for regulating the flow rate.


Characteristics of manual control valve


1. To improve the heating supply, all the branches and thermodynamic points of manual control valves can be adjusted according to the design conditions to achieve good temperature conditions. This kind of control valve has better regulation performance than gate valve and globe valve, and it has similar linear regulation performance. Therefore, the cooling and heating phenomena of heating buildings have been effectively improved.


2. Energy saving: due to the imbalance of temperature and pressure in the heat pipe network, some branch flow is too large, so that some building temperature is too high, users have to open windows, to achieve the purpose of energy saving.


3. Improve the hydraulic condition of network management: Manual control valve can control according to the rated flow rate, reduce the flow rate of network management overrun, and make the original water condition deterioration to a certain extent.
