Dalian manual valve and self-locking manual control valve is mainly used for urban central heating, district heating, circulating water projects, thermal power plant pipe network and refrigeration and air conditioning projects, with the cut-off, throttle and regulate the flow of the role can be replaced Throttle orifice is a kind of throttling device that can change the aperture.
T40H Dalian manual valve features:
1, to improve the heating conditions: Those who use manual control valve of the line and the thermal point, you can press the design conditions for flow control, to achieve good temperature conditions, this valve than the valve , the valve regulating performance, It has approximately linear adjustment performance, therefore, the uneven heating and cooling of various heating buildings have been greatly improved.
2, energy saving: heat pipe network due to temperature and pressure imbalance, resulting in some tributaries too large, so that some buildings over temperature, the user had to open the window, a lot of heat wasted, due to the branch installed manual control valve to overcome The temperature and pressure imbalance, to avoid the window, to save energy purposes.
3, to improve the hydraulic conditions of pipe network: manual control valve can be controlled according to the rated flow, the pipe network over-flow reduction, so that the deterioration of the original water conditions have been some improvement.
