Investment Casting also can be called "precise casting" or [lost wax casting" or "dewaxing casting". The casting materials can widely use and no limitation for product shape as well as complex structure. The most important characteristic is the close tolerances control, reduced machining allowances, and fine surface finish.

Balance valve is a special function of the valve, it has a good flow regulating characteristics, the relative flow and the relative opening of a linear relationship. Accurate valve opening instructions, the minimum reading of the valve full opening of 1%. Reliable opening lock memory device, the valve opening changes can be restored to the original lock position. There are cut-off functions, the installation of the balance valve eliminates the need to install a stop valve. A quantitative measurement and adjustment functions, the system debugging, commissioning personnel and special intelligent instrumentation man-machine dialogue, the balance valve to adjust, you can achieve system hydraulic balance. Application occasions 1. Boiler or chiller boiler or chiller installed in parallel, if the flow of each unit and its rated flow inconsistent, the unit will not be efficient point of operation, affecting the unit to maximize efficiency. In this case, balance Valves should be installed at each boiler or chiller so that each unit can achieve the designed output to ensure the safe and normal operation of each unit. Chiller connected to multiple cooling towers, each cooling tower should also be installed balance valve. Community heating pipe network District heating pipe network often by a boiler room or heat station to several buildings heating. The main pipe, main pipe and the main pipe connected to the entrance of the building pipe composition. Because each building is located at a distance from the heat source, the lack of effective equipment to eliminate the residual head pressure in the near-loop will cause the flow distribution to fall short of design requirements, resulting in overheating of the proximal end and overheating of the distal end. The balance valve should be installed on each main pipe and each branch pipe to ensure the flow balance between the main pipe and each building. 3. HEATING AND ACOUSTIC PIPELINES IN BUILDINGS HEATING AND ACOUSTIC PIPELINES IN BUILDINGS To meet energy conservation requirements, all risers and manifolds need to be designed to meet the design flow requirements. At this time, balance valves should be installed on the manifold, mains, risers and manifolds. 4. Thermal Station In a system where the thermal power station or boiler room supplies hot water to several thermal stations, a counterbalance valve shall be installed on each side of the loop of each thermal station for the required water flow to be obtained by each station. In order to ensure that the secondary loop water flow is the design flow, the balance valve should also be installed on each secondary loop side of the thermal station.

Its application scope can be wider after using the new equipment and advanced technology. In heat processing industry, investment casting can be used for those products which difficult to choice the materials, or materials not easy to form a shape, as
