Counterbalance valve is a special function of the valve

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.

Meticulous division of labour, consecutive processes, professional of manufacture and high standard equipment ensure the high quality of the machine. 

Factory introduced high precision maching tools, with the equipment of cutting machine tools, heattreating facilities, check out test sets and painting facilities, the processing ability for middle and large size machine, reach a high level in plastic industry while the quality if the machine is ensured at the same time. 

Middle size machine can produce differnt design of crates and containers, videos can be provided. 

Vertification of many year's market application, optimal combination configuration, stable, reliable and durable system with the characteristics of high efficiency, energy saving, low voice and strong power. 

The strengthening design of template is carried out through multiple times of optimization design of major components such as template, based on the analysis of finite element software, which both guarantee the lifetime of template and protected mould. 

High rigid template adopts the structure with coexistence of installation screw hole and T-shaped groove. 

The tie rod of each machine model has passed the test by professional testing organization, which means that, the deflection of tie rod is within reasonable scope while guaranteeing the operation of machine.
