Hand operated air control valves is composed of valve body, valve seat, valve disc, valve stem, valve cover and other parts. It is installed on oil, water and other pipelines, and by rotating the cylindrical valve disc, the size of the window area formed by the valve disc and the valve seat is changed, so as to achieve the purpose of regulating the flow. The opening and closing angle of the regulating valve is 60 degrees. , indicated by the opening indicator plate installed above the regulating valve. Medium temperature: 0～170℃.

The manual air valve is a control component in the pipeline fluid conveying system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, adjustment, throttling, check, shunt or overflow and pressure relief. The main features are to improve the heating supply conditions, save energy, and improve the hydraulic conditions of the network management. Common manual control valves are: 4H Series Hand Valve, 4HV Series Hand-Switching Valve, HV,HV400 Series Hand-Switching Valve.

As a two-way opening and closing and adjusting device for ventilation and dust removal pipeline, manual control valve is suitable for ventilation and dust removal and environmental protection systems in metallurgy, mining, cement, chemical industry, power generation and other industries.
