Brass ball valves with pneumatic

Valves provided with ball valves to actively winning customers. Our country has about 60 industrial plants and enterprises specialized in the production shut-off ball valves. Scope of the valve unusually high. Ball valves are used for installation of water supply systems, heating, gas, and pipelines transporting liquid fuel, water, steam and other aggressive and non-aggressive products. Managed ball valves of pipelines through an actuator, or electric pneumatic. For example, ball valves are equipped with pneumatic additional devices: braces provisions doubles, sensors, etc. As with electric and pneumatic actuator is set for ball valves are used on pipelines, as well as for large diameter pipes (greater than 150 mm). The main purpose of an actuator – automation control. As a rule, applies to poluoborotnoy pneumatic valves used for piping gas, oil, metallurgical and chemical industries, as well as in municipal and domestic economy. Depending on the equipment, ball valves with pneumatic perform various functions, including: the closing and opening of the flow, level control and flow rate of the working environment, ensuring integrity and so on. Structurally these cranes are building, the stop-ball element with a hole for passage of the flow, spindle, flywheel-driven. The main advantage of such a device is to remove hydraulic losses in the resistance when passing the working medium. Typically, building a ball made of brass, iron, steel and other alloys, while the self coupling device – made of stainless steel, as the most exposed element design. To ensure sealing ball valves are equipped with pneumatic sealing Teflon rings, which have an optimal resistance to dirt and wear. Sealing rings are pressed against the ball through the disc springs, which ensures long time use a ball valve in the interaction with low-or high-temperature environments. Among other things, ball valves with pneumatic unit equipped with limit switches and position sensors, with which you can automatically turn off the drive with the extreme positions of a ball that is carried out for a few seconds. The cost of ball valves with pneumatic stop bit more expensive than conventional brass ball valves, but all costs will be filled in the security, integrity, speed and ease of management.
