    Description

    Pneumatic butterfly valve

    The Pneumatic Butterfly Valve is a robust, reliable and versatile valve that can accommodate a wide range of applications – from potable water and wastewater to seawater, HVAC and sanitary & chemical systems. The body of the valve is made from cast iron, ductile iron, aluminum stainless steel, CF8, CF8M, CF3M or double stainless steel (2507/1.4529). The disc is made from stainless steel (CF3M/CF3/CF8M) and has a one-piece disc/stem design which reduces the risk of leaking and pressure drops. It comes with an output torque of 10Nm to 8000Nm and offers control options like Double acting, Single acting normally closed, Single acting normally open etc. It also provides great flange accommodation including EN 1092 PN 6/PN10/PN16 ASME Class 150 , AS 4087 PN 10/ PN 16 , JIS 5K/10K or ISO5211 Top flange. Furthermore its temperature range is -40 °C to + 200 °C depending on material type and pressure. To make using this valve even more convenient it comes equipped with pneumatic accessories such as solenoid valves, limit switch boxes, filters E/P positioners and hand wheels. If you’re looking for reliable performance for your system then look no further than the Pneumatic Butterfly Valve!

    FAQs

    What is butterfly valve used for?

    A butterfly valve is an important type of control valve used in a range of industrial and commercial applications. The most common use of the butterfly valves is for controlling or regulating flow, with the ability to stop, throttle or vary fluid flow rate. The design features a circular disc which rotates around an axis within the valve body, meaning that it can be completely closed or partially opened to regulate flow. It’s common to find butterfly valves in HVAC systems, chemical process lines and water treatment plants; however they are also used extensively across other industries such as pharmaceuticals, power/renewable energy plants and oil & gas pipelines.

    What is a wafer-type butterfly valve?

    A wafer-type butterfly valve is a type of valve used in various industries for controlling and regulating fluid flow. It features two semicircular plates hinged together at the center, which form a disc that opens and closes like the wings of a butterfly. The plates are connected to a stem that is operated by turning the handle or wheel attached to it, which raises or lowers the disc as needed.

    What is a pneumatic butterfly valve?

    A pneumatic butterfly valve is a device used to regulate the flow of liquid or gas through a pipe. These valves are typically used on pipelines with large diameter openings, and they work by rotating a circular disc in order to stop or start material flow.

    Pneumatic butterfly valves have many advantages over other types of valves, including being lightweight, cost-effective, easy to maintain and adjust, highly reliable, and compatible with most types of fluid media. Additionally, these devices can be fitted with various accessories such as positioners and limit switches to better control the process.

    What are the applications of pneumatic butterfly valves

    Pneumatic butterfly valves are a type of control valve used for isolating or regulating the flow of a fluid. These valves are designed to provide fast-acting, bidirectional shutoff and have many applications in various industries.

    In chemical plants, pneumatic butterfly valves are widely used to regulate the flow of liquids and gases passing through pipes as well as control temperature, pressure, level and other process parameters. In power plants, these valves can be used to automatically adjust the fuel supply by measuring steam demand andńor controlling boiler feedwater levels. Pneumatic butterfly valves are also used in oil & gas pipelines for managing pipeline pressures during operation as well as preventing backflow when pumping equipment is offline. Similarly, they can be found in iron & steel production systems to control cooling water volumes inside hot rolling machines or pipe bends for energy conservation purposes. Lastly, these kinds of valves are frequently utilized by food manufacturers for reducing product waste during processing stages like crushing/mixing/aging when specific amounts must be maintained at each step of the production line.
