PNEUMATIC BUTTERFLY VALVE
Pneumatic butterfly valve is a type of flow control device consisting of a disk with two opposite sides, each having an inclined periphery, installed inside the valve body. When air pressure acts on one side and presses down the conical surface of the disc, the valve opens.
Product introduction:
Pneumatic butterfly valve is a type of butterfly valve. It consists of a disc with two opposite sides, each of which has an inclined periphery and is installed inside the valve body. The diaphragm is placed horizontally on the top and held in position by the adjusting screw. When driven, air pressure acts on the diaphragm and tilts it, opening or closing the flow through the disc. It can be easily installed on 1.5 inch pipe. It has the surface treatment of brass, bronze and stainless steel, so that it can match any decorative style, and can easily adapt to various installation environments.
Pneumatic butterfly valve is a kind of self pneumatic butterfly valve with small volume and light weight, which is made of plastic. The valve body and disc of the product are also available in a variety of materials. Its working principle is to use the meshing disc floating on the spring to realize the sealing effect of closing or opening according to the pressure difference (differential pressure) on both sides of the pipeline.
Pneumatic butterfly valve is a type of PVDF pneumatic valve. It is also called pneumatic disc valve, pneumatic disc control, etc. It is mainly used to control the flow of gas, steam and liquid in industrial processes. Its working principle is: when the pressure difference between the process requirement value and the flow control pressure (pressure gradient) in unit time reaches a certain value, the disc moves according to its directional function to achieve a fixed pressure difference between the working chamber and its sealing chamber.
Product advantages:
Pneumatic butterfly valve is a kind of mechanical device that regulates and controls the flow of liquid and gas in the pipeline through manual operation. The pneumatic butterfly valve has a disc, which is arranged on a shaft, and the two halves move in one direction respectively. On the surface of the disc, there are two holes (each cylinder hole). When these valves are opened, they allow fluid to flow through them while closing all other routes so that material can only be transferred through one route. Grooves for this purpose control the movement of the valve disc and improve performance during use.
Pneumatic butterfly valve is a kind of pneumatic valve, which allows full flow in one direction and provides cut-off in the other direction. Using pneumatic technology, a large control area can be driven from a small motor position. The lever can be preset to the open or closed position, or it can be left in the middle position for automatic operation. Pneumatic butterfly valves can be used to control compressed air or vacuum (or both).
Product design:
Pneumatic butterfly valve is an innovative valve design with flexible rubber diaphragm to ensure uninterrupted flow control. This allows precise airflow regulation within the system, preventing back pressure and reducing energy costs while still maintaining maximum safety and reliability.
The pneumatic butterfly valve has a self sealing internal design, which can be adjusted quickly and conveniently within its operating range. The valve is manufactured with an internal stainless steel housing and nickel plated brass trim. Metal parts have good corrosion resistance to harsh chemical environment and high process temperature.
Wafer butterfly valve with pneumatic actuator including cast iron and stainless steel body material for choice. SS 304 disc or SS 316 disc available. EPDM seal, VITON seal and PTFE seal options. High torque, large size range. Suitable for water, oil, air, steam, gas control.
