Product Description

Product Description

Pneumatic Butterfly Valve

Product Introduction:

Pneumatic butterfly valves are valves that use compressed air to drive the actuator, which rotates the butterfly plate 90° via the valve stem to control the switching or flow regulation of pipeline media (liquid, gas, powder). They feature compact structure, small size, light weight, convenient operation, good sealing performance, and simple maintenance. They are widely used in industrial automation control systems in petroleum, chemical, power, water treatment, food and other industries. They are mainly divided into on/off type (2-position 2-way) and regulating type (2-position 5-way or intelligent positioning), which can realize remote centralized control or local control.

Product Features:

Pneumatic butterfly valves are characterized by simple structure, small size, light weight, quick and easy opening and closing (90-degree rotation), low flow resistance, good sealing performance (soft and hard seals are available), excellent regulating performance, and easy installation and automation control. They are widely used in petroleum, chemical, water treatment and other industrial fields, and can be used for on/off switching or flow regulation.

Product advantages:

Pneumatic butterfly valves are characterized by their simple structure, small size, light weight, easy installation, rapid and labor-saving opening and closing, low fluid resistance, and ease of automated control and remote operation. They are suitable for the shut-off and regulation of large and medium diameter pipelines. Furthermore, through soft or hard seals, various materials, and designs, they can adapt to different working conditions (such as high temperature, high pressure, and corrosive media), achieving energy saving, environmental protection, and low-cost operation. They are particularly suitable for modern industrial fields that require high efficiency and automation.

Product Applications:

Pneumatic butterfly valves are widely used in many industrial fields such as petrochemical, power, water treatment, food and beverage, pharmaceutical, metallurgy, papermaking, and HVAC. They are mainly used for the rapid opening and closing of pipeline media, flow regulation and cut-off, and control of liquid, gas, powder and other media. Due to their simple structure, light weight, convenient operation and easy automation control, they are especially important in applications requiring explosion protection, hygiene, high temperature and high pressure.
