Marine bronze immersed pneumatic butterfly valve

Overview

Marine bronze immersion pneumatic butterfly valve is the executive unit in the pneumatic unit combination instrument. It comes from the signal of the regulating instrument to change the cutting and circulation of the medium. The product has large operating force, novel valve body design, small flow resistance, and large rated flow coefficient. , Excellent sealing performance. Therefore, it is widely used in the automatic control and remote control communication of the production processes of various industrial sectors such as petroleum, chemical industry, textile, food, foam and other industrial sectors.

Features

It comes from the signal of the regulating instrument to change the cutting and circulation of the medium. The product has large operating force, novel valve body design, small flow resistance, and large rated flow coefficient. , Excellent sealing performance.

working principle

Marine bronze immersed pneumatic butterfly valve is composed of actuator (pneumatic and electric) and corner butterfly valve body, which is connected by a bracket in the middle. Take the GIQ type as an example: the actuator is composed of a dual-air cylinder as the main body, which receives the signal pressure of the air source (0.4 ～ 0.6MPa) controlled by the two-position four-way solenoid valve as the power, and changes the air flow direction through the control element to execute the cylinder drive The butterfly valve performs opening and closing movements. Can be classified according to different materials and different actuators, suitable for -25 ～ 200 ℃ media
