Pneumatic stainless steel ventilation butterfly valve (for RTO gas)

　　Pneumatic Ventilation Butterfly Valve Product Overview

　　The butterfly valve is processed into a sealing ring by the same material as the valve body, and is electrically or pneumatically driven. The applicable temperature depends on the material selection of the valve body. The nominal pressure is ≤0.6MPa, which is generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation and medium flow.

　　Pneumatic ventilation butterfly valve features

　　1. The design is novel, reasonable, unique in structure, light in weight, and quick to open and close.

　　2, the operating torque is small, easy to operate, labor-saving and smart.

　　3. Use suitable materials to meet low, medium and high dielectric temperatures and corrosive media.

　　Pneumatic ventilation butterfly valve actuator

　　The new series of AT-type pneumatic actuators are double-acting and single-acting (spring-return), gear transmission, safe and reliable; large-diameter valves adopt series AW pneumatic actuator fork-type transmission, with reasonable structure and large output torque. There are double acting and single acting.

　　1. Gear type double piston, large output torque and small volume.

　　2. The cylinder is made of aluminum and gold materials, which is light in weight and beautiful in appearance.

　　3. Manual operation mechanism can be installed at the top and bottom.

　　4. The rack-and-pinion connection can adjust the opening angle and rated flow.

　　5. The actuator can be equipped with electric signal feedback indication and various accessories for automatic operation.

　　6, IS05211 standard connection provides convenience for the installation and replacement of the product.

　　7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ±4° at 0° and 90°. Ensure synchronization with the valve.
