Marine pneumatic ventilation butterfly valve

Overview

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

Pushou Marine Pneumatic Butterfly Valves are widely used in pipeline systems of ships, ships, cruise ships and marine engineering. Due to the limitations of pipeline space and environment on ships and marine engineering, the operation and environment of ordinary butterfly valves cannot fully meet and adapt to their needs. This product is small in size, has limited space, and can be operated remotely. It can also be connected to the remote control system for remote control operations. For example, when the air supply and power supply on the ship are out of source, this product can also perform butterfly valves on the spot. The opening and closing work, the resource collection of this product is simple and convenient (compressed air), the butterfly valve is sensitive to opening and closing (opening and closing speed 1-3 seconds), the remote control system is equipped with original parts such as opening and closing status signal display, fault alarm and low pressure alarm, etc. Can be connected to the microcomputer through the interface for remote control operations. Pushou products are composed of remote control box, control button, pneumatic drive head, local operation drive mechanism, stroke limit switch, valve body, butterfly plate, valve stem, seat ring and other components. The products can be provided in compliance with ISO standards and JIS standards. And GB standards and various specifications for users to choose.

Features

1. Novel design, reasonable, unique structure, light weight, quick opening and closing.

2. It has a small operating force, easy operation and dexterous labor saving.

3. Use suitable materials to meet low, medium and high medium temperature and corrosive medium.
