Marine lug pneumatic butterfly valve 

Overview

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. The valve adopts a center-line structure, which has a tighter and tighter sealing function and reliable sealing performance.

2. Sealing pair material is made of stainless steel and nitrile oil-resistant rubber, with long service life.

3. The rubber sealing ring can be located either on the valve body or on the butterfly plate. It can be applied to different characteristics of media for users to choose.

4. The butterfly board adopts a frame structure with high strength, large flow area and small flow resistance.

5. The overall baking paint can effectively prevent rust and can be used for different media as long as the sealing material of the sealing valve seat is replaced.

6. This valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation, nor is it affected by the position of the space. It can be installed in any direction.

7. The valve has a unique structure, flexible operation, labor saving and convenience.
