Products Details

Pneumatic V-type ball valve is a valve controlled by pneumatic actuator, which is widely used in various industrial fields. The following is a detailed description of the pneumatic V-type ball valve:

Structure and working principle:
The pneumatic V-type ball valve is composed of the pneumatic actuator and the ball valve, which controls the opening and closing of the valve by rotating the spool. The spool is designed with a special shaped V-notch for precise flow closure and control. When the spool is rotated 90 degrees, the valve is fully opened or closed, which makes the valve easy to operate, small size and reliable sealing.

Main features:

Small fluid resistance: The resistance coefficient of the pneumatic V-shaped ball valve is equal to that of the pipe segment of the same length, which is suitable for the flow of various media.
Simple structure, small size: the valve design is compact, easy to operate and maintain.
Reliable sealing: The sealing surface material is widely used in plastic, good sealing, and has also been widely used in vacuum systems.
Easy to operate: open and close quickly, from full open to full close only need to rotate 90 degrees, easy to remote control.
Wide range of application: small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
Application field:
Pneumatic V-type ball valve is widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rockets and other departments, as well as People's Daily life. It is especially suitable for the control of suspension and solid particles containing fiber or small solid particles, so it is widely used in textile, petroleum, chemical industry, paper making, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial automatic control systems.

Technical parameters:

Nominal diameter: 25 ~ 400 mm.
Nominal pressure: 1.6 ~ 6.4 mpa.
Materials: Body materials include WCB (carbon steel), ZG1Cr18Ni9Ti (stainless steel), ZGOCr18Ni12Mo2Ti (duplex stainless steel), etc.
Sealing material: PTFE, stainless steel, hard alloy.
Installation and maintenance:

Before installation, the whole machine should be tested according to the specified signal (electricity or gas), and the line can be installed after passing the test.
Before preparing for connection to the pipe, rinse and remove any remaining impurities from the clean pipe to avoid damaging the seat and ball.
During installation, do not use the actuator part of the valve as the lifting point to avoid damage to the actuator and accessories.
Type:

Floating pneumatic V-type ball valve: The ball is floating, under the action of medium pressure, the ball can produce a certain displacement and tight pressure on the sealing surface of the outlet end to ensure that the outlet end is sealed.
Fixed ball pneumatic V-type ball valve: The ball is fixed, does not move after pressure, suitable for high pressure and large diameter valves.
Elastic ball pneumatic ball valve: The ball is elastic, suitable for high temperature and high pressure media.
The design and application of pneumatic V-type ball valve make it have an important position in the field of industrial control, and can meet the needs of a variety of working conditions.
