4001 Type Pneumatic O-Shape Cut-Off Ball Valve

4001 Type O-shape pneumatic cut-off ball valve cooperated with electromagnetic directional valves

and other pneumatic components, it can be used for cutting off or opening the pipeline medium in the

transmission pipeline of chemical industry, petroleum, pharmaceutical industry, papermaking, metallurgy,

sewage treatment and other industrial sectors, as well as in the pipeline medium of oil tankers and

tanker trucks.

It has the following characteristics:

1. Large flow channel capacity, and medium flow direction is not restricted.

2. Sealing valve seat adopts high quality plastic and other soft materials, with reliable sealing.

3. In addition to general gas, liquid, it is more suitable for high viscosity, as well as with fibrous and

suspended particles of the media.

Structure and action principle

Pneumatic O-shape cut-off ball valve is composed of O-shape ball valve, air cylinder actuator two

major parts and electrical components, as shown in Figure 1, the cylinder actuator is the O-shape ball

valve drive device, when the compressed air through the solenoid valve or other controllers into the

cylinder at one end, to promote the movement of the piston, through the piston rod, crank handle,

vertical shaft and other transmission mechanism, making the ball core to rotate 90 ° to the center of

the vertical shaft, so that the ball valve turned from the open (or closed) state to the closed (or open)

state. To achieve automatic control of the medium in the pipeline, there are two M101 (or G1/4) screw

holes on the side of the air cylinder type actuator, which can be used to install the solenoid valve

through the connecting plate, and there are two M101 screw holes at the top, which can be used to

install the two forming switches through the supporting parts. The center rotary top can be operated

manually with a wrench. See figure I.

1. The above structure length L, taking GB12221 as an example, can also be specified by the user

with other standards (including national standards) or other non-series.

2. When the user does not specify, the valve flange of our factory according to GB9113-2000, can

also be specified by the user for other standards (including international standards, such as ANSI,

JIS, API, etc.).

3. Matching actuators are based on domestic DA and ZSH double-action actuators, matching spring

reset (single-action actuator) or imported actuators must be specified.
