Pneumatic valve is to install a pneumatic actuator on the valve. The actuator is driven by compressed air to realize the opening and closing of the valve.

the

Application of pneumatic valves: mainly used in explosive environments such as petroleum, natural gas, chemical industry, electric power, printing and dyeing, mining, pharmaceuticals, etc.

the

Procurement of pneumatic valves: It is not perfect in the current market economic environment to meet the procurement requirements only by specifying the specifications, categories, and working pressure. Because of the competition of products, pneumatic valve manufacturers carry out different innovations under the concept of unified design of pneumatic valves, forming their own corporate standards and product characteristics. Therefore, when purchasing pneumatic valves, it is very necessary to put forward technical requirements in more detail and coordinate with manufacturers to reach a consensus as an attachment to the pneumatic valve procurement contract.

the

Installation: This type of valve should generally be installed horizontally in the pipeline.

the

1. When installing the pneumatic butterfly valve, pay attention to the flow direction mark on the valve body, so as to avoid the wrong flow direction and affect the use.

the

2. Pneumatic butterfly valves can be installed vertically and horizontally within a horizontal range of 180°. Do not place the pneumatic actuator upside down.

the

3. The crank arm of the pneumatic actuator has a square head structure, which is used as a manual device. In case of failure, remove the air source pipe and directly use the manual wrench to realize manual operation.
