pneumatic butterfly valve procurement for precautions

In the morning, a customer wanted to purchase pneumatic butterfly valves. We asked many questions, but the customer was not clear. Now let’s summarize and share with you.

Before placing an order, the customer needs to provide the working condition requirements for product installation, the medium used, the temperature of the medium, and the nominal pressure rating of the pipeline, which are very important.

Pneumatic butterfly valves are relatively complicated automatic control instruments, and they also need to be equipped with various pneumatic components for use. Users can select accessories according to control needs and specify them in the contract. The following are the valve parameters we can provide for your selection
