Main Performance Specifications

Structure and Working Principle

This valve is connected by flange, in accordance with the GB/T 12232 standard.

The valve consists of a valve body, bonnet, disc, stem, stem nut, and handwheel, etc., and operates by rotating the handwheel to drive the stem nut, which in turn moves the stem up and down, lifting or lowering the disc to achieve the purpose of opening and closing, moving vertically with the flow direction.

Storage, Installation, and Usage Precautions

1. This type of valve should be stored in a dry warehouse and must not be exposed to the open air.

2. For long-term storage, regular maintenance should be performed.

3. This type of valve can be installed on any pipeline, and the handwheel can be positioned arbitrarily.

4. Before installation, the pipeline and valve cavity should be cleaned and pressure tested to meet the requirements. Before testing, the sealing surface should be wiped clean, and all bolts should be checked for tightness. Loose bolts should be tightened evenly, and the packing nut cover should be checked to ensure the packing is tightly pressed and does not hinder the stem from rotating.

5. After installation, the product should not be subjected to excessive external force.

6. The handwheel should be turned clockwise to close and counterclockwise to open.

7. The handwheel should not be used as a lifting device.

8. The working conditions should be consistent with the performance specifications.

9. Regular maintenance should be performed during use.
