Non-slam check valves can be divided into three types according to their structure: lifting non-slam check valves, swing non-slam check valves and butterfly non-slam check valves.

1. Lifting non-slam check valve is divided into vertical and horizontal.

2. Rotary non-slam check valve can be divided into three types: single-lobe, double-lobe, and multi-lobe.

3. Butterfly non-slam check valve is straight-through.

The above non-slam check valves can be divided into threaded connection, flange connection, welding connection, and clamp connection.


Structure:

According to the structure, it can be divided into three types: lifting non-slam check valve, swing non-slam check valve, and butterfly non-slam check valve. The lifting non slam check valve can be divided into two types: vertical and direct. Rotary non-slam check valve can be divided into three types: single-lobe, double-lobe, and multi-lobe. The butterfly non-slam check valves are butterfly double-lobe, butterfly single-lobe and the above non-slam check valves can be divided into four types in connection form: threaded connection, flange connection, welding, and clamping connection.
