QS-GF40-20 Rotary Joint
Introduction:
The Q series rotary joint or revolute joint adopts the Q face sealing structure, which can automatically adjust the center and automatically compensate. This type of rotary joint can be used for equipment with low speed and poor coaxiality. It has simple structure, reliable sealing and no lubrication, and are the most widely used rotary joint.
Working Parameters:
- Maximum speed: 150RMP
- Maximum pressure: 1.8MPa
- Maximum temperature: 200℃
- Applicable medium: saturated steam, superheated steam, superheated water
Code Meaning:
