YFL bellows seal globe valves adopt bellows seal as stem seal to avoid leakage from gland, so they are widely used in applications which has poisonous, flammable, explosive working medium to avoid disasters and losses caused by gland leakage.
YFL bellows seal globe valves are also used in steam and thermal oil system to avoid energy losses due to gland leakage.
There are three kinds of bellows seal globe valves as below:
1. Straight type bellows seal globe valves according to DIN standard
2. Straight type bellows seal globe valves according to ASME standard
3. Angle type bellows seal globe valves according to DIN standard
4. Y type bellows seal globe valves according to ASME standard
