The ring valve is a straight way valve with T-branch. On product passage it remains open.
It is equipped with an integrated pig catcher.
In piggable systems this pig catch unit which can be used from both sides offers a wide
variety of applications. Besides filling this valve can also produce a blister-free
positioning of product between two pigs.
In this valve all dynamic seals are integrated in a valve unit which can be easily
replaced. This valve unit is spring-closing, i. e. the valve closes automatically on
loss of control air.
Available sizes are DN 50 up to DN 150 (2” up to 6”)
- Compact installation size
- All dynamic seals are integrated in the easily replaceable valve unit
The ring valve opens a T-shaped outlet into a piggable pipeline. On this opening process a
ring-shaped element slides crosswise to the pipeline and thus produces the opening. This
ring is also the pig catcher.
