Performance
Advantages
- Very compact design and inline mounting for space saving.
- Mounting position is unrestricted.
- Three sizes provide great adaptability to the system.
- The inserted flow regulator cartridge can be purchased separately for easy service or for modifications to the original flow adjustment (ref. Catalogue RE 18329-61).
Description
Description
This valve is composed by a sleeve with an inserted poppet type check cartridge type VUH1.
Flow is always allowed to pass from A to B when pressure at A rises above the spring bias pressure and the ball is pushed from the seat. The valve is normally closed (checked) from B to A.
The inserted cartridge can be screwed-in or screwed-out with an Allen type key 6 or 8 mm, depending from the cartridge size.
