It is suitable for continuous or intermittent pressure applications and works well with post-mix carbonated beverage equipment as well as tea and coffee dispensing systems.
- Includes strainer for enhanced filtration
- ASSE 1022 approved dual check with atmospheric vent
- Can be installed in both vertical and horizontal positions
