Description
PRODUCT FEATURES
- Back flow-preventing valve with push-in fitting.
- Keeps pressure in outlet side. Permits air flow in one direction but checks the flow in the opposite direction, thus keeping the output pressure at a constant level.
- Able to maintain service pressure at-750mmHg (vacuum) and permit piping under low pressure.
- Ideal for vacuum retention and low-pressure applications.
- 4 options available
- CVC, straight.
- CVU, in-line straight.
- CVG, in-line reducer.
- CVF, bush.
