Benefits and Features

Reliably Prevents Backflow
Check valves utilize a mechanical sealing mechanism to prevent backflow.
By providing a tight seal, backflow is safely avoided.
Easy to Use
There are no restrictions on installation orientation (horizontal, vertical).
After the valve has closed, it opens again at the slightest pressure differential.
Long Service Life
TLV’s unique center-guided disc (CK3MG, CKF3MG, CKF3RG) offers greater durability.
