Always check the specification PDFs for the exact product specification available in your region. 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. Application Areas Suitable for use in the following applications: CK3M, CKF3M, CK3MG, CKF3MG (metal valve seat) – steam. CK3T (PTFE valve seat) – steam, hot water. CK3R, CKF3R, CKF3RG ( Nitril or Fluorine rubber valve seat) – non-hazardous gasses, air, hot water, water, etc.
