Spring Loaded Disc-type Check Valves

Overview
TLV CK series check valves are ideal for nearly all types of fluid processes with their high sealing performance in both vertical and horizontal piping and their rapid open-close mechanism.
- CK3M/CK3T/CK3R
Select among 3 types of sealing surfaces, depending on the temperature and fluid requirements. - CKF3M/CKF3R
Wafer-construction (flangeless) check valve body is sandwiched between pipe flanges. - CK3MG/CKF3MG/CKF3RG
Center-guided disc and large flow area ensure superior durability and capacity.
Select the check valve with features best suited for the application.

Spring Loaded Disc-type Check Valves
The spring and disc construction allows the valve to open at the slightest pressure differential, and the valve seat provides an extremely tight seal. The valve closes the instant backpressure exceeds line pressure.

Large-sized (up to 100 mm) Spring Loaded Disc Check Valves (with Center-guided Disc)
The center-guided disc eliminates the tilting effect that can cause sticking in large-sized disc-type check valves, thus ensuring operation and offering increased reliability.
