WALTER TDCV Tilting Disc Check Valve is the non-return valve preferred in pipe networks where faster closure is required. Through the counter lever and weight attached to its shaft, ensures a soft open depending on the speed of the flow and maintains reduced closing times when flow stops. With its disc design where the center is shifted in two axis, this leads to a big improvement on decreasing operation torque values, lowering the friction on disc sealing area and extended service life.
feature:
1.Double Eccentric / Double Offset Disc Design
2.Soft seal provides a drop tight closure
3.Tilting disc - when adjusted accordingly requires very small forward pressure drop to open
4.Adjustable lever and weight to assist the valve when closing to avoid water hammer - acts also as position indicator
5.All seals and coatings with contact to the medium are approved for drinking water
6.Low torque requirements during operation
7.Txhua txheej ntawm lub cev thiab disc sab hauv & sab nraud nrog qhov nruab nrab ntawm 250 microns. Cov txheej thickness ntau dua yog muaj thaum xav tau.

4.Testing: EN 12266-1
5.Size Range: DN150 - 2000
6.Pressure Rate: 1.0 Mpa; 1.6 Mpa; 2.5 Mpa ua
7. Kub: -10 ° C ~ 80 ° C
8.Coating: Fusion Bonded Epoxy Resin.
Nthuav Qhia
1,Tilting Disc Check Valve, Slanted Seat Check Valve, Butterfly Type Check Valve, Non-slam Check Valve
2,Tilting Disc Non-slam Check Valves are installed in pumping applications to prevent backflow in the system. All interior parts are stainless steel or coated with drinking water approved epoxy, lever and a weight fitted to the shaft end to help close the valve before the flow changes direction or a hydraulic damper that makes sure the disc does not slam into the seat and cause water hammer.
