TVN V202 Tilting Check Valve is the non-return valve preferred in pipe networks where faster closure is required. Through the coun- ter 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.

Tilting Check Valve Product Features

1. GGG40/50 Ductile Iron Body & Disc allows high impact and streching resistance
2. Double Eccentric / Double Offset Disc Design
3. Resilient Seated Type (Metal seated type optional)
4. Disc sealing ring EPDM as default. NBR or VITON options are available
5. Block moulded solid/one-piece T-shaped disc sealing ring extends drop-tight sealing life time
6. The open/close speed can be adjusted by modifying the counter lever length and weight. For adjustable shut off speed, TVN V203 Tilting check valve with hydraulic damper type is advised.
7. With extended shafts located on both sides of the body, lever position can be replaced on both sides. Two counter lever option is also available upon request.
8. Possible to install on horizontal and vertical pipelines with varied flow directions. It is necessary to mention the lever positioning requirements according to your project in order to arrange the lever side and position during prodution.
9. Easy to replace disc sealing ring without dismantling the valve from the pipeline and without dismantling the disc from the valve itself just by taking out the retaining ring through its bolts. It is easy to replace the disc sealing ring without any additional equipments
10. SS308/316 grade stainless steel welding seat on the body is manufactured through automatic welding machines and microfinished precise milling operation. When disc is fully closed, disc sealing ring applies equal pressure on every point on the welding seat.
