TVN - Model V106 -Double Eccentric Butterfly Valve

SHARE

The TVN V106 Double Eccentric Resilient Seated Butterfly Valve is a prominent choice in water network systems. By utilizing a disc design where the center is shifted along two axes, the valve significantly reduces operational torque, thereby minimizing friction in the disc sealing area and extending its overall service life. This innovative engineering approach makes it a suitable solution for various applications requiring efficient and reliable valve operations. With extended durability and enhanced performance, this valve meets the critical needs of modern water management systems.

TVN V106 Double Eccentric Resilient Seated Butterfly Valve is the mainstream product type preferred in water networks. Through 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.

GGG40/50 Ductile Iron Body & Disc allows high impact and streching resistance
Double Eccentric / Double Offset Disc Design
Resilient Seated Type
Disc sealing ring EPDM as default. NBR or VITON options are available
Block moulded solid/one-piece T-shaped disc sealing ring extends drop-tight sealing life time
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. Iit is easy to replace the disc sealing ring without any additional equipments
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.
