MTBV has advantages to shut off every fluids ranged from low temperature to high temperature. The seal capability has been enhanced by attaching two arms to two shafts as new invention by Supero Seiki. With a gland packing structure, the shaft seal is available under high pressure, which ensures a long-term use in being adjusted tightening.

In addition, friction resistance in terms of high temperature range is reduced in order to process an anti-seizure by way of overlaying in 13 Chrome or in stellite at a tip of disc. Compact design with box made of SCPH2 as well as disc made of SCPH2 under high temperature / high pressure are as our advantage.

We’ve succeeded in decreasing the torque by way of getting a tip of disc sphere as well as a seat of box flat under line contact.
