• Similar as wafer type except a pair of the thread bolt hole in way of the upper and lower sides for easy maintenance of adjacent pipe.
• Easy handling and light weight.
• Less quantity of hole and easy installation.
• Keep liquid remained during repairing adjacent pipe.

The High-performance Design
The axis of disc rotation is double eccentric offset to the seat ring.
When the disc rotates, it unseats at a small turning angle by this cam effect.
This prevents seat abrasion and provides perfect seal for a long period.
