Two-piece of stem’s design facilitates easy assembly and field maintenance without the use of special tools Two-piece of systems makes disc feature being streamlined, minimizing fluid friction resistance and pressure loss.
2 Mounting Flange
Designed for easy adaptation of: lever handles, worm gears, pneumatic and electric actuators. (ISO Standard)
3 Stem Bushing
Low friction, lubricated bushing, absorbs side thrust load and reduced operating torque.
4 Body
One-piece design assures high strength. Wafer and lug style design. Accommodates ANSI, DIN, BS and JIS flanges. Long neck accommodates insulation
5 Flange Bolt Hole
Design accommodates to connect standard flanges of ANSI, DIN, BS and JIS.
6 Resilient Soft Seat
Constructed of special designed resilient elastomer, ensure excellent resiliency, low friction and longer seat life. Dove-tail type design seat tightly contacting to body and prevents seat from any bunching or collapsing when fluid pressure is applied.
7 Disc
The disc is precision finished to close tolerance on the OD and the flats Seating edge is a polished half ball for torque control.
9 Primary Sealing
Tight contacting between disc flat hub and seat flat hub ensures excellent sealing at way disc positions.. These “mate” with seat flats to give a highly efficient seal; prevents leakage into stem areas
8 Seat O-Ring
Two molded o-rings designed as one body with seat ensures tight sealing with no gaskets when connected with flange
10 Secondary Sealing
Accommodates tight sealing function both inside and outside of the valve, being applicable under the vacuum condition.
