Features
1.
Low torque, double eccentric
disc makes it leave the seat as soon as the valve opens, minimize the friction
and lower the torque. The cost is very competitive when using actuated such as
pneumatic and Electric actuators.
2.
Unique seat design, the sea t
is 100% exchangeable for all the valve of same size and seal type, no need to
change the body or other components. Removable seat retainer is the only step
to replace a new sea ring, unnecessary to disassemble the disc and stem.
3.
As the above features, it is
very easy to maintenance and comparing to total cost, it is very cost
efficiency.
4.
With double seat design, it is
strictly in accordance with API 607 specification. Bi-directional soft seal
design for zero-leakage in normal operation and a metal-to-metal seal after
fire
