-
B. Connection
Platform under actuator can be customized according to requirements., which allows to install electric/pneumatic actuators by different standards.
-
C. Stem Bushing
The stem bushing acts as a support for the handwheel and drives the stem to rotate through the internal thread to lift the disc. Bronze and steel can be selected by requirements.
-
D. Stem
Different materials can be selected according to the working conditions. Hardness and corrosion resistance are the primary considerations.
-
E. Yoke
The yoke is composed of thickened steel plates, which is enough to support the disc, platform, and actuator.
-
F. Packing
Rubber and nylon packing material can effectively enhance the sealing between the gland and disc. Different materials can be selected according to the medium.
-
G. Body
The body is one-piece structure with wafer or lug style. Polyester is coated for excellent corrosion resistance. Shorter length greatly reduces production and maintenance costs of the valve. Different materials can be selected according to the working condition.
-
H. Disc
The polishing and chamfering design of the disc does not damage the seat. Different materials can be selected according to the medium.
-
I. Seat
