Wafer
- 2500 Series
Notes
1. 38-72 Contact Factory For Dimensions.
2. Dimensions noted above for 78 Series valves.
Consult factory for 76 Series dimensions.
BODY
Durable, solid ring type body is machined for accurate disc alignment.
Standard body wall thicknesses vary according to static pressure and flange
rating. Body is designed to withstand stresses imposed upon it, through
pipe flanges.
DISC
Fabricated type are precision machined and specially finished tolerances
prevent shaft distortion and disc misalignment. Ample metal is provided
in the hub to maintain rigidity and strength of the disc and its components.
SHAFTS
One piece or stub shafts.
BUSHINGS
Standard bushing materials are carbon/graphite or GR.BRZ. Other types
of bushing materials are available for specific applications.
FLANGE BOLT HOLES
Holes are located in valve body where optimum strength requirements provide
maximum support to the total valve assembly. Two or four body holes are
dimensioned according to USAS Code flange standards depending on valve
size.
FEATURES
1. Face-to-face dimensions to your requirements.
2. Valve can be supplied with reduced port.
3. Extensions for temperature
protection of instrumentation are available.

PACKING
Graphite is standard material in either plain or purged type stuffing
boxes. Purged boxes include lantern glands.
PACKING FOLLOWER
Provides uniform support to packing material and is precision machined
to stuffing box.
PACKING FOLLOWER STUDS
St. Stl. studs are precision fit into valve body for perfect alignment
of packing follower within stuffing box. They provide ample tensile strength
requirements.
SHAFT PINS
Precision taper pins, press-fit into disc and shaft, make this assembly
vibration proof.
As we are continually developing our products, the design of Shan-Rod
valves is subject to change without notice.
