Design features for
A. ACTUATOR MOUNTING FLANGE: Flange is designed for direct actuator mounting.
B. RETAINING RING: Retaining ring simplifies bearing and seal removal and ensures positive bearing retention.
C. BEARINGS: Multiple bearings substantially reduce operating friction and torque requirements eliminating any metal-to-metal contact, thus preventing shaft galling and freezing.
D. SHAFT SEALS: O-ring shaft seals insure positive sealing under the most adverse conditions.
E. SHAFT: Corrosion resistant, high strength steel shaft is easily replaceable.
F. SEAT O-RING SEAL: O-ring provides long lasting positive seal of seat inflation pressure.
G. MATERIAL SEAL: Land seal prevents material contamination of seat o-ring seal.
H. DISC/SHAFT: Integral disc and shaft with smooth, contoured surface provides minimum resistance to flow and reduces material buildup.
I. AIR INLET PORT: Oversized inlet port allows quick valve pressurization/
J. DISC: Smooth contoured surface assures extended seat life and disc is easily replaceable.
K. DISC SCREWS: Self-locking screws of high tensile steel provide strong link between disc and shaft, yet allow easy disassembly.
L. HOUSING: Rugged one-piece body fits standard 125/150 class ANSI flat-faced flanges and PN 10 metric flanges.
M. HOUSING GASKET: Die cut elastomeric gasket assures leakproof housing.
N. HOUSING BOLTS: High strength steel bolts maintain structural integrity of housing under the most adverse conditions.
O. SPLIT HOUSING: Rugged two-piece body fits standard 125/150 class ANSI flat-faced flanges and PN 10 metric flanges. Minimizes assembly time and allows for integral shaft and disc.
P. RESILIENT SEAT: Easily replaceable, the inflatable molded seat has a smooth contour locking design to minimize stress and hold the seat in place, eliminating any need for flange gaskets.
