FOR AN EXTRA MARGIN OF DESIGN CARE
A uniqu.e, design for
outstafidlng performance
The Mueiler® Resilient Seat Gate Valve. The
bi-directional design ensures a tight seal against
pressure up to 200 psi (1379 kPa) from either
direction. It combines the best of a butterfly
valve -- consistent, leak-tight shutoff and
throttling capability. And the best of a gate
valve -- full round flow-way for minimum
pumping power. Complies with AWWA
Standard C509.
The modified wedge disc is fully supported.
Its back side is flat and travels along a
machined surface in the valve body. Solid
guide lugs on the disc travel within channels
cast in the sides of the valve. This controls
movement of the disc either up or down
stream, and assures bubble-tight shutoff
regardless of direction of flow. To avoid
solids build-up in cavities and possible
stem binding, the center of the disc is
open on the back side.
The front side of the disc provides an
angular mounting surface for the resilient
rubber seat ring. The seat ring is molded
separately from the valve disc and mounts
securely to the disc with stainless steel
screws. The disc is machined to support the
seat ring and hold it in proper alignment --
there's no guesswork when installing the
seat ring, no slippage once in place.
For strength and mechanical stability,
the rubber seat ring is internally rein-
forced by a concentric steel ring.
By carefully designing the sealing surface
of the seat ring to closely conform to the
machined seating surface of the valve
body, positive sealing consistently occurs
with minimum torque applied to the
operating stem.
The bronze stem nut is cast
integrally with the cast iron valve
disc. This prevents twisting, bind-
ing or angling of the stem nut and
stem, and along with stable disc
support, assures accurate tracking
of the valve disc. The controlled
transition of the disc from fully
open to closed position makes the
Mueller Resilient Seat Gate Valve
suitable for throttling.
O-ring seals above and below the thrust
collar protect the operating mechanism
from the waterway and from external
contaminants. The space between the
O-rings is filled with a special lubricant
to permanently lubricate the thrust col-
lar and O-rings, providing easy stem
operation and protection from wear.
This lubrication system, in combination
with a thermoplastic anti-friction washer
above the thrust collar, provides efficient conversion of
torque to seating loads for easy operation and positive
sealing.
Mueller HP® Coating fully protects
the valve interior. It's a two-part
thermosetting epoxy, approved for
potable water and ideal for sewage
handling and industrial applications as
well. Mueller HP Coating serves as an
excellent physical, chemical and
electrical barrier.
