Mueller®
Resilient Wedge Gate Valve
Features
of the 2"-12" Resilient Wedge Gate Valve:
|
Triple "O"-ring stem seals
-- The top "O"-ring serves as a dirt seal. The
lower "O"-ring
isolates the stem thrust collar bearing area from the water
way. The upper two "O"-rings can easily be replaced
in the line while the valve is under
pressure in the open position.
Forged bronze stem and thrust collar
-- This time-tested Mueller design has two thrust washers
and has repeatedly proven its superior strength over cast stems.
Bronze stem nut
-- The nut is electrically-isolated from the iron in the wedge
for corrosion resistance. The nut is held tightly
in place to resist stem binding.
Polymer wedge guide bearing caps
-- Provide a bearing interface between the rubber-encapsulated wedge and the interior epoxy coating, contributing
to easy operation and removing wear as a concern.
Oversize, full round, smooth bottom flow way -- The bottom has no grooves or recesses that could collect
sediment or debris and compromise the seal. Accommodates full-size
shell cutters with ample clearance during tapping operations.
Superior epoxy coating
-- The valve is covered inside and out with the Mueller HP® Epoxy, complying with AWWA C550 and
certified to NSF 61.
Integral legs
-- Flats cast in the bottom of the valve body let the valve
stand upright in storage or during installation. |
