The Duriron Corporation
was founded in 1912 by Pierce D. Schenk and two
associates, William F. Hall and Richmond Pitman to
supply corrosion-resistant castings for the chemical
industry. The company name derives from its patented
alloy Duriron, which rapidly became an industry
standard. During the 1920s and 1930s Duriron became
a nationally-established producer of pumps and
valves. The company also began a move toward
off-the-shelf sales of its pumps and valves during
this time. This policy would begin to reap great
returns in the 1940s as Duriron's products became
more widely accepted in the chemical industry. The
name Durco was given to the pump and valve products
to emphasize the superior materials that they were
made of. Today, Flowserve Durco valves are among the
finest produced for the process industry.

Maintenance Free, Live Loaded Triple Seal Design Assures
Bubble Tight Shutoff Stem Seals Dynamically energized
shaft seals provide super safe operation. The primary
seal is formed at the disc hub by the spherical ball and
socket disc/liner seal. An independent secondary seal of
PTFE covered PFA convolutions on the disc stem enhances
sealing with its torturous no-leak path design. Finally,
the O-rings in the alloy gland follower offer added
protection from external media corrosion as well as
preventing leakage to the atmosphere. Leak tight sealing
is further assured by a compression spring which keeps
the dynamic pre-load force constant while energizing the
various components of the triple shaft seal design. This
dynamic live loaded shaft seal never needs adjustment.
Unique, energized seat design results in bubble tight
shutoff. The spherical ball and socket disc/ liner
design provides a 360 degree contact seat seal. The
rounded radius of the disc fits into the socket of the
machined liner and stays in constant contact with the
seat. The liner itself is recessed into the valve body
for added stability and to prevent possible leakage due
to cold flow or improper valve installation. A live
loaded elastomer seat energizer enhances sealing.
Isolated and protected in the grooved valve body, the
elastomer energizer operates independently of mating
flange torque for constant line seal performance.
