-
Low weight and
short laying length produce savings in initial
cost, space requirements, and installation when
compared to full-body, swing-type check valves.
-
Contour of body
provides a short and straight flow path that
generates very little turbulence. Additionally,
the spring-loaded discs are designed with very
low cracking pressure which reduces the amount
of energy required to open the valve.
-
Shut-off is
achieved via the fully automatic,
spring-assisted discs that close near zero flow
velocity. The lightweight, split disc design
creates a positive shutoff prior to flow
reversal and helps to keep slamming and surges
to a minimum.
-
The spring and
discs are designed to allow the discs to lift
linearly before pivoting to avoid the disc heal
from scrubbing the sealing surface. Also, discs
are equipped with cast-in shock bumpers that
help to reduce wear and tear on internal
components.
-
The retainer-less
body design eliminates potential leak paths to
the environment so there are no body emissions.
-
Board, lapped
sealing surface
(metal) meets or
exceeds API 598 test requirements. Resilient
seats (Viton/Buna) ensure a bubble tight seal.

Low weight & short length produce savings in
initial cost, space requirements, & installation compared to full-body, swing
