Model 950 is designed as a
cost effective and versati Ie
solution for most knife gate
applications. The key design
feature is the two lug single
piece cast body, which
ensures optimum functional
capabilities with lower body
weight and cost. The design
offers a choice of either
cast or plate superstructu re
(yoke) wh ich also perm its
interchangeability between
manual and pneumatic
actuators. A cast body is more
rugged and offers better leak
tightness than a fabricated or
cast two-piece body; it also is
superior to cast valves with
stainless steel lining which are
more susceptible to corrosive
and erosive wear.
