SVC/SHC Series
Sanitary Check Valves
The patented SVC/SHC Series are vertical and hori-
zontal check valves designed specifically for use in
biopharmaceutical and parenteral drug manufacturing
applications. They are the first check valves to follow
the valve design guidelines of ASME BPE 2009.
Since no spring, hinge, mechanical return mecha-
nism or stem is used, they are crevice free, have no
areas for particle entrapment, minimize particulate
shedding, and are CIP and SIP capable, and auto-
clavable.
The SVC with Teflon, PEEK and 316/EPDM discs
are for vertical up flow installations. The NEW SVC
with floating Polypropylene disc was specifically
designed for vertical downflow process outflow and
drain installations, and is another Steriflow industry
first. The SHC is designed with any disc for hori-
zontal line installations.
How it Works:
As soon as inlet pressure exceeds the weight of
the disc plus the outlet pressure, the disc will lift.
Process media flows under the seat and through
the disc perimeter holes to the outlet side of the
valve. As flow begins to reverse, the differential
pressure across the valve drops and the disc re-
turns to the seat, closing the valve.
F
eatures
• NEW - The first and only vertical down flow
sanitary check valve that is continuously self
draining
• Applicable for gas or liquids, and suitable for
CIP and SIP, and are autoclavable
• Elimination of springs or hinges speeds open-
ing time and eliminates particle entrapment
areas
• High flow rates with minimal pressure loss com-
pared with mechanical return check valves
• Low particle shedding properties compared with
sliding disc type or spring return check valves
• Unique design eliminates dead space and crev-
ices associated with spring check valves
• All wetted internal surfaces are mechanically
polished and electropolished to SF5,
20 Ra µin (.5 Ra µm), all external surfaces are
40 Ra µin (1 Ra µm),electropolished, other
finishes optional
• Sanitary tube weld ends and Tri-clamp ends
available
• Positive shutoff without the use of a spring
