The Shand and Jurs Biogas Model 97190 3-Way Safety Selector Valve
The Shand & Jurs Biogas Model 97190 3-Way Selector
Valve permits the safe and efficient maintenance
of redundant pressure relief systems without any
process interruptions. This is achieved through the
smooth operation of the valve, allowing full flow from
the primary system, to be diverted to the secondary
system while providing positive shut off for the isolated
system. The switching of the systems through a
single valve only requires one connection into the
pressure vessel, allowing the quick change over and
avoiding the costly depressurizing of the system.
The 97190, 3-Way Selector Valve, is available in sizes
from 2” to 10” with ANSI B16.5 150 lb. and 300 lb.
raised face or ANSI B16.5 150 lb. flat face flanged
connections. The high flow internal configuration
is designed to provide maximum capacity under
emergency conditions, while providing positive shutoff
for the isolated branch. Operation during “switchover”
is performed effortlessly with the low friction design
of bearings, seats, and seals.
A wide selection of body, rotor and stem materials are
available to suit the needs of your specific application.
Available materials of construction include 304SS,
316SS, cast steel, and aluminum. Consult the factory
for other material selections. The standard seat
seal material is Teflon. Consult the factory for other
material selections.
Operators are provided for all sizes. The standard
operator for the 2” through 10” valves is the nut drive.
Worm gear operators with hand wheels are optional
(Consult Factory).
