The Shand & Jurs Series 96900 Hydraulic Operators are used
specifically to operate Shand & Jurs Internal Safety and Shutoff Valves.
These operators are available in different models and supply the hydraulic
operating pressure required for valve actuation.
The Shand & Jurs Model 96900-01 Hydraulic Operator has a hydraulic hand pump
with a series of check valves which maintain pressure in the system and permit
multiple short strokes of the handle to build up the desired pressure. This
operator produces approximately 1000 psi of pressure. The standard operator
includes such items as pressure gauge, oil strainer and internal sediment basin.
The Shand & Jurs Model 96900-02 Hydraulic Operator is identical to Model 96900-01,
except that it includes an outside trip which manually releases pressure.
The Shand & Jurs Model 96900-03 Hydraulic Operator with Grad-U-Motor is operated
by applying air pressure (15 psig) into the chamber above the operator. As a
result the stem and the piston moves downward and depresses the check valve.
Now, the pump handle can be operated and the valves opened. Hydraulic pressure
is maintained on the valves holding them in the open position. Release of air
pressure automatically allows the check valve to open, thus reducing hydraulic
pressure and closing the valves.
The Shand & Jurs Model 96900-05 Hydraulic Operator with Deadman Control functions
the same as the standard operator, except the relief lever must be depressed
for operation. Releasing the lever, automatically releases the pressure that
results in valve closure.
