HIGH PRESSURE MOTOR VALVE REPAIR MANUAL<br />
INTRODUCTION<br />
SCOPE<br />
This instruction manual contains repair information for the standard 1" and 2" <strong>Kimray</strong> <strong>High</strong> <strong>Pressure</strong> <strong>Motor</strong><br />
Valve and the 2” through 6” Piston Balanced <strong>High</strong> <strong>Pressure</strong> <strong>Motor</strong> Valve.<br />
DESCRIPTION<br />
The <strong>High</strong> <strong>Pressure</strong> <strong>Motor</strong> <strong>Valves</strong> are all actuated with a pneumatic actuator which features an open yoke and<br />
travel indicator. The actuators are reversible between pressure opening and pressure closing configurations.<br />
The standard <strong>High</strong> <strong>Pressure</strong> <strong>Motor</strong> Valve employs a ball and cone seat configuration. The Piston Balanced<br />
<strong>High</strong> <strong>Pressure</strong> <strong>Motor</strong> Valve shuts off with a resilient seat.<br />
OPERATION<br />
The <strong>Kimray</strong> <strong>High</strong> <strong>Pressure</strong> <strong>Motor</strong> <strong>Valves</strong> require no more than 30 psig to operate. The pneumatic pressure<br />
drives a diaphragm against a return spring. When pneumatic pressure is relieved, the valve shuts.<br />
MAINTENANCE<br />
Maintenance should be performed on a regular basis. An initial inspection interval of 12 months is recommended.<br />
Depending on the service conditions and the condition of the valve, the inspection interval may be<br />
decreased or increased. The valve can be repaired without being removed from the piping.<br />
WARNING<br />
Before performing any service be sure that the valve is fully isolated and that all pressure upstream and<br />
down has been relieved.<br />
• Use bypass valves or fully shut off the process<br />
• Be sure that any operating or instrument gas lines have been disconnected.<br />
• Never assume that a check valve is fully blocking the downstream line.<br />
• Never tighten any fitting or the main connections to the regulator while there is pressure on the line.<br />
To get the long service you have come to expect from <strong>Kimray</strong> products, always use GENUINE KIMRAY<br />
PARTS when doing repairs. Remember, parts made to less than <strong>Kimray</strong> specifications don’t save you<br />
money!!!<br />

SPECIAL CASES<br />
SEAT PULLERS<br />
Some times the Seat does not come out<br />
with Stuffing Box and Cage. We have a<br />
couple of options if this happens.<br />
First Option:<br />
If the Seat is the only part that stays stuck<br />
in Body:<br />
1. Use the wire seat pullers and insert<br />
them in seat (Fig. 8.1).<br />
2. Slide a wrench or small rod<br />
between the wire Seat Pullers<br />
3. Tap up pulling the seat out<br />
(Fig. 8.2)<br />
Figure 8.1<br />
Second Option:<br />
If the Stuffing Box comes out by it self<br />
leaving seat, Ball & Stem and Cage stuck<br />
in Body.<br />
1. Thread Seat & Cage Removal Tool<br />
on to Cage (Fig. 8.3)<br />
2. Tighten flange down against Body<br />
3. Pull Case and Seat out of Body<br />
(Figure 8.4)<br />
Figure 8.2<br />
Figure 8.3 Figure 8.4<br />
The other end of the tool is used in case<br />
just the Seat stays in Body.(Fig. 8.5)<br />
1. Thread Seat & Cage Removal Tool on<br />
seat<br />
2. Tighten flange against Body<br />
3. Pull the seat out by turning the handle<br />
in a clock wise direction<br />
