Valve Selection
1. The application
2. The fluid
3. The flowrate
4. Working pressure
5. Test pressure
6. Setpoint
7. Maximum Temperature
8. Preferred control method• Electric• Pneumatic• Electro-pneumatic
9. Where will it be fitted• Inside • Outside• Safe area• Hazardous area• Vibration area
Always select valves based on flow NOT pipe size
• In order to make a selection the following need to be determined.
What is:
Material selection
• Ductile iron (SG iron)• Lube oil where higher than normal strength is required• Legislation (fire risks)• Pulsating pressures due to pressure spikes
produced by gear pumps
• Steel • High strength• High pressure• Specification requirements
• Stainless Steel • Corrosive environments (offshore)• Corrosive fluids
Flanged connection
• Selected to suit the customers needs
• Flanged 2” –16” ?• DIN• ANSI• JIS
Mode of Operation
• Mode of operation can be selected to suit customers piping
• 2 very different rotor constructions
• Modes can be easily changes in the field
Mode of operation
• On cold flow is from port 2
to port 1, Port 3 is blocked
• Rotor moves from port 3 to
port 1 on increasing
temperature
• Mode will be 31 for an
electric valve

Operation
•Continuously samples oil
•Oil enters top of MPD
•Oil travels through grid
•Oil exits bottom of MPD
OilIn
OilOut
Grid
Theory of operation
• Oil flows over a fine metal finger
grid, passing through a fine matrix of
holes.
• Metal particles become trapped by
the differential pressure over the
plates.
• The electric circuit is completed and
alarm sounds.
Installation Diagram
• Install in side stream of main oil supply line
• After pump, before filter, in bottom of oil line
• Install above crank case, if possible
• Install block valves before and after the MPD- use a bleed valve with the outlet block valve
• Use an adequate size orifice on the outlet of the MPD to prevent starving the equipment of oil
• Oil exits MPD into sump

Master safety shut down
• A Fail Safe System to Stop an engine, or
engine system, as a result of an unhealthy
condition.• Low oil pressure• Loss of coolant• Engine over-speed• High exhaust temperature• Excessive vibration
Vent to shut down principle
Vent to Shut down
• Vent to Shutdown means: When pilot
pressure is “vented”, the logic device will
trip,
• AND upon LOSS of pilot pressure the logic
device will trip.
