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.
