When replacing a faulty TXV what information is needed?

• Refrigerant

• System capacity

• Type of connections

  eg. Flare/Solder

• Internal/Externally equalising

Critically charged systems use certain RMDs such as...

• capillary

• TEV

• AEV

• Float valve

A TXV is a flow control valve which meters what refrigerant?

• Subcooled liquid

• Superheated vapour

• Saturated Vapour

An oil separator is basically a ...

• Float valve system

• Pressure return

• Solenoid valve

• Safety switch

Opening pressure on a TXV is

• Bulb pressure

• Evap pressure

• Screw pressure

• Spring pressure

The difference between an internal TXV and external TXV is the

• Evap pressure

• Suction pipe pressure

• Pressure at either side of Evap

• The bulb pressure

If bulb pressure is lost the TXV would

• close

• open

• stick in current positioin

• explode
