What is the normal position of a relief valve?
Closed Position
What is the pressure where a relief valve first opens called?
Cracking pressure
What does a relief valve limit in a hydraulic system?
Maximum Pressure
What is Difference in pressure between when a relief valve first opens and passes full pump flow through called?
Override
What is the type of relief valve that contains a chamber above its balanced piston that opens to reservoir called?
Vented Relief Valve
When a pressure reducing valve is vented, what is its outlet pressure?
Minimum Pressure
Pressure reducing valves are always drained in which way?
Externally
What is the condition of a pump if the pressure vent connection of a relief valve is opened back to the reservoir?
Unloaded
What is a specific order of operations called?
Operation Sequence
What should be included alongside a sequence valve if it is installed on a cylinder line?
Check Valve
What is the normal position of a back pressure valve?
Open Position
What is a valve being used to support a load called?
A counterbalance valve
If flow from secondary to primary is required, how high should be the unloading valve control pressure be above the spring setting?
150 PSI
What setting does the pressure in the outlet port of an internally drained sequence valve add to?
Spring Setting
Pressure reducing valve with internal check valve allows free flow in which direction?
Reverse direction
