Summary Explanation of Valve Terminology
TWO Way Valve, Normally Closed:
Flow is from inlet to outlet when the valve is actuated.
Fluid in outlet line is trapped when the valve is deactivated.
THREE Way Valve, Normally Closed:
Flow is from inlet to outlet when the valve is actuated.
On deactivation of valve, outlet line is vented to atmosphere.
THREE Way Valve, Normally Open:
Flow is from inlet to outlet
in the deactivated valve condition.
Actuation of the valve stops flow from inlet to outlet, the outlet is then
exhausted.
FOUR Way Valve:
From inlet, flow is diverted to one of the outlets; outlet port that is not
active is vented to atmosphere.
Valve can be either spring return or two-position type.
FLOW Control Valve:
Allows free flow in one direction and controlled adjustable flow rate in
the other direction.
SHUTTLE Valve:
Allows flow from either input to the output.
PULSE Valve:
A unitized valve that converts a continuous supply of air into an outlet
pulse of air and then remains closed until the supply pressure is
exhausted.
