Valves Flashcards
(18 cards)
Are devices for controlling or regulating stark stop and direction as well as pressure or flow of a pressure medium conveyed by a hydro pump or stored in a container
Valves
Devices which influence the path taken by an airstream predominantly start stop direction of flow
Directional valves (way valves)
Types of valve actuation
Manual control
Mechanical control
Electrical control
Pressure control
Combine control
Valve is a treated for the entire duration of switch over until reset occurs
Continuous actuation
An impulse causes which over of the valve
Instantaneous actuation or impulse
Design characteristics of directional valves (two types)
Puppet valves
Slide valves
Two types of puppet valves
Ball seat valve
Disc seat valve
Three types of slide valves
Longitudinal slide valve
Longitudinal flat slide valve
Plate slide valve (butterfly valve)
Our devices which preferentially stop the flow in one direction and permit flow in the opposite direction
Non return valves
Three types of throttle relief valve
Supply air throttling
Exhaust air throttling
Throttle relief valve with mechanically adjustable throttle
Are elements which predominantly influence pressure or are controlled by the magnitude of the pressure
Pressure control valves
Three categories of pressure control valves
Pressure regulating valve
Pressure limiting valve
Sequence valve
Two types of pressure regulating valve
Pressure regulating valve without venthol
Pressure regulating valve with vent hole
Influence the volumetric flow of the compressed air in both directions
Flow control valves
Valves which permit or prevent flow infinitely variable simplified application stop cock
Shut off valves
Six ways of valve combination
Air control block
Nomatic equation with delays which over or time delay valve
5/4 way valve
Air operated 8-way valve
Variable impulse generator
3/2 way valve with binary reducing stage
Two types of time delay valve
Time delay of normally closed
Time delay valve normally open
Five types of non return valve
Check valve
Shuttle valve
Throttle relief valve
Quick exhaust valve
Two pressure valve
