Cartridge Valve
a type of valve used in manifolds
Types of Cartridge valves
Screw-In valve
Slip-In valve
Five benefits of cartridge valves:
Lower installation Cost Smaller Package size Alleviate external leakage Easier maintenance Lower noise
Three difference in Slip-In and Screw-In
Max flow rate
Screw-In has 100% of system inside block
Screw and no Screw
Screw-In Valve
Low Flow
Slip-In Valve
High Flow
Proportional Valves
Control and vary pressure, flow, direction, acceleration, and deceleration electricall from a remote position.
Spool valves
Three tyeps of Proportional valves:
Proportional pressure control valves
Proportional flow control valves
Proportional direction control valves
Spool Types
Symmetrical
Nonsymmetrical
Symmetrical Spools
Restricts both flow paths equally, which enables meter-in and meter-out.
Nonsummetrical Spools
Restricts only one path, which only allow for meter-out.
Never mount with solenoid on ____.
