EXCVATOR solenoid valvae Set 423-4562 proportionalem solenoid valvae

Electro proportionalem valvae opus principium et deprehendatur:

Valvae potestate fluxus potest dividitur in duo genera:
Unum est switch imperium: aut plene aperta vel plene clausit, fluunt rate est vel magna vel parva, non est medium rei publicae, ut Ordinarius electro per valvulae, electro reversing valvulae.
The other is continuous control: the valve port can be opened according to the need of any degree of opening, thereby controlling the size of the flow through, such valves have manual control, such as throttle valves, but also electronically controlled, such as proportional valves, servo valves.
So the purpose of using proportional valve or servo valve is: to achieve the flow control by electronic control (of course, after structural changes can also achieve pressure control, etc.), since it is throttling control, there must be energy loss, servo valve and other valves are different, its energy loss is greater, because it needs a certain flow to maintain the work of the pre-stage control oil circuit.

Opus principium proportionalem solenoid valvae

Est secundum principium solenoid in-off valvae, cum potentia est off, vere premit core directe contra sedem, causando valvae claudere. coil
Cum electricity applicantur, electromagnetic vi generatae vincit vere vi et elevat core sic aperire valvae. Proportionalem solenoid valvae facit aliquod mutationes ad structuram de solenoidal valvae: et creates a statera inter vere vi et electro vis sub ulla coil current. In magnitudine et magnitudinem et in coil current vel magnitudinem ad electromagnetic vi et afficit ad plunger plaga et valvae foramen et valvae ostium (fluunt) et in coil current (potestate signo) est idealis linearibus necessitudinem.
Direct agens proportionalem solenoid valvae fluit sub sede. Medium influit ab sub sede et directionem vis est sicut electro vis et oppositum vi. Ideo necesse est ut ad maximum et minimum fluxus valores correspondentes ad operating range (coil current) in operating status. Proportionalem solenoid valvae de Drey fluidum est clausit (NC, Northmanni clausa genus) cum potentia est off.
