Operating Principle
GDV45-1 is an one spool valve. It is also an open center, 3 position 4 way valve. When spool is in neutral, flow from pump passes through neutral passage to tank. Produces very little pressure drop. When spool is move to “1” or “2” position, the neutral passage is blocked by spool. The flow from pump has to pass through the parallel passage to provide flow to spool’s metering to work port. The spool stroke is 7mm. For GDV45-1 mono-block valve, it cannot provide power beyond function.
2 Spool Mono-block Valve
GDV45-2 Two spool mono-block valve is also an open center, 3 position 4 way valve. When spool are all in neutral ,flow from pump passes through neutral passage to tank, and produces very little pressure drop. When one of the spool is moved to “1” or “2” position, the neutral passage is blocked by the spool. The flow from pump has to pass through the parallel passage to provide flow to spool’s metering to work port. There are options to choose for location of the inlet port and return port. There is also an option to have power beyond port. If first spool is moved to “1” or “2” position, then, the second spool’s neutral passage has no flow. The operator can operate two spools at the same time, but the speed of the controlled device is dependent on the load of the device.
