OILPATH OP80 High-Pressure 6-Port Selector / Diverter Valve

Manually operated, lever-actuated 6-way 2-position selector valve. Cast iron body machined at Oilpath's new Adelaide facility in South Australia , hardened alloy steel spool with chrome/electroless nickel plating. Valve Body Finish Hand honed for the absolute minimum amount of Leakage. Pressure Rated to 210 bar (3,000 psi) working pressure with an 840 bar (12,000 psi) casting shock rating, and 118 L/min (26 GPM) rated oil flow.

How it works

The OP80 doesn't control flow rate or actuator speed — it's a directional switch that routes pressure from one pump to one of two separate downstream circuits.

• Oil from the pump feeds the OP80's inlet port.
• The lever selects which of two outlets gets pressurised — for example, straight to a motor, or across to a second control valve feeding a cylinder or other actuator.
• Return flow from whichever circuit is active runs back through the valve to tank.

Because the spool shifts all six ports together as one ganged unit, you get a full pressure-and-return swap between two circuits from a single lever throw — no second pump and no extra plumbing runs.

Why 6 ports

Two circuits each need a supply and a return line, plus the pump feed and tank line:

• 1 x inlet (pressure from pump)
• 1 x tank/return
• 2 x ports to Circuit A (pressure + return)
• 2 x ports to Circuit B (pressure + return)

Internally, a shuttle-type spool with a sleeve / land arrangement redirects these six connections as it shifts, with a detent to hold the spool in each selected position.

Handle linkage is repositionable, so orientation can be adjusted to suit cab or panel layout on different machines.

Real-world install example: adding a rock grab rotator from a spare circuit

Problem: Mick's excavator has no spare hydraulic circuit to run a newly fitted rock grab rotator.

Solution: An OP80 diverter valve repurposes an existing, less-used function — in this case the boom swing circuit — to also drive the rotator, without adding a second pump or re-plumbing the machine.

Components used:

• 1 x OP80 6-port diverter valve (ports A–F)
• 6 x hose adaptors
• 4 x new hydraulic hoses (2 for the boom swing cylinder, 2 for the rotator)

Install steps:

1. Disconnect the two original hoses running to the boom swing cylinder from the excavator's main control valve.
2. Connect those two original supply/return hoses to Ports A and B on the OP80 (direction doesn't matter — the machine's existing control valve still governs flow direction).
3. Run two new hoses from Ports C and D to the boom swing cylinder, restoring its original function through the diverter.
4. Run two new hoses from Ports E and F to the rock grab rotator's ports.

Operation:

• Lever in default position: oil flows A↔C and B↔D, powering the boom swing exactly as before.
• Lever flipped: Ports C and D close, locking the boom swing cylinder in place. Ports E and F open simultaneously, sending flow to the rotator instead.

Result: independent control of boom swing and rock grab rotator from a single existing circuit — the boom swing locks solid while the rotator is in use, and reverts to normal boom control once the lever is flipped back. This is a general-purpose technique: any underused function (not just boom swing) can be repurposed the same way to add a circuit for grapples, tilt buckets, augers, or other attachments.

Suits

Construction equipment, material handling, agriculture, mining, and manufacturing hydraulic systems needing an extra function added to a fixed-circuit machine.
