Pressure Limit:

Hydraulic fluid up to 3,000 psi (206 bar); model-specific port size and return-port pressure limits apply.

Service:

Hydraulic oil; high-pressure OEM directional control for applications including hydraulic presses and pilot systems.

Range:

Approximate oil flow: 1/4-3/8 in ports 5 GPM at 20 ft/s; 1/2-3/4 in 14 GPM; 1 in 25 GPM; 1-1/2 in 62 GPM. Higher-velocity values and Cv vary by series.

Proof Pressure | Burst Pressure:

Proof: 1.5x working pressure except return port. Burst: 2.5x working pressure except return port; return-port rating varies by model.

Options:

Hydraulic working pressure up to 3,000 psi (206 bar). Spring-return and OEM flow-pattern options vary by 6140/6180/6900/6940 series.

Temperature Range:

-40 to +250°F (-40 to +121°C).

Piping Connections:

Main-valve port size varies by series: 1/4, 3/8, 1/2, 3/4, 1 and 1-1/2 in; confirm size availability by model.

Overpressure, Burst, Vacuum Service:

Return-port back pressure max 250 psi (17.2 bar). Pressure drop: 14 psi (0.96 bar) at 20 ft/s; detailed values vary by model.

Wetted Materials:

Rotor: hard-anodized aluminum; pressure seals: brass; shaft: stainless steel; body/housing: anodized aluminum; bearings: carbon steel; Buna-N O-rings, PTFE backup rings.
