Product Description:

STAUFF SF series High Pressure Filters are designed for in-line hydraulic applications, with a maximum operating pressure of 420 bar / 6000 PSI. Used together with STAUFF SE series Filter Elements, a high efficiency of contaminant removal is assured. The high dirt-hold capacity of the elements ensures long service life and, as a result, reduced maintenance costs.

Options and Accessories:

Valve

• Bypass valve: Allows unfiltered oil to bypass the contaminated element once the opening pressure has been reached, a differential  pressure of 6 + 0,5 bar / 87 + 7.25 PSI ∆p is the standard setting. Other settings available upon request.
• Reverse flow valve: Allows reverse flow through the filter head without backflushing the element.
• Non-return valve: Prevents draining of the delivery line during element change.
• Multi-function valve: Opening pressure 6 +0,5 bar / 87 +7.25 PSI
• Bypass, reverse flow capability and non-return valve combined in one valve.

Clogging Indicator

• Standard actuating pressure: 5 -0,5 bar / 72.5 -7.25 PSI ∆p

Other actuating pressure settings are available upon request.

• Available indicators: Visual Electrical
