Technical features
- Differential crush pressure is 3000 psid (210 bar).
- The flow path is Port 2 to Port 1 only.
- Installation directly above the subplate will protect the entire valve stack from particles.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Surface type element features a 304 stainless steel mesh media. All internal components are 304 stainless steel.
- Surface Type elements have a 40 micron nominal rating (63 micron absolute).
- Surface Type elements are designed to capture errant particles that may not be trapped in the main system filter or particles resulting from a component failure.
- With a correctly assembled system, Surface Type elements will be unnoticed during regular operation, but will provide protection from sudden component failure.
- Surface Type (Last Chance) elements have a single layer stainless steel mesh supported by perforated sheet tube.
