Description
Safety proportional solenoid valve for Caterpillar
Looking for a safety proportional solenoid valve for Caterpillar? This is an aftermarket replacement built to the original equipment drawing — same mounting interface, same fitment geometry, no rework required at installation.
Part number / cross reference
OEM and interchange reference: E307.1
Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us — we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.
Why this part fails — and what we do differently
On a hydraulic safety proportional solenoid valve the clearance between mating parts is measured in microns, so ‘close enough’ is not close enough. We machine and assemble to OEM specification, pressure-test each unit and record the values. Send the machine serial number and we confirm the exact variant for Caterpillar machines in writing before you pay.
Ordering, packing and warranty
We ship single units worldwide and consolidate full containers for distributors. Every safety proportional solenoid valve is individually boxed and labelled with its part number, and pre-shipment photos and dimensional checks are provided as standard. Warranty against manufacturing defect: 6–12 months depending on the part category.
