Restock Notice: 80704372 Leveling Cylinder Solenoid Valve for 6820 and 8820 Asphalt Pavers
Suzhou Benit Machinery Technology Co., Ltd has added a new supply batch of the 80704372 leveling cylinder solenoid valve to stock. The valve serves the screed leveling circuit of 6820 and 8820 asphalt pavers, and is now listed as a separate item in our Asphalt Paver Spare Parts range so contractors can order it directly by part number.
The Cost of a Slow Leveling Valve
Screed leveling is a closed hydraulic loop: grade sensor, controller, solenoid valve and leveling cylinder. The valve is the fastest wearing element in that loop. As the spool and sealing surfaces wear, internal leakage increases, cylinder response becomes delayed and the screed no longer reacts in time to grade changes. On the mat this appears as thickness variation, waves behind the screed and misaligned longitudinal joints. Operators compensate by making constant manual corrections, which raises labour cost and slows the paving train.
Replacing the valve restores the original response of the leveling circuit. Because 80704372 is a direct replacement, the repair can be done on site with standard tools and the paver returns to the job without modification of the hydraulic block.

What Changed in This Batch
- Part number 80704372 verified – cross reference checked against the original unit before packing, so ordering by part number is reliable.
- 6820 and 8820 fitment confirmed – port layout, connector position and mounting points suit both paver models.
- Leak-tight sealing surfaces – each valve is pressure holding tested to prevent the internal leakage that causes screed drift.
- Stable spool response – precise machining keeps leveling reaction fast and repeatable shift after shift.
- Stock availability – 1000 pieces per month capacity, with stock items shipped in 5–7 days after payment.
Applications
The 80704372 valve is used on 6820 and 8820 pavers in highway surface course work, municipal road resurfacing, parking area construction and industrial yard paving. It is also a sensible spare to hold for rental fleets and contractors running more than one paver, where a failed leveling valve otherwise stops the whole paving train.
How to Order
Send the machine model, serial number and a photo of the old valve. Our team confirms fitment, stock status, price and freight within one working day. Packaging is carton, pallet or wooden box for export, and shipping can be arranged FOB Shanghai, EXW or CIF on request.
