Rotary plow valve for two cylinders VRAP80/100 threads: 3/8" max pressure: 230bar

The FZ Hydraulics VRAP 80/100 plough turnover valve is an automatic sequence and check valve engineered for reversible ploughs equipped with two hydraulic cylinders (such as main rollover and frame alignment/furrow width adjustment).

The valve automatically sequences and diverts oil flow between cylinders once the inversion threshold pressure is reached, allowing the operator to complete the full rollover procedure using only a single tractor spool valve. The integrated pilot-operated check valve locks fluid in place when resting, eliminating frame drift during road transport and active ploughing.

Specification and technical parameters:

• Brand: FZ Hydraulics.

• Component type: Automatic sequence plough turnover valve (for 2 cylinders).

• Model: VRAP 80/100.

• Cylinder bore compatibility: Recommended for cylinder bore sizes 80 mm to 100 mm.

• Port connections: 3/8" BSP female threads.

• Maximum operating pressure: 230 bar (23 MPa).

• Switching pressure: Adjustable via setting screw (factory preset approx. 140–180 bar).

• Body material: Zinc-plated high-strength forged steel housing.

• Application: Reversible multi-furrow ploughs including Kverneland, Lemken, Kuhn, Overum, Akpil, Unia, Pöttinger, Vogel&Noot.

The heavy-duty galvanized steel block provides long-term corrosion resistance, mechanical durability, and reliable protection against field contaminants. Hardened internal valve seats and precision-ground spools deliver tight fluid retention without internal leakage, ensuring smooth rollover cycles under high continuous loads.
