GRH gear pump and valves are successfully used in YTO tractor for a few years.


YTO is the largest agricultural manufacture in China, which has been using an European brand valves and Gear Pump. YTO has a requirement for the internal leakage of the valve, to hold the pressure within a fixed period. During the static descending test, the rear attachment on the tractor is allowed to descend 30mm within 30 minutes.

After discussion with YTO, we design our valves and made our test bench, and we make our valves.

test results of GRH valve is 8mm.

After we sent the valves to YTO for their shop test and field test, we are told that the operating torque of GRH handles is lighter.

Gbv200 129 93pf

GRH drop pressure is 15%, much less than the previous valve 35%.

With these features, YTO replaces the European brand valves with GRH valves very soon. And GRH has been authorized by YTO the best supplier of valves and pumps for 5 constant years.

Meanwhile YTO also change the Lifting Pump and Steering Pump from that European brand to GRH.
