GVO 4397673 Excavator Parts E70B E307 Hydraulic Gear Pump A10V43 Pilot Pump Piston Pump Tail Pump

Product Description

The hydraulic pump pilot pump of the GVO brand for the main pump of the Hitachi EX70 EX60 excavators is suitable for various types of hydraulic components.
High-quality pilot pump, directly sold by the manufacturer without any middlemen profiting from the price difference. Adequate inventory ensures prompt delivery, and the after-sales service is reliable.

Product Description

This overflow valve is designed for the E70B and E307 models and is a crucial pressure safety component in the main control distribution valve of the excavator. It fully controls the maximum working pressure of the entire hydraulic circuit and builds a reliable pressure protection barrier for the entire hydraulic pump, tubing, cylinder, and multi-way control valve assembly.

The valve body is made of high-strength cast aluminum alloy base material combined with a precision quenched valve core component. It strictly conforms to the structural dimensions of the accessory, and the flange installation holes, internal sealing grooves, and drive shaft structure are fully compatible with the installation positions of the E70B and E307 distribution valves. After purchase, it can be directly installed in place without the need for grinding and modifying the valve seat or adjusting the pipeline interface, significantly saving the time for accessory replacement.

The raw materials of the valve body have undergone anti-pressure and impact quenching treatment, and the valve core has been finely ground. Combined with high-temperature resistant and wear-resistant sealing gaskets, it can withstand the long-term high-temperature hydraulic oil flushing in the construction site and resist valve core wear caused by sand and impurities. In hot summer construction sites and muddy and harsh working environments, it can still maintain the valve core opening and closing sensitivity, and is less likely to encounter common problems such as valve core jamming and oil leakage and pressure relief. It is suitable for the long-term, uninterrupted, and high-intensity operation requirements of the excavator.
