The main valve body is made of vermicular graphite cast iron material, which has better shock absorption and thermal conduc-tivity. Small shrinkage tendency to avoid spool jamming.

Withstood 3 million cycles of ultra-high pressure endurance testing without cracking, ensur-ing reliable quality.

· Standard equipment includes a 1.2 cubic meter earthmover bucket.

·    The large-capacity earthmoving bucket is specialized and optimized for less cutting resistance and a 25% increase in wear resistance.

· Key areas are made of high-strength plates and wear-resistant plates, with bucket teeth and seats made of wear-resistant materials to extend service life.
