The spool body adopts high-precision grinding process matched with precise valve head assembly, ensuring stable pilot pressure regulation. It effectively fixes common problems such as low pilot pressure, heavy control levers, slow action response and pressure fluctuation, and maintains constant pressure of pilot control system.
Made of high-hardness wear-resistant alloy steel with surface strengthening treatment, resistant to hydraulic oil erosion and abrasion under long-term frequent reciprocating movement. Dimensions strictly follow OEM standards with precise clearance to reduce pilot internal leakage. Direct replacement fits pilot regulator assembly on Hitachi EX-5 and ZX-3 series main control valve.
