6J-0428: 53.87mm Outer Diameter Pilot Seat

Description : A Relief Valve Pilot Seat is a component of a relief valve assembly. It controls fluid or gas flow and ensures the relief valve's proper functioning. It acts as a sealing element that prevents the passage of fluid or gas until a specific pressure threshold is reached. When the system pressure exceeds the predetermined set point, the pilot seat opens, allowing the fluid or gas to flow through the relief valve, relieving the excess pressure. Attributes : • Made of durable and corrosion-resistant materials. • Designed to withstand high pressures without leaking or deforming. • Has Case Hardening 0.5-0.8. • Has Rockwell hardness of 30 N 68-73. Applications : A Relief Valve Pilot Seat provides a sealing function and controls fluid or gas flow through the relief valve based on the system pressure. It is widely used in Cat 613C, 615C, 621E, 621F, 621G, 621H, 621S, 623E, 623F, 623G, 623H, 627B, 627E, 627F, 627G, 627H, 631C, 631D, 631E, 631G, 633D, 633E, 633G, 637D, 637E, 637G, 637H, 639D, 639E, 641B, 651B, 651E, 657B, 657E, and 657G Wheel Tractor Scrapers, 613C, 621E, 621G, 623E, 623G, 627E, 627G, 631E, 631G, 637E, 637G, 641, 641B, 651, 651B, 651E, 657, 657B, 657E, and 657G Scraper, 621G, 631G, and 657G Oem Applications, 786 Bottom Dump Body, 786, 793, 793B, AD40, AD45, AD45B, AD55, AD55B, and AE40 Truck, 834B Wheel Type Tractor, 836 Compactor, 988, 988B, 988F, 988G, 992, 992B, 992C, 992D, 994, 994D, 994F, 994G, 994H, R1700G, R2900, R2900G, and R3000H Wheel Loader, AD60 and AD63 Articulated Truck, TH35 and TH38 Powertrain.
