4T-9406: Pilot Check Valve

Description: A pilot check valve allows fluid to flow in one direction while preventing flow in the opposite direction unless a certain pressure threshold is met. It consists of a main valve body and a pilot valve. The pilot valve is connected to a control pressure line, which regulates the opening and closing of the main valve. Attributes: • Durable and can withstand high pressures, temperatures, and corrosive fluids or gases. • High flow capacity, which allows it to handle large volumes of fluid. • Easy to install and require minimal space due to their compact design. Applications: A pilot check valve is used in brake systems to prevent the brake fluid from flowing back into the master cylinder when the brake pedal is released. It is extensively used in Cat 613C, 615C, 621, 621E, 621F, 621G, 621H, 621K, 621S, 623, 623E, 623F, 623G, 623H, 623K, 627, 627B, 627E, 627F, 627G, 627H, 627K, 631C, 631E, 631G, 633E, 633G, 637E, 637G, 637H, 639E, 651E, 657E and 657G Wheel Tractor Scrapers, 613C, 621E, 621G, 623E, 623G, 627E, 627G, 631E, 631G, 637E, 637G, 651E, 657E and 657G Scraper, 621G, 631G and 657G TH35 and TH38 Powertrain.
