These Tilton flow control valves work by restricting the return flow of the hydraulic fluid by a tunable amount, reducing shock loads to the driveline by allowing the clutch to slip slightly during engagement. They do not restrict flow during release. The shock load is a result of an abrupt clutch engagement when the crankshaft and input shaft speeds are not precisely matched. The Tilton Flow control valves are designed to reduce the risk of traction loss when downshifting and reduce the chance of damaging driveline components.

Aeromotive high-flow one-way check valves are designed to prevent back-flow with minimal pressure drop. AN O-ring male inlet/female outlet connections allow easy installation into a fuel pump outlet port without adding additional lines, hose ends, or fittings. They're ideal for use when preventing drainback after the fuel pump is turned off, or when dual pumps are employed and both pumps will not always be running together. CNC-machined from 6061-T651 billet aluminum alloy with a Type II bright dip anodized finish, the fuel check valves are available in multiple sizes.

Improved Racing high-flow flapper check valves are ideal for use in oiling systems (wet sump and dry sump), fuel systems, crankcase pressure ventilation systems, and more. Most check valve designs—including poppet check valves, ball check valves, diaphragm check valves, piston check valves, and others—are restrictive, resulting in a pressure drop across the valve even when fully open. Improved Racing's check valves use a flapper design, originally developed for military jet engine turbines, that swings completely out of the fluid's flow path, adding virtually no flow restriction. These check valves were further optimized for low restriction at high flow rates using flow simulation software—and were designed to exceed most military specification requirements. The valves have been tested at up to 1,000 psi of backflow holding pressure without catastrophic failures or excessive leakage. This allows Improved Racing to very safely rate these valves to hold 300 psi of backflow pressure under normal operating conditions with a very high factor of safety. For comparison, the military surplus flapper check valves tested failed catastrophically with complete pressure loss at less than 200 psi. This flapper-style valve has a very low cracking pressure of less than 0.05 psi. Every internal component (hinge, spring, hinge pin, and gasket core) is made from stainless steel to ensure long-lasting, reliable performance and compatibility with just about any fluid, including corrosive fluids. The check valve's gasket is made from FKM (Viton®) rubber bonded to a stainless steel core, giving it a high operating temperature of up to 302 degrees F. It's also highly chemical-resistant and compatible with all types of fuel. Improved Racing's check valves are available in multiple fitting sizes, and the inlet and outlet halves can be mixed and matched to create a completely custom valve. Features and specifications: * Flapper design allows for very high flow with low restriction * Design optimized using flow simulation software * FKM (Viton®) rubber seal * All stainless steel internal components for compatibility with a wide range of fluids * 6061-T6 billet aluminum body with black MIL-A-8625 Type II anodized finish * Laser marked with flow direction and hinge location per military specification * Maximum operating backflow holding pressure of 300 psi, burst backflow holding pressure of over 1,000 psi * Maximum unchecked (normal direction of flow) operating pressure of over 1,000 psi * -40 to 302 degrees F operating temperature rang * Lifetime Warranty
