New 5R55W 5R55S 5R55N Sonnax Pump Flow Control Valve Assembly
Includes:
1 Pump Flow Control Valve Assembly
1 O-Ring
Description:
The OEM flow control valve is designed to increase pump efficiency by rerouting excess line pressure back to the suction side of the pump. It is common for the plunger valve to become stuck open, or for the canister to wear. This decreases line pressures and results in delayed engagements. The Sonnax pump flow control valve assembly eliminates the sticking and wear problems with redesigned and precisely machined parts.
Harder canister material resists wear and has improved valve support to prevent sticking
Plunger valve is made from case-hardened steel and has annular grooves to prevent side loading
Larger o-ring eliminates pressure loss at the pump face
Canister restores the regulated line orifice to improve valve and hydraulic stability
Drop-in-place replacement assembly for easy installation
