Product Description

K20030068 Excavator joystick pilot valve assembly for SY55


Product Introduction

K20030068 Excavator joystick pilot valve assembly for SY55A pilot valve is a small valve that controls a limited-flow control feed to a separate piloted valve. Typically, this separate valve controls a high pressure or high flow feed. Pilot valves are useful because they allow a small and easily operated feed to control a much higher pressure or higher flow feed, which would otherwise require a much larger force to operate; indeed, this is even useful when a solenoid is used to operate the valve.
