Cartridge Valves by Joji Parambath

About the Book

With the introduction of cartridge valves in the 1950s, an essential innovative approach to the design of hydraulic valves began. The basic cartridge valve consists of an insert assembly that slips into a cavity machined into a manifold. Initially, the cartridge valve was intended to perform a single function; therefore, a cavity was designed to encompass the valve. Later, the cartridge valve technology grew to include multifunction and integrated circuit features with many cartridge valves incorporated in a single manifold block. In recent years, cartridge valve technology has seen many improvements to reduce leakage and its complexity and size, and increase its reliability, efficiency, and cost-effectiveness.

This book provides an in-depth understanding of multi-function cartridge valves, including their concepts, configurations, and circuits for check, directional, flow, and pressure control functions. It also covers the active logic valves and proportional cartridge valves, as well as the constructional features of integrated manifolds. Additionally, it offers detailed information on cartridge valves’ characteristics, specifications, advantages, applications, and maintenance. The book is organized in an easy-to-understand manner, with many circuits given in multiple positions for quick comprehension. It is a great resource for anyone learning more about cartridge valves.
