Valtek Valves

The Valtek Sizing & Selection Manual is a comprehensive, easy-to-follow reference guide for determining the proper control valve for a particular application. The material follows the sequential order of the typical Valtek Valves quote sheet.

This introduction discusses general information about control valve sizing. It also outlines the basic control valve parameters which must be known for correct sizing.

THE VALTEK CONTROL VALVE

A Valtek Valve is a final control element used in instrumentation systems to regulate the flow, pressure or temperature of liquids and gases in process systems.

A control valve is different from other valves in that it has a power positioning actuator for moving the closure mechanism in response to an external signal. The actuator’s energy source is usually provided from an independent source.
