The characteristic feature of self-operated temperature regulators is their compact design, including a sensor, a valve and a capillary tube. Their simple operating principle is based on fundamental mechanical, physical and thermodynamic laws. A temperature control loop with a heat
Positioners, converters, limit switches, position transmitters, so- lenoid valves and lock-up valves are transfer elements designed to adapt pneumatic control valves to the requirements of indus- trial plants. Supply pressure regulators and air reducing stations are used to supply the
This document is focused on design aspects for control valves in petrochemical plants. A must read doc for any instrumentation engineer! With three decades of experience in demanding applications, Mr Siemers has a deep appreciation of developments and trends in
In this how-to video, we’ll assemble a 2″ SAMSON 3241 globe valve and prepare for actuator mounting.
Cavitation has been a familiar phenomenon for a long time particularly in shipping. In 1917, the British physicist Lord Rayleigh was asked to investi- gate what caused fast-rotating ship propellers to erode so quickly. He discov- ered that the effect
These application notes provide a simplified procedure for sizing control valves at standard service conditions. The data required to size a valve, such as the nominal size, nominal pressures and KVS, is contained in the SAMSON data sheets for self-operated
