Webinar: Control Valve Sizing and Design

Webinar: Control Valve Sizing and Design
  • Date From 4th March 2022
  • Date To 4th March 2022
  • Price Free of charge, open to all.
  • Location Online: 09:00 GMT. Duration: 1 hour.


This webinar is about control valve calculation and optimisation for both sizing and design.

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. In automatic control terminology, a control valve is termed a "final control element".

Andreas will talk about control valve calculation and optimisation for both sizing and design, especially from the control engineer point of view. This will be demonstrated using F.I.R.S.T.’s CONVAL® software which includes engineering calculations for various components and procedures in the process industry. Practices used include DIN, VDI, VDMA EN/ISO standards or ISA, ASME, API, etc and the use of a relevant database of device manufacturers’ data and physical properties plus thermodynamics. Other relevant calculations for future discussions include for other types of valves, throttle devices, thermometer protection tubes / thermowells, piping calculations to heat exchangers or pumps, etc.

This webinar is aimed at instrumentation and control plus control and automation engineers.


Andreas Vogt, Managing Director, F.I.R.S.T. GmbH

Andreas is the Managing Director at companies in F.I.R.S.T. group. His goal is to continuously improve CONVAL®, a computer software product that was developed to provide a toolkit of engineering calculations for the process industries. Andreas also does engineering consulting and customised software development for technical applications and is widely published in the process industries in the area of process valves and other related engineering calculation areas. Andreas is trained in software solution development for engineering, instrumentation and process design along with business process management in engineering.
