What is a Spool Valve? – Types, Configurations, Applications

These valves have a cylindrical shaft called a spool which slides into a machined bore in the directional control valve housing.

In this post, we will understand the types of DC injection braking and their uses in a VFD (variable frequency drive).

In this post, we will understand the difference between the stepper motor and servo motor and compare them.

Learn the falling positive and negative edges instructions in the statement list (STL) language in PLC programming.

In this post, we will see the various causes which change the PLC operation to stop mode and its common reasons.

This article covers multiple position calibration procedure of temperature ovens. Also called as Mapping of Temperature Chamber.

This article covers single position calibration of temperature sources. Here the unit under test (UUC) is the temperature bath.

In a level control with horizontal float consists of the main valve, needle valve, pilot float, and float with an arm.

Learn the calibration of the temperature sensor with an Indicator with a temperature bath, master sensor, and multi-function calibrator.

We are going to explain how to use SET, RESET and ASSIGN instructions with STL programming in a PLC.
