Here you will find all the technical details to select the proper hydraulic flow control valve for your application.
Technical Union Flow Control Valve Catalog.
Hydraulic calculation for cylinder speed
This is how you calculate the speed of a hydraulic cylinder.
Using the proper Fluid Power hydraulic formula you can calculate the speed of the cylinder in feet per minutes.
Hydraulic symbols for pressure valves
Learn how to properly draw the different types of symbols for hydraulic pressure valves such as relief valve, unloading valve, pressure reducing valve, counter balance valve, and sequence valve.
Hydraulic Symbols for pumps
Here you will learn about how to properly draw the hydraulic (Fluid Power) symbols for hydraulic pumps, including features such as rotation, direction, variable pumps, etc.
Hydraulic symbols for directional control valves
These are some of the hydraulic symbols / hydraulic schematics for directional control valves.
Explanation on how to draw 3 position and 2 position hydraulic valves along with different centers, controls, and centering mechanisms.
Válvula de alivio ventilada
La manera más fácil de trabajar con un sistema hidráulico de bomba de caudal fijo es ultizando una válvula de presión ventilada para poder ahorrar caballos de fuerza durante los momentos de stand by de la bomba hidráulica.
Vented Relief Valve
A vented relief valve is used to unload the pump flow through the relief valve at very minimum pressure setting to avoid over heating your hydraulic system.
Hydraulic Pump Interchanges
This is the best way to learn how you can interchange any hydraulic pump you have for a better alternative.
Often people need to interchange their hydraulic pumps from existing system to a different pump that can offer better delivery time, pricing, or simply because their old pump hard to find or obsolete.
Hydraulic Horsepower
Hydraulic horsepower formula / equation to calculate the max HP required for your hydraulic system.
Check Valves
These are different examples of system applications for hydraulic check valves. Check valves are a very important component for proper work of hydraulic equipment as shown in these examples.
