Directional Control Valves (Hydraulic & Pneumatic): Types, Mechanism, Actuating Method, Applications

✅ Join us here, get awesome perks, and support us, all at once:    / upmation   In this video, we're going to answer the following questions: Is there a difference between a Spool Valve and a Directional Control Valve? What is a Directional Control Valve? We will also talk about: Directional Control Valve Types such as Sliding Valves and Poppet Valves Hydraulic valve types Pneumatic valve types Directional Control Valve actuation methods and symbols As the first step, we can classify the valves from their ‘Function’ aspect or in other words, the task they perform. Our functional classification includes: Non-return valves like check valves Flow control valves Pressure valves like pressure regulating valves Directional control valves like spool valves In both Pneumatic and Hydraulic systems, valves are fallen into the same categories. But despite the same functional categories, it does not mean that a Hydraulic directional control valve and a Pneumatic directional control valve of the same types are interchangeable. That is due to the different characteristics of different control media in Pneumatic and Hydraulic systems. Different characteristics of compressed air and hydraulic fluid will affect the size, operating pressure of the valve, and lots of other elements. Next, we will focus on Directional Control Valves and classify them from the design aspect. 👉 Watch: 5/2-way Solenoid Valve Explained ▶ https://upmation.com/directional-cont... I’ll consider two subcategories for Directional Control Valves: The first one is the Poppet Valves The second is the Slide Valves Poppet valves have different types depending on the type of closing element that has been used in them. Slide valves have also three different types: Spool Valves (Sliding Spool Valves and Rotary Spool Valves) Longitudinal Flat Slide Valves (Slide Gate Valves) Plate Slide Valve or Rotary Plate Valve Be aware to don’t confuse a rotary plate valve with a rotary spool valve. In the rotary spool valves, the holes in the spool and the ports on the housing will circumferentially match. But in Plate Slide Valves, the ports, and the holes match with each other axially. There are various actuation methods to switch the position of a Directional Control Valve: Manual actuation of the valve (normal lever, detent lever, pushbutton, etc.) Mechanical actuation of the valve (manual override, roller operated valve, spring return, etc.) Electrical actuation of the valve (solenoid valves) Hydraulic actuation -Pneumatic actuation Pilot actuation or indirect actuation of the valve (pilot operated directional control valves or two-stage valves) Hybrid actuation =========================== ✅ Please SUBSCRIBE to get notified about the new videos: https://bit.ly/32mlhu9 =========================== Timestamps of this video: 00:00 Valves Categories (Valve Function, Valve Design, Actuation Methods) 01:00 Pneumatic Valve Types and Hydraulic Valve Types 02:02 Directional Control Valve Types 02:48 Poppet Valves (as a Directional Control Valve) 03:17 Slide Valves (as a Directional Control Valve) 03:29 Spool Valves (Sliding Spool Valve & Rotary Spool Valve) 04:32 Longitudinal Flat Slide Valve (Slide Gate Valve) 05:14 Rotary Plate Valve 06:05 Hydraulic & Pneumatic Valves Classification 06:40 Directional Control Valve Actuator Types 08:15 Solenoid Valves (Solenoid Actuated Directional Control Valve) 09:16 Pilot Operated Valve 10:08 Directional Control Valve Symbols (Actuation) =========================== ▶ If you've missed our most recent videos, watch them here: Electrical Panel Enclosure Part 2 (Baying Systems, Panel Compartments, etc)    • Electrical Panel Enclosure | Baying S...   Electrical Panel Enclosure Part 1 (Enclosure IP rating, Gland Plates, etc.)    • Electrical Panel Enclosure Explained ...   How Electrical Control Panel Works    • How Electrical Control Panel Works | ...   =========================== ▶ If you want to become a confident PLC programmer, don't miss this free "Siemens PLC Training" course (This course will be continued): Part 1: Up & Running with PLC Ladder Programming https://upmation.com/plc-hardware-con...
