Control Valves used in the hydraulic system

Introduction to control valves In a general layout of the hydraulic system, after the pump, the next important components are present which are control valves. They are generally placed in between the pump and actuators. The pump generates a flow of oil which is fed to the actuators through a controlling element known as a valve. Basically, the valve is nothing but a device that controls the oil energy.   Need for control valves 1.      For blocking/stopping of flow of oil. 2.      To control the direction of flow. 3.      To control the pressure of oil. 4.      To control the flow quantity. 5.      Other special functions such as controlling the oil flow in one direction, diverting the flow, etc. Classification of control valves 1.     According to construction a)     Seat valves: The seat valve consists of a poppet that sits on a sp...

  What are Threads?  Grooves of equal measurement or shapes made on a round cylindrical article or pipe are known as threads. In other words, threads of equal pitch and equal depth made on the parallel round cylindrical surface or conical round surface are called threads. A thread is considered as a raised form known as a helix. Or A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the straight threads and later known as tapered threads. The thread can be external on a bolt or internal inside a nut. threads are an important part of the screw as a simple machine and also as a fastener. Types of Threads 1.      RightHand Threads These threads are tilted towards the right-hand side. These are fastened in a clockwise movement. These are known as right-hand threads. 2.      Left-Hand Threads These threads are tilted towards the left hand. Left-hand threads are tightened in an anticlockwise direct...
