Single Seated Single seated valves are one form of globe valve that are very common and quite simple in design. These valves have few internal parts. They are also smaller than double seated valves and provide good shut off capability. Maintenance is…
Introduction Sound is generated from the movement of fluid through a valve. It is only when the sound in undesirable that it is termed ‘noise’. If the noise exceeds certain levels then it can become dangerous to personnel. Noise is also a…
What is a control valve? Control valve is a power operated device which modifies the fluid flow rate in a process control system; consists of a valve connected to an actuator mechanism that is capable of changing the position of a flow…
What is a control valve? A control valve is a final control element used to regulate the flow of liquid through a channel. They can throttle flow over a range of fully open to fully closed. A control valve is installed perpendicular to…
Plug valve is a rotary control valve which is used to control flow. Plug valves are simple and often economical. The plug valve is much similar to the globe valve. Construction and working: The simplest form of a plug valve is…
Introduction The motor operated valves (MOV) is an important element of the plant and pipe system. These valves are generally large and are used for different applications such as pump discharge, etc. The control valves operated by motor are often called on…
A pinch valve is a simplest valve design. It is a linear motion valve that is used to start, regulate and stop fluid flow. It uses a rubber tube (pinch tube) to control the fluid. Pinch valves are ideally suited for the handling of slurries,…
Impulse Piping Installation Precautions The impulse piping that connects the process outputs to the transmitter must convey the process pressure accurately. If, for example, gas collects in a liquid filled impulse piping, or the drain of a gas-filled impulse piping becomes plugged,…
Introduction There are two ways to mount a 3-way manifold valve mounting techniques: 1] The pipe mounting type 2] The direct-mounting type in this session we are going to discuss about Manifold valve mounting techniques Pipe-Mounting Type 3-Valve Manifold 1) Screw nipples into the connection…
Introduction A ball valve is a rotational motion valve .The ball consists of a ball shaped disk .this ball shape disk rotates to stop or start flow. The ball has a hole, or port, through the middle so that when the port…
