An example of a normally-closed automatic valve is Plast-O-Matic's Series CKM Check Valve. The valve opens when pressure is present at the inlet (or upstream) side. When that pressure ceases, the diaphragm inside the valve automatically forces it closed. The inlet pressure must overcome the ...
Another common type is the ball valve, in which a ball with a hole through it is rotated within two seals. When the hole is aligned with the inlet and outlet, the valve is open. When the ball is turned, and the solid sides of the ball align with the inlet and outlet, the valve ...
A float valve is a device that is used to control the level of a fluid in a tank by opening and closing a valve in response to...
A valve gear is a component that controls the intake and exhaust of steam in an engine. The mechanism is usually connected a steam engine's valves, and was often used in early locomotives. Such an engine is typically most efficient when the inlet is open for a short time, before it ...
The sprinkler valve has two pipes connected to it: the inlet and the outlet. The inlet pipe brings water from the household supply to the valve. The inlet ends in the middle of the valve with a stopper called a diaphragm, which is held in place with a rod and a spring which are ...
A solenoid valve is an electro magnetically controlled mechanical valve used for the ON/OFF (open/closed) or diverting control of liquid or gas media. Solenoid valves are available with a number of port configurations. The most common solenoid valve is a 2/2 way or 2 port 2 position ...
Inlet Butterfly Valve Function The IBV directs the airflow into the first stage of compression in a straight line. The impeller then spins the air using power from the main driver, increasing air velocity and directing the flow into the diffuser portion of the compressor. When partially throttl...
Pressure relief valve– a valve that releases excess pressure by opening a passage to an area of lower pressure. These valves are often used on heating systems and fire sprinkler systems. In plumbing, a similar type of valve (pressure reducing valve), is used when high inlet pressure from th...
What is a Process Flow Diagram? A Process Flow Diagram (PFD) is a simplified diagram that shows the process flow of a manufacturing process in proper sequence. This diagram should consist of every essential detail like main equipment, Heat, Material, & Energy Balance, tag number, chemical ...
A check valve, a non-return or one-way valve, is a mechanical device that allows a gas or liquid to flow freely in one direction while preventing reverse flow in the opposite direction. The direction in which the fluid or gas can flow is called the free flow direction; the direction in...
