Anything about industrial valves

Control valves have many applications in the industry. This article intends to thoroughly review the types of expansion valves, control valves, and ball valves. Join us.

An expansion valve is a device in steam engine valve gear that improves engine efficiency. It operates by closing off the supply of steam early, before the piston has travelled through its full stroke. This cut-off allows the steam to then expand within the cylinder. This expanding steam is still sufficient to drive the piston, even though its pressure decreases as it expands. As less steam is supplied in the shorter time for which the valve is open, use of the expansion valve reduces the steam consumed and thus the fuel required.The engine may deliver two-thirds of the work, for only one-third of the steam.

types of expansion devices as follows:

Thermal expansion valves

Manual valves

Capillary tubes

Automatic valves

Electronic expansion valves

Float valves

Thermal Expansion Valves

 A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a device that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the vapor leaving the evaporator. read more

 

 

Control valve:

The control valve is an industrial valve that controls the fluid flow, and by controlling the fluid flow, the tank temperature pressure in the process can be controlled. There are different types of control valve, which can be referred to as Globe Valve. To read more about the control valve types, refer to this link.

In the following, we intend to introduce and thoroughly review the control valve parts.

Depending on the control valve characteristics and its design, some parts differ within the control valve, but the rest is pretty much the same. Some parts of the control valve are: Control valve positioner, trim, body, etc.  Click to read more

Different ball valve parts

Let’s get into different ball valve parts to have an overall idea of how ball valve manufacturers put them together to help us control the flow inside a system.

Ball valve :

 ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.The shut position 1/4 turn could be in either CW or CCW direction.

 

Shell or Body
One of the main parts of Ball valve  is its body. The shell or body is used to keep all the units of a ball valve together and help them stay in one place. Plus, it helps keeping all the units safe from outside threats and dangers to some extent. No matter what shape or type the ball valve is, it will always need a shell or a body to keep everything together.  click here fore more information
