In a control loop, these valves act as the correcting element. There are hand-operatedcontrol valves, but typically they work automatically. Examples include ball and plug valves, needle valves, butterfly valves, and check valves to name a few. 1. Needle Valve When you have tiny piping with...
This type of valve gives you excellent control of liquid flow through the valve and a secure shutoff when closed. They are often used in sewage treatment, chemical, and paper plants. 2. Check Valves These types of valves prevent the reversal of fluid flow in piping. Check valves remain ope...
6. Adapters: These are versatile fittings that allow connections between different types of pipes or between pipes and valves or fixtures. Adapters are frequently used in the transition from metal to plastic pipes or when converting between threaded and solvent weld connections. When selecting pipe f...

A comprehensive introduction to valves. Everything you need to know from valve types and standards to materials and uses.
There are of three types – throttling, isolation, and non-return. The isolation valves are used to disconnect a part of the piping system temporarily for maintenance or repair. The throttling valves are used to regulate the amount of pressure of a liquid in a pipe; they can also withstand...

PVC valves are crucially important when talking about all different kinds of piping systems because they control the amount and rate of flow of liquid. They have many different applications and uses, with some of the most popular including plumbing, constructing our-door shades, helping build green...
Is there a general rule as to when we would use a gate valve as opposed to a butterfly/wafer valve, and same for globe/ball valves and diaphram valves? I appreciate that the material of any type will change depending on the product passing through but are there general guidelines or ...
There are three major types of air valves as classified by the American Water Works Association, but all are sometimes incorrectly called "air-release valves". The three types of air valves are: air-release valve, air/vacuum valve and combination air valve. 1. Air/vacuum valve/large-orifice...
