There are four basic types of Flow Valves. These include Needle valves, Diaphragm valves, Ball valves, and Pneumatically actuated globe valves. Which one is right for your needs? This article will explain each type. You can also use these products to automate some processes. These valves are great for many different industries, including pharmaceutical, chemical, and food and beverage production. Listed below are some of the most common types.
Needle valves are a type of pressure control device that regulates flow rate in piping systems. A needle valve’s design allows it to accurately control the flow rate of the fluid being controlled. The seat and the needle fit together in the channel. The stem is made of stainless steel, which gives it a high degree of precision in regulating the flow rate. This type of valve offers a high degree of precision in controlling flow, although its restricted flow can be a disadvantage.
A diaphragm valve is an excellent choice for low-pressure, corrosive liquid applications. Its diaphragm is made of highly elastic polymeric material that moves to the bottom of the valve body and limits the fluid flow. When the valve is fully open, the diaphragm lifts. As a result, the fluid flows beneath it. There are many advantages to diaphragm valves, including corrosion resistance to lubricants. A diaphragm valve’s flow coefficient and pressure drop are important considerations when purchasing a flow valve.
Flow valve manufacturers offer a variety of ball valves for various applications. Some of these valves can withstand highly corrosive fluids and cryogens. Whether a ball valve is used manually or mechanically, its design must meet the highest safety and environmental standards. For this reason, ball valves feature corrosion-resistant materials, fire-safe testing, blowout-proof stems, and tight shutoff features.
Pneumatically-actuated globe valves
A common application of pneumatically-actuated globe valves is in fuel oil and cooling water systems. They are also commonly used in feedwater and chemical systems. Boilers, turbines, and cooling water systems are other examples of industries where globe valves are used. These valves secure pressure up to 50 bar and operate in a wide temperature range. Here is a closer look at their different types.
Hemostatic flow control valves
The market for hemostasis flow control valves has seen a steady growth over the past few years, thanks to several industry players consolidating their position, expanding their product portfolios, and strengthening their customer base. For example, in May, Argon Medical acquired Mana-Tech, Ltd. and intends to expand its presence across Ireland, the U.K., and Europe. In the coming years, many other hemostasis valves manufacturers will join the race.
