Apart from great industrial valve manufacurers in China, there has been exponential growth in the market for industrial valves made in the United States recently. Industries such as petroleum, chemical, and water and wastewater command much of the market. In 2018, there was a 1.45% growth in valve sales and shipments in the US market alone. This is a good sign for valve buyers!
This article introduces the top industrial valve manufacturers in America and the products they offer.
Industrial ball valves are devices that isolate or control the flow of media in any given industrial application. Industrial ball valves are quick to open because one only needs to turn the handles by 90 degrees. Ball valves have spherical discs that allow or prevent the flow of media through the valves.
There are many ways to classify ball valves. One of them is by the size of the opening of the disc with regards to the size of the pipe diameter. A ball valve can be a full port or full bore or it can be a standard port or bore. Another way to classify these valves is according to the design of the ball discs. It can either be a floating ball valve design or a trunnion-mounted ball valve design.
Emerson is an automation solution provider and a reputable industrial valves manufacturer with a very extensive line of valves. Recently, Newsweek and Statista ranked Emerson as one of America’s most responsible companies. Emerson has garnered certificates such as CE marking, CRN, PED, Lloyds’ Register, NACE, CUTR, ATEX, SIL, ABS, 3A, CSA, IECEx.
Its ball valves have diameters ranging from DN 25 up to DN 400. Emerson services chemical, oil & gas, water, food and beverage, pulp and paper, and wastewater applications. Emerson control valves can handle extremely low temperatures, less than -40F. These valves can be made of carbon steel, stainless steel, alloy, duplex, 316 stainless steel, and 304 stainless steel.
Not only is Emerson a valve manufacturer, but it is also one of the top industrial valve suppliers. It carries the brands KTM, Virgo, Neotecha, Fisher, Vanessa, Keystone, Tartarini, Clarkson and Yarway.
Gate valves are shut-off valves that work to restrict the flow of fluid through any system. The valve features a disc shaped like a gate that opens and closes to help start and stop the flow of fluid. Gate valves have a simple construction and are used with larger pipe diameters. Gate valves can have a rising or non-rising stem and can be customized to handle high-pressure applications.
Gate valves are usually made of cast iron, ductile iron, stainless steel, cast carbon steel, gunmetal, alloy steels, and forged steels.
Flowserve started out as pump provider and as the company grew, it stretched out to other industries until it became one of the top gate valve manufacturers in the USA. Today, Flowserve valve product line ranges from ball valves, butterfly valves, rotary control valves, linear control valves, server service control valves, gate valves, globe valves, check valves and plug valves. Flowserve is a certified ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007 company.
There are seven products under its gate valve product line, namely, flexible split wedge gate valves that are specialized for feedwater and steam isolation purposes, flexible wedge gate valves, the slab gate valves and the split wedge gate valves. The product line has varied sizes ranging vary from NPS 4 to 42 and with pressure class up to Class 2500. The seating materials include metal and carbon steel.
Solenoid valves are electromagnetically driven industrial valves that feature a solenoid or an electric coil with a plunger at its center. The electric current creates an electromagnetic field that acts on the plunger.
This plunger is being pulled towards the center so the orifice opens, allowing the passage of the media. Solenoid valves are often used in liquid and gas applications such as heating systems, compressed air technology, and irrigation systems.
Parker Hannifin is a Fortune 250 world leader that started as Parker Appliance. With a legacy of innovation, Parker Hannifin is now one of the top companies in the US that focuses on specialty industrial machinery, including solenoid valves.
It is in the Diversified Industrial where you can find industrial valves, static and dynamic sealing devices and fluid control solutions. The company manufactures original equipment and replacement components that are suited for packaging, processing, transportation and the likes.
The Parker Hannifin valve line consists of solenoid operated directional control valves, pneumatic solenoid valves, in-line flow control valves, check valves with thermal relief, and others. The solenoid valve product line includes valves having 2 or three position configurations, pneumatic actuation and a high-density manifold that can have 32 addressable solenoids. Pneumatic zoning allows multiple pressure zones in one manifold so the valves can work with different pressures.
Automatic control valves is a flow control valve that regulates the flow of media. Such valves respond to changes in temperature or pressure, often directed by flow meters or pressure and temperature gauges.
Automatic control valves do not need an external power source. These rely on internal pressure for the opening and closing of the valve.
Bi-Torg Valve Automation is a subsidiary of Strahman Valves, Inc. The company manufactures automatic valves and has an extensive line of industrial valves such as ball valves, butterfly valves, and the likes.
The Bi-Torg automated valve line includes stainless steel valves in NPT with either socket weld or flanged end connections. The valve size in this category can range from 1/2inches to 6 inches. These have pressure ratings ranging from Class 300 to Class 600. The brass valves have NPT connections with valve size ranging from 1/4inch to 4 inches. PVC and CPVC automatic valves have ½ inch through 4 inches, also with NPT or socket weld. It comes with a pressure class ANSI Class 150 rating.
Check valves are used in industrial applications where a unidirectional flow of media is required and a backflow should be prevented.
As self-automated valves, check valves are still functional even when the pipeline loses electricity or humans to manually open or close the valves. Check valves are media flow reliant. This means that when the flow decreases, the check valve would begin to close and vice versa.
Curtiss-Wright is a manufacturer of highly advanced equipment used for defense, aerospace, power generation, and general industrial markets. Founded by the Wright Brothers and Glenn Curtiss, the father of naval aviation, Curtiss-Wright offers its services in critical applications and high-performance industrial valve markets.
The company’s critical process valves include ball valves, triple offset, resilient and specialty valves, cryogenic, pressure reduction, and Zen-trol check valves, by-pass control valves, discharge control valves, injection and isolation control valves, and the likes.
Curtiss-Wright check valves comes in product brands like Phonix, Valve Group-Korea and Strack. These valves can fall under the standard control check valve, Zen-trol Control Valve or the Cryogenic Service Control Valve. These valves can be of three configurations: straight body, Y-pattern or Angle pattern. Depending on their use, check valves can be utilized for aggressive, non-toxic gases or liquids or cryogenic applications. Curtiss-Wright check valves can withstand pressure ratings of Class 900. These can be made from different grades and types of steel, including Hastelloy, high-temperature chromium steel or carbon steel.
