The valve manufacturing industry in the United States is a robust one. There are many valve manufacturers that produce standard and specialized valves suited for any application. But with the sheer number of valve manufacturers scattered around the country, it might be difficult to find that one valve manufacturer that’s perfect for your business.
To help you out, we have curated the top valve manufacturers in the USA for you so you can make an educated buying decision.
The knife gate valve is a type of gate valve designed for viscous media such as slurries. As its name connotes, the knife gate valve has a bladelike disc that can easily cut through thicker media. Such gate valves often have lower pressure drops when opened, and these valves are also lightweight. Knife gate valves should only be used in a completely closed or completely open position since the discs can be easily damaged by media vibration if used in a partially opened or closed position.
FL Smidth is a manufacturer of various industrial components that include valves, apertures, blowers, pumps that are specially made for the cement and mining industries. This company produces bi-directional, high pressure and wafer style knife valves.
FL Smidth knife gate valves come in three KREBS models. The KREBS High-Pressure Knife Gate Slurry Valves have replaceable rubber sleeves that can withstand harsh conditions. On the other hand, the KREBS TG Knife Gate Slurry Valve is a true bi-directional slurry gate valve. The TGW series is suitable for areas with limited spaces. These valves have sizes ranging from 2” to 48” with a working temperature range of -51oC to 149oC, depending on the design. The seat materials can come in gum rubber, high-temperature EPDM, neoprene, nitrile or chlorobutyl.
Bi-Torq is a US-based gate valve manufacturer that specializes in automated and fire safety shutoff valves. This company offers several kinds of industrial valves such as ball valves, butterfly valves, thermal shut-off valves, actuators, and handles.
Bi-Torq knife gate product line comes in standard handwheel but these valves can also be customized to carry pneumatic cylinders or multi-turn electric actuators. The valve size for this gate valve product line ranges from 2” to 48”. The body can be made of stainless steel or cast steel material. The seat options include EPDM, BUNA-N, VITON and TFE materials. These valves can have pressure ratings that range from 30psi to 150 psi. Bi-Torq knife gate valves can be used in pulp & paper industries, mining industries, wastewater treatment, and chemical plants.
High-pressure gate valves are often found in oil production or any system that uses hydraulics. Other applications of high-pressure valves include stem turbine, high-temperature applications, and HRSG. These valves are used to keep pressure within the desired range. High-pressure valves have preset pressure range so as to protect pipeline equipment from damage caused by extreme high pressure caused by the media.
Emerson is a global company that has headquarters in the United States. This company is a leader in automation solutions. Emerson has one of the most comprehensive portfolios in the valve manufacturing industry.
Emerson offers 2 brands of high-pressure gate valves, Fasani and Sempell. Collectively, there are 6 models under the Emerson high-pressure gate valve product line. These valves can range from NPS 2 to NPS 6. Emerson gate valves have metal-to-metal seats with various disc designs. The end connections of these valves can either be butt-weld or flanged. Emerson valves are suitable for liquid, steam, hot water, oxygen, and water applications. These valves carry the ASME B31.1, NACE, India Boiler Registration, PED
Crane is a leading valve provider for the nuclear industry. This company produces several kinds of industrial valves such as gate valves, globe valves, plug valves, among others. Being an OEM, Crane Nuclear carries numerous gate valve designs of well-known gate valve models such as Chapman and Jenkins, among others.
Crane carries two kinds of high-pressure gate valves which are suited for very high differential pressure applications: the pressure seal parallel disc gate valve and the pressure seal wedge gate valve. The pressure ratings for these valves range from ASME Class 600 to Class 2500. The valve sizes can range from 2 ½” to 24”. Crane high-pressure valves have welded-in seat rings for easy maintenance. The parallel disc design is spring-loaded and self-aligning. On the other hand, the wedge disc variant has a fully-guided one-piece wedge disc that is resistant to binding during thermal expansion.
Cryogenic valves are used in extremely cold temperatures, usually starting at -150oC. These valves can handle pressure up to 750 psi. Such valves do not crack or create heat gains when exposed to extremely low temperatures. Cryogenic gate valves often use a wedge type disc that swings to allow or prohibit the passage of the media. Cryogenic gate valves are often used by companies to transfer and transport liquefied natural gas or compressed natural gas.
Parker Hannifin is a global leader in control technologies. This company participates in a wide array of industries including aerospace, oil& gas, industrial manufacturing, industrial & chemical processing, and power generation.
Parker manufactures various kinds of cryogenic gate valves. These valves have a flexible wedge disc design that assures minimal leakage. Parker cryogenic gate valves have a diameter range from DN 40 to DN 100. The end connections can either be butt-weld or socket-weld, depending on the design. Made of stainless steel, Parker cryogenic gate valves have a maximum operating pressure of 580 psi or 40 bar, with an operating temperature range between -196 °C to 65 °C.
Velan is a industrial manufacturing giant that is active in several industries including nuclear power, power, oil & gas, LNG & cryogenics, and marine. This company has an extensive line of several industrial valves, including gate valves, globe valves, dual-plate check valves, among others.
Velan standard cast steel gate valves and API 602 small forged valves are adapted to cryogenic applications. These valves have a size range of NPS 2 to NPS 48 for the standard cast steel line while the API 602 line can have NPS ¼ to NPS 2 sizes. The pressure ratings for the cast steel cryogenic product line is from ASME Class 150- Class 1500. The API 602 product line has a pressure rating ranging from ASME Class 150 to ASME Class 2500. The end connections for all the lines can either be butt-weld, socket-weld or flanged.
