Forged Steel Gate Valve Manufacturers in China
Forged steel gate valves are made of an alloy consisting of iron and carbon. This alloy is compressed at high pressure which results in a less porous surface, finer grain, improved tensile strength, and higher ductility compared to other kinds of steel. Forged steel gate valves are often devoid of gas pockets that could lead to load failure. These gate valves are often used in oil & gas industry, air & ship industry, automotive industry, and agriculture machinery.
Yuanda Valves offers its services to the petrochemical, electric power, and chemical industries, among others. This valve company produces several kinds of industrial valves, including cast steel gate valve, globe valve, check valves, butterfly valves, ball valves, strainers, compensators, and other industrial components.
Yuanda Valves produces three kinds of forged steel gate valves: the flanged end gate valve,
Z41Y H-25/40/64/100/160 grade forged Steel Gate Valve and Class 150-800 forged steel gate valve. These valves are suitable for vapor, water and oil applications. Yuanda Valves can work optimally from -29℃ to 425℃. The flanged end type has a pressure rating ranging from Class 150 to Class 2500, with valve diameter ranging from ¼” to 2 1/1”. The Z41Y type can reach up to 16.0 MPa with DN ranging from 15 to 40. On the other hand, the Class 150-800 variant has a size range of ¼” to 2”.
Beijing Valve General Factory Co.
Beijing Valve General Factory Co or BVMC is a producer of ball valves, gate valves, and globe valves. This company holds several certifications, including ISO 9001, API6D, API 6A, API 607, API 6Fa, CE, CRN, CUTR, and CCS. The company provides its industrial valves to petroleum, natural gas, chemical and metallurgy industries, among others.
BVMC non-rising flat gate valve is made of forged steel. This valve type has a size range for NPS 2 until NPS 60. Also, the non-rising flat gate valve can optimally work between -196℃ to 593℃, depending on the media. This valve has a standard design based on API 6D and ASME B16.34. The face dimensions of this valve follow the ASME B16.10 standards. The end connections of this valve type follow the guidelines of ASME B16.5, ASME B16.47, and ASME B16.25. Valves under this type can be operated manually, electrically, and pneumatically.
Automatic Type Gate Valve Manufacturers in China
Automatic gate valves are a special kind of industrial valves that not only isolate different kinds of media but also provide a fail-safe option for high torque multi-turn or rotational valves. It becomes difficult to manually operate gate valves when the pressure is high. This kind of gate valve is also a cost-effective solution when gate valves are used for the terminal operation. Automatic gate valves are commonly found in sewage system operations.
Landee manufactures a wide range of industrial valves. The product lines of the company include four types of ball and check valves, 220v solenoid valve, three kinds of butterfly and globe valves, two kinds of plug valves as well as numerous industrial valve components. Landee engages in chemical, construction, mining, oil & gas, power and water treatment industries.
Landee solid parallel-faced gate valve is an automatic gate valve with a solid wedge gate disc and wafer end connections. This valve follows the ANSI B16.10 and API 598 design standards. Its face to face dimensions follow the ANSI B16.10 guidelines. The automatic gate valve has floating seats with PTFE inserts. The flanges of this valve have standard 24” as per ANSI B16.5 design guidelines, but these can reach wider diameters as well, depending on customer preferences. This automatic gate valve assures total upstream and downstream seals.
Shanxi Solid Valve
Shanxi Solid Valve is one of the leading valve manufacturers in Shanxi, China. The company offers a wide array of pipeline products such as pipe fittings, steel pipes, flange adaptors and a wide range of industrial valves. This company is approved by TUV Rheinland and carries certifications such as WRAS, CE and ISO 9001.
Shanxi Solid ANSI F4 DN 150 rubber wedge automatic gate valves are made of cast ductile iron. These valves are used for water, sewage, oil and gas applications. They are designed according to ANSI/AWWA C509, BS5163, BS 5150 and DIN 3352 design standards, Shanxi Solid automatic gate valves have valve diameters ranging from DN40 to DN1200 and have pressure rating that ranges from 1MPa to 1.6MPa. These valves can work best when the temperature does not exceed 120℃. Shanxi Solid automatic gate valves can have NBR, EPDM or FPM seat materials.
Pressure Seal Type China Gate Valve Manufacturers
Pressure seal gate valves use the system pressure to effectively seal leak-prone areas of the valves such as the bonnet area. Such valves are used for high-pressure services, often more than 170 bar. One distinguishing characteristic of the pressure seal gate valve is that as the internal pressure increases, the connection between the body and the bonnet becomes tighter, leading to better sealing. Simply put, the higher the pressure, the greater the sealing capacity of these kinds of valves.
Cengon offers an extensive collection of industrial valves, including ball valves, gate valves, plug valves, and butterfly valves. The company is a holder of several international standards certificates such as API 607, ECM Certificate of Compliance, ECM Full Quality Assurance System Certificate, ISET, OHSAS 18009:2007 and ISO 9001:2008.
Cengon pressure seal CG gate valve has a self-tightening bolt-bonnet joints feature, something very useful for high pressure and temperature applications. This pressure seal gate valve follows the API 600 and ASME B 16.34 design standards. The Cengon pressure seal gate valve can withstand up to 2500lbs of pressure. This valve has a size range from 2” to 30”, and its body material can be made of carbon steel, stainless steel, duplex stainless steel, alloy steel, and nickel alloy. Cengon pressure seal valves can be operated manually, pneumatically, electrically, and hydraulically.
