FLOWORK Plug Valves are of diverse types, sizes and pressure ratings to adapt to different operating conditions. Our valves are in high quality and high user satisfaction, complying with the strictest international standards involving API 6D, API 599, API 598, API-Q1, CE, ISO 9001, ISO 45001, ISO 14001, ISO 15848-1, etc. We can also manufacture customized plug valves to meet specific industrial requirements. What is a plug valve? A plug valve is a valve with cylindrical or conically tapered plugs which are rotated with stem to open or close the valve. Plug valves are suitable for cutting-off, connecting and bypassing usage. Plug valves can be designed into multi-port structure (two ports, three ports, or even four ports). They are of simple structure, small fluid resistance, and high sealing performance. What's the main design standards of FLOWORK plug valves? FLOWORK Plug Valves are mainly manufactured according to API standard, such as API6D Plug Valves and API 599 Plug Valves. Additionally, DIN Plug Valves are available to adapt to different specifications. What's the type of material of your plug valves? FLOWORK manufactures plug valves in various materials, involving Bronze Plug Valves (C95800, C95500, C95400, C83600, etc.), Cast Steel Plug Valves(WCB, WCC, LCB, LCC, etc.), Special Steel Plug Valves (Monel, 4A, 5A, etc.), Special Alloy Plug Valves (Alloy 20, CN7M, Inconel Alloy, Titanium Alloy, etc.), Stainless Steel Plug Valves(CF8, CF8M, CF3, CF3M, CF8C, etc.), Forged Steel Plug Valves(A105, LF2, F5, F11, F22, F91, etc.), Alloy Plug Valves (WC6, WC9, C5, C12, etc.), Super Stainless Steel Plug Valves(Monel, CD4MCU, CD3MN, 904L, etc.), Ductile Iron Plug Valves (GGG40, GGG50, etc.), Hastelloy Plug Valves, etc. Plug valve types and application: Lubricated Plug Valves: divided into Conventional Lubricated Plug Valves and Pressure Balanced Plug Valves; usually have the sealing structure of lubricating the seat with sealing grease; small torque. Pressure Balanced Plug Valves: compulsory grease-filled compensating seal; inverted cone; small torque; mainly applied to long-distance gas pipelines, especially the severe operating conditions. Non-lubricated Plug Valves: mainly applied to petrochemical and oil refining industries; less friction; flexible plug; long service-life. High Temperature Plug Valves: applicable for high temperature applications. Jacket Plug Valves: divided into Full Jacket Plug Valves and Partial Jacket Plug Valves; designed to prevent liquid temperature loss. Hard Seal Plug Valves: small fluid resistance; sealing surface is not likely to be scoured by medium; high sealing performance; applicable for a wider range of temperature and pressure rating. Soft Seal Plug Valves: generally applicable for harsh environment with corrosive, highly toxic and harmful medium and for occasions where are required zero leakage. Lifted Plug Valves (Lifting Plug Valves) : divided into hard seal and soft seal plug valves according to different sealing surface materials; with no wear on sealing surface when opening and closing; suitable for working temperature from -29℃ to 550℃. General Plug Valves: with less friction on sealing surface; small torque; suitable for pipelines of natural gas, liquefied gas, chemical media, etc. FLOWORK Big Size Plug Valves come up to 40 inches. FLOWORK also produces other types of plug valves, involving DBB Plug Valves, Sleeve Plug Valves, Inverted Plug Valves, Expanding Plug Valves, etc. Plug valve types according to operation: •Hand Wheel Plug Valves •Lever Operated Plug Valves / Wrench Operated Plug Valves •Gear Operated Plug Valves / Worm Operated Plug Valves •Motorized Plug Valves •Pneumatic Actuator Plug Valves •Hydraulic Actuated Plug Valves Plug valve types according to connection: •Flanged Plug Valves •Butt Weld Plug Valves / BW Ends Plug Valves •Socket Weld Plug Valves / SW Ends Plug Valves •Screwed Plug Valves •NPT Plug Valves
