Where are Durco valves made?
Located in Cookeville, Tennessee, Durco has been focused on meeting the high demands of industry since 1912, with a history of manufacturing valves in a wide range of specialized alloys. Strong engineering, metallurgy and research have produced a broad range of diverse plug and butterfly valves.
What is the other name of plug valve?
Such a plug is called bottom entry or inverted plug valve. Plug valves are also available with cylindrical plugs. The cylindrical plugs provide for larger port openings equal to or greater than the pipe flow area.

How many types of plug valves are there?
three
The three main types of non-lubricated plug valves are: Lift-type plug valve. Elastomer sleeved plug valve. Fully lined plug valve.
Why use a plug valve over a ball valve?
A plug valve has a conical or cylindrical disc with bored passages going through it. The disc or ball in a ball valve is smaller in size than the disc or plug in a plug valve. This is the reason why a plug valve is able to provide a tighter shut-off than a ball valve.
How does a plug valve work?
A plug valve is based on a plug with a hollow passage in the valve body. The quarter-turn motion creates an alignment between the pipe and the hole, leading to an open state. When turned to a 90-degree angle from the open position, the valve sits across the pipe leading to a closed state.
How old is Flowserve?
Our history began over 200 years ago, and today Flowserve employs more than 15,000 associates in 300-plus locations around the world, including over 180 quick response centers that provide aftermarket parts and services to customers.
Does a plug valve have a flow direction?
It uses a cylindrical or tapered plug (plug-shaped disk) to permit or prevent straight-through flow through the body. Plug valves offer a straightway passage through the ports so that fluid can flow through the opening plug with a minimum of turbulence. Flow can be in either direction with fully open or fully closed.
Are plug valves good for throttling?
A plug valve is an appropriate choice of valve for on-off or limited throttling applications in abrasive and erosive media as an alternative to metal seat ball valves or through conduit gate valves (Fig. 3.1).
Is plug valve full bore?
Plug Valve Disk Types Rectangular Port is the most common for a plug valve. The rectangular port represents at least 70% of the corresponding pipe’s cross-sectional area. Round port plug has a round opening through the plug. It is available in full bore and reduced bore design.
Why choose Durco valves?
The rugged design of Durco valves reduces maintenance, ensures longer service life, and is capable of adjustment inline under pressure. Operational expenses are reduced by the self-wiping action of the plug sleeve, which eliminates media buildup on the plug.
What is a Durco G4 plug valve?
The Durco G4 Sleeveline plug valve is engineered for use the most corrosive and difficult chemical services where drop-tight shutoff is an absolute requirement. It offers the proven reliability of the plug/PTFE sleeve primary seal with a fluoropolymer diaphragm secondary seal.
Are Durco pumps made by Flowserve?
During the same decade, Durco introduced the first fully Teflon-lined plug and butterfly valves. In 1997, Durco merged with BWIP, creating Flowserve Corporation. Durco pumps conform to ASME (ANSI) B73 standards for chemical process pumps and are available in a wide range of sizes for hydraulic coverage.
What is Durco made out of?
The company has created unique materials, including Durimet-20 (Alloy 20) high alloy austenitic stainless steel — developed and patented in a joint effort with Ohio State University — and Durcomet 100 (CD4MCuN) duplex stainless steel in the 1960s. During the same decade, Durco introduced the first fully Teflon-lined plug and butterfly valves.
