What is PEC plug valve?
Design Features: DeZURIK Eccentric Plug Valves feature a rectangular port design that provides wide tolerance seating geometry for lasting superior shutoff. The eccentric plug action and resilient plug facings assure lasting dead-tight shutoff.
What is a PEF valve?
PEF valves are capable of handling clean and dirty liquids and gases, sludge and slurries. PEF valves come equipped with corrosion-resistant bearings, welded nickel seat, grit excluders, and adjustable steam seal packing, and meet AWWA C517 requirements for design and production testing.
What is the difference between ball valve and plug valve?
A ball valve has a hollow center and a spherical disc. A conical or cylindrical disc with drilled openings runs through a plug valve. In a ball valve, the disc or ball is smaller than the disc or plug in a plug valve. A plug valve can give a tighter shut-off than a ball valve because of this.
What is eccentric plug valve?
What is an eccentric plug valve? A style of rotary control valve with a plug-shaped, flow-restricting member that follows an eccentric path as it rotates. The plug has no contact with its seat until it turns within a few degrees of the shutoff position.
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.
What is face to face dimension of valve?
The face-to-face dimension for flanged Valves is the distance between the extreme ends which are the gasket contact surfaces. End-to-End dimensions apply to flanged Valves where the gasket contact surfaces are not located at the extreme ends of the Valve.
Why plug valves are used?
Besides being compact and using up less space, plug valves offer the following advantages: Flow Regulation – Tight shut-off, quick opening and low-pressure drop. Fire-safety and Durability – Reduced likelihood of corrosion or erosion as the actual plug and body seating surface do not get exposed to the line fluid.
Are plug valves directional?
Plug valves are high capacity valves that can be used for directional flow control, even in moderate vacuum systems.
How do you seat a plug valve?
When installing the plug valves, the seat end should be noted. The seat end of the valve is cast in raised letters on the appropriate flange of the valve. Generally, straightway valves should be installed with the highest pressure applied from the opposite end from the seat.
Where are DeZURIK valves manufactured?
In addition to the Sartell location, DeZURIK has manufacturing in Cambridge, Ontario; Redmond, Washington; Houston, Texas; and Gastonia, North Carolina to support the growing needs of its customers.
What is API 6D?
API-6D is the primary standard specification that defines the requirements for the design, manufacturing, assembly, testing and documentation of valves for application in pipeline and piping systems for the petroleum and natural gas industries.
What is iso5752?
This document specifies the basic series of face-to-face (FTF) and centre-to-face (CTF) dimensions for two-way metal valves of the gate, globe, diaphragm, ball, plug, butterfly design types used as isolating and check valves in flanged pipe systems.
Can you bury a plug valve?
The valves are typically shipped as either flanged or mechanical joint end valves and are equipped with a buried service manual worm gear. In most installations the valves are direct buried into the ground and cycled only a few times a year.
Who owns DeZURIK valve?

Does DeZURIK own APCO?
DeZURIK Completes the Acquisition of APCO Willamette Products and Operations. The acquisition of APCO Willamette by DeZURIK, Inc. has been completed effective April 1, 2011.
Do plug valves have a flow direction?
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.
What is API 6A and 6D?
Tony Mers • Jun 02, 2019. The American Petroleum Institute (or API) is an oil and gas industry trade association that oversees standards in oil and gas production. For example, API 6A defines the industry standards for wellhead and Christmas tree equipment and API 6D defines the industry standards for pipeline valves.
