plug valve

 
DESCRIPTION
Plug valves are valves with cylindrical “plugs” which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the open plug

DESCRIPTION

Gate valves are used when the requirements are: low flow resistance, simple design, high capacity, low cost and hermetic closing. The main features of gate valves are the sealing surfaces between the gate and seats
Godakhtar gate valves are reliable, offering a tight shut-off and low pressure drop. The design covers a wide range of requirements to meet any customer need from general to severe service conditions.
Godakhtar gate valves are in compliance with the latest edition of API 6D, API 6A, API 600, API 602, BS 1414, BS 5352 and ASME B16.34.
