Standard Features the purpose to increase only material has more the hardness of the plug toughness and resistance Carbon Steel plugs are subjected to the following treatments: A Case hardening. B Antifriction treatment. A) The case hardening has surface which is subjected to wearing, keeping at the same time the mechanical properties of the base material unchanged. Consequently the base against impacts. B) The Antifriction treatment is basically carried out on the plug to obtain the following advantages: - Low friction between plug and body. Low torque. Wear resistance. Resistance to...

Pattern Full Bore Plug Valves have API-6D face to face dimensions and a round port that is not smaller than the minimum diameter specified in Annex A of ASME B16.34 or/and API 6D. This configuration provides unrestricted flow and allows the passage of pigs through the valve. It is recommended for highly abrasive services and low pressure drop as well. Lubricated Plug Valves are designed to use with most refining and gas pipelines services according to API 599 or BS 5353 norms whichever applicable. API 6D norm aims to standardize the materials as well as instructions to manufacture valves...

Advanced Design

Full Bore LGC Plug Valves Galli&Cassina is proud to introduce a new line of ”FullBore,Pressure Balanced” plug valves with LGC* (Low Grease Contamination) lubrication system. Galli&Cassina has designed this new “Full Bore” plug valve in response to customer requests to provide a plug valve with the distinctive features of a ball valve for Energy applications, but with less lubrication requirements than a traditional plug valve. Thus, the LGC lubrication system of the“Full Bore” plug valve has been improved to minimize the area of contact between the fluid and the lubrication system when the...
