And we are not related to any other website. The size of a valve is mainly determined by the size of its ends, which connect to the pipe. Butterfly valve: - They are quarter turn positive shut off valve. Soft seats are usually used only for low temperature services. The Bonnet is classified on the type of attachment as Bolted, Bellow, Sealed, Screwed-on, Welded, Union, Pressure Sealed etc. Based on sealing, Lubricated metal seated plug valves: The lubrication of the seating surfaces is by means of lubricant,which is fed into the operating surfaces. Normally the port diameter is one size less than the pipe diameter. As a thumb rule, gear operators should be considered for valves of 350 mm NB and larger upto 300200 mm NB and larger upto 600150 mm NB and larger upto 1500 and 100 mm NB and larger for higher ratings. DIAPHRAGM VALVE: - These valves are used for low pressure corrosive services as shut off valve. Method of operating stem: consider closing time. In fact a pressure relief valve has the same construction as a spring operated check valve. These are less stringent than other standards.
Butterfly valve: - They are quarter turn positive shut off valve. As a thumb rule, gear operators should be considered for valves of 350 mm NB and larger upto 300200 mm NB and larger upto 600150 mm NB and larger upto 1500 and 100 mm NB and larger for higher ratings. For manual operation, it consists of a hand wheel operated gear train actuating the valve stem. Based on sealing, Lubricated metal seated plug valves: The lubrication of the seating surfaces is by means of lubricant,which is fed into the operating surfaces. MANUAL OPERATORS 1 Hand lever: It is used to actuate the stems of small butterfly, ball, plug valves and cocks.
Different devices are available. Normally the port diameter is one size less than the pipe diameter. VALVES Valve: Any Device for closing or modifying the passage through a pipe, outlet, inlet or likely to stop, allow or control the flow of a media. DIAPHRAGM VALVE: - These valves are used for low pressure corrosive services as shut off valve. PROXIMITY SWITCH FOR STAND-BY VALVES GAS-FREEING COVER WITH SIGHT GLASS FOR VAC DISC POSITION SELF-CLOSING VALVE TO PREVENT CARGO ESCAPE FROM SUNKEN VESSEL DESICATOR TO PREVENT DAMAGE TO HYGROSCOPIC CARGO 2. This is useful for operating large valves in remote areas. The end flanges can be integrally cast into the body. Offers minimum resistance to flow. Slurry: Suspension of solid particles in the fluid media.

Fig shows how a control valve can be used to control the rate of flow in a line. Different devices are available.
Installation problems:Such as welding valves into lines. Butterfly valve: - They are quarter turn positive shut off valve. Check Valve to be erected in Horizontal and according to the flow of direction marked in the valve.
