API forged flanged gate valve

API forged flanged gate valve

API forged flanged gate valve is a gate valve with a flange on one side for attachment to another object that are forged in accordance to the American Petroleum Institute. The main parts of API forged flanged gate valve are body, seat ring, wedge, stem, bonnet bolt, bonnet nut, gasket, bonnet, backseatbushing, packing and hand wheel. Its materials are forged and they are A105; F5; F9; F11; F22; F91; F304; F3. API forged flanged gate valve is suitable for high pressure. It can stand pressure from class800 to 2500LB. The size of API forged flanged gate valve is 1/4"~2". Oil, water and so on are the ideal medium for API forged flanged gate valve. Low temperature is applicable for the media. Meanwhile, it is certified by ISO9001,API6D,CQC,PDO. As for the application standard, forged flange API gate valve’s design and manufacture must conform to: API 602 and connection ends conform to:  1) Socket welded dimension conform to ANSI B 16.11. 2) Screw thread dimension conform to ANSI B 1.20.1.what’s more, the test and inspection of Forged flange API gate valve conforms to conform to: API 598.

API forged flanged gate valve is actually is a kind of gate valves. Therefore, it has the same working principle of gate valves. API forged flanged gate valve is used for cut-off the medium, when full open the flow through the whole pipe, when the media running, there have a minimum of pressure loss. API forged flanged gate valve is usually used for the working environments which do not use frequently and keep the disc full-or full-closed. But it does not applicable to regulator or reducing the medium. When the flow of medium is high-speed, the disc to open at local conditions can cause the vibration of the disc, and the vibration damper may damage the disc.
