API 6A stainless steel / carbon steel gate valve
Product Overview
1.Gate valve is mainly used to control the connection and disconnection of piping and other equipment medium. As the core part of wellhead for production, gate valve has the function of connecting and disconnecting piping medium and control and fluid direction. It is mainly used in drilling oil production system, such as kill manifold, choke manifold, mud manifold, standpipe manifold, drilling fluid manifold and other high pressure manifold. There are rising stem gate valve and non-rising stem gate valve;
2.Flange gate valve is available in 2-1/16",2-9/16",3-1/8",4-1/16";
3.Hammer union gate valve is available in 1'', 2'', 3'', 4'', and union head is available in fig602 buckle type, fig1002 buckle type and fig1502 buckle type;
4.The rated working pressure is within 42MPa(6000psi)~105MPa(15000psi).
Design Features
1.High pressure gate valve has low moment of force when opening under pressure due to its straight-through type runner;
2.Both outlet joints are flange, thread and union head, and all designs are in keeping with API 6A Standard;
3.Processed by heat spray welding, the valve plate and valve seat are of high stiffness and abrasion performance;
4.The valve body of high pressure gate valve is an solid forging, which ensures the high strength and pressure bearing;
5.Simple operation, reliable sealing, smooth runner, low flow resistance and long life span;
6.Simple and compact structure, fine manufacturing technology and low costing;
7.When the high pressure gate valve is in the status of full opening or full closing, closure members are hardly getting erosion by medium, which ensures reliable working under high pressure.
