API 6A FC TYPE Wellhead Valves Manual Gate Valve
Gate valve structure characteristics For API 6A Gate valve:
The design confIrms to the API Spec 6 a standard and API Q1.
1.Sealing for Body and cover is metal to metal seal, improve the sealing performance.
2.stem and cover designed with backseat sealing structure is easy to take pressure change
valve stem packing.
3.The body is made of high quality alloy steel forgings, no perforation design, safe and reliable.
4.Sealing surface spray weld hard alloy, with corrosion resistance, resistance to erosion and wear
resistance performance.
5.Body pad ring groove can according to user requirements overlaying austenitic stainless steel,
improve the corrosion resistant ability; To enhance its service life.
6.Use spring preload load in the disc and seat, completely realize two-way seal.
Set to open and close just device, shows that the valve open and close condition, operating torque low.
