Design criteria:	API 6D, ASME B16.34, API 608
Body material:	WCB, LCB, CF8, CF8M, CF3M Etc.（A105, LF2, F304, F316, F316L Etc.）
Sphere material:	13Cr, SS304, SS316, SS316L Etc.
Seat material:	PTFE, RPTFE, PEEK, NYLON
Stress:	150LB to 1500LB
Size:	1/2" to 10"
Connection:	Flange, welding, thread
Materials:	Carbon steel, stainless steel, etc.

·Fire and anti-static design. When the flame burns the soft sealing material, the metal sealing material will cut off the flow of the valve medium.
·Optional extended stem. Extended STEM to meet customer needs to adapt to any situation.
·Safety locking device. The valve is equipped with a complete locking device to prevent the valve from being switched on and off at will by others.
·Blowout preventer stem design. It has a tapered sealing surface that allows for replacement of packing when the valve is opened.
·Optional Operation Mode. Turbine, electric or pneumatic devices may be used if required.
