Carbon Steel Plug Valve

Carbon steel plug valve is a carbon steel (such as WCB, A105, etc.) as the main material of the plug valve, through the through-hole conical or cylindrical plug body rotated 90 ° to achieve the media opening and closing or flow control, its core structural features, specifications range and industry applications are as follows:
Structural features
Compact valve body design
Integral cast carbon steel valve body (ASTM A216 WCB), the internal flow path for the very low resistance of the straight-through structure, the flow efficiency> 85%.
Dual sealing system
Soft sealing type: the plug body is covered with PTFE or rubber, and the valve seat adopts double groove sealing ring structure, which improves the thermal deformation compensation ability by 40%;
Hard sealing type: the surface of the plug body is surfaced with hard alloy (such as tungsten carbide), which forms a high-pressure oil film seal with the oil injection system.
Low torque transmission
Valve stem and plug body integrated forging, the use of self-lubricating bearings, opening and closing torque is 70% lower than traditional valves.

Advantages

Economical and efficient
The cost of carbon steel is only 50% of stainless steel valves, low maintenance costs.
Wear-resistant and anti-clogging
Rectangular flow path design can transport media containing crystalline particles (such as slurry, sewage).
Flexible operation
Support manual, pneumatic, electric drive, 90 ° fast opening and closing (time <1 second).
Reliable sealing
The soft seal type reaches ANSI B16.104 Class VI zero leakage, and the hard seal type has a pressure resistance of 64MPa.
