Our 300LB Cast Steel Floating Ball Valve With ANSI 300# full bore 2 piece Ball Valve. A WCB body and stainless steel 316 ball, with RPTFE seats for High Temperatures. Principle of the cast steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet, floating ball valve is mainly used in middle or low pressure application.

3 Piece Ball Valve is a fully maintainable three piece, full bore ball valve;,providing a cost-effective solution for ‘shut-off’ and isolation of low temperature steam duty and medium flows.

The working principle of our 150LB Forged Steel Ball Valve  is to rotate the valve stem to make the valve unblocked or occluded. It can be full-bore ball valve, 90°C angle, ball valve switch is light, small in size, can be made into large diameter, reliable in sealing, simple in structure, convenient in maintenance, sealing surface and spherical surface are often closed, not easily eroded by medium, in various industries. Widely used.

1500LB Pressure Seal Gate Valve, WC6 Body, DN250,Flange End. 1500 LB Pressure Seal Gate Valve is mainly used in the pipeline of the fire station in a variety of systems, cut off or connected piping media. Applicable medium: water, steam and other non corrosive media. Compared to the power station valves and other valve products is characterized by high temperature and high pressure, the unique self seal design, the higher the pressure, sealing more reliable. Due to the special properties of technical characteristics, conditions of formation of the products can not be replaced by other product characteristics.

24 Inch API 600 Carbon Steel Flanged Gate Valve,ANSI 150lb, Gear Box OP. 24 Inch API 600 Carbon Steel Flanged Gate Valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening.
