Carbon Steel WCB Floating Ball Valve
Description of Product
Floating Ball Valve Specifications
Simple structure with good tightness and small torque;
Have reduce bore type and full bore type with the minimum flow resistance (zero actually);
Low emission packing;
Fire safe, anti-static and anti-blowout stem design;
Optional locking device;
Optional ISO 5211 top flange.
Floating Ball Valve Advantage
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 Application
Petroleum, chemical engineering, metallurgy, light industry, power station, city building, water supply system, oil transportation, gas feeding, natural gas and long distance transportation pipes projects.

Why Choose US
We control the material of PTFE(Teflon) and stainless steel wires per customer's request.
Some are from Japan and Taiwan, some are from China local. Only choose high quality material.
We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.
We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.
We use Techmaflex Crimping Machine which is imported from France. This machine has
accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
