Floating Ball Valve with Worm Box Operated
Product Description
Material: Carbon Steel, Stainless Steel Nominal Pressure: ANSI CLASS 150-900 Structure: Floating Ball Valve Function: Blow-Down Valve Application: Industrial Usage Class: 150lbs-2500lbs Specification: API/ISO/CE/GB HS Code: 8481804090 Connection Form: Flange Channel: Straight Through Type Type: Floating Ball Valve Temperature: Normal Temperature Size: 4"~56" Trademark: FYV Origin: Wenzhou, Zhejiang, China CAST FLOATING Ball Valve
1. Bow-out proof stem
For the purpose of preventing the stem from flying off resulting in abnormal rising of the inner pressure of valve, shoulder is fixed at the lower part of the stem. In addition, in order to prevent leakage resulting from burnout of packing set of the stem in a fire, thrust bearing is set at the contact position of the shoulder at lower part of the stem and valve body. Thus an inverse seal seat is formed which will prevent leakage and avoid accident.
2. Key lock
Locks can be used to lock the manual valve when it is fully open or closed so as to prevent non-working personnel from pulling the handle which may result in misoperation of valve. It can also avoid opening or closing of valve resulting from the shock from pipelines or unpredictable factors that may cause an accident. For working pipelines such as combustible and explosive oil, gas and chemical medium, or for field piping site, the locking mechanism is especially useful.
3. Anti-fire safe design
When the Trunnion Ball Valve be used normally, its sealed by seat and ball surface, seat retainer sealed by O-Ring and body, this is soft sealed and reliable sealing. When the seat and O-ring are burnt, the seat retainer and body will be sealed by expanded graphite. Thus act anti-fire safe purpose.
4. Anti-static device
In order to prevent friction among ball, stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident, in this ball valve, static-conduction spring is set between the stem and the ball, the stem and the body. Thus static electricity is conducted to ground and system safety is secured.
6. Automatic body cavity relief
When the body pressure going up un-normally as the unstable factor, the trunnion ball valve downstream seat will be pushed by un-normally pressure, and the release the un-normally pressure automatically, it doesnt damage to the sealing of upstream seat. The unnormalpressure which in the floating ball valve body will release the pressure into the upstream pipe directly, it doesn't damage to the sealing of the downstream seat.
