Fixed ball characteristics and titanium plate

1, two obstruction and discharge function : Fixed ball valve spring preload floating seat when the valve is either fully open or fully closed state , on the downstream side of the valve seat to block fluid , the valve body cavity left by the discharge valve excretion .
2 , automatic pressure relief function: the valve body cavity stays medium temperature caused when abnormal pressure , without going through the safety valve, which can function alone automatic pressure relief valve , this valve to ensure safety in the transportation of liquid medium is very important .
3 , fire safety structure: Valves are equipped with fire safety features, its design, manufacture and API6FA were followed API607 specifications.
1 , sealing grease emergency ambulance : As media objects or accidental fire caused seat bolt seals failure , grease valve provides a quick connection to the grease gun , pump inlet seal fat quickly and easily injected into the valve seat sealing parts , ease leak.
2 , reliable stem seal and low operating torque: In addition to setting the standard pull tite seals rings , but also set up the packing gland "O" -ring, double sealed to ensure the reliability of the valve stem seals ; additional graphite packing and plastic strap seals fat injection to stem the leak after the fire to a minimum. Stem sliding bearings and thrust bearings easy operation of the valve .
3 , full bore or reduced bore : may need to use full bore or reduced bore structure. Full Bore Valve flow aperture is consistent with the internal diameter of the pipeline , the pipeline for easy cleaning .
4 , the stem can be lengthened : required installation or operation of the valve stem can be lengthened . Extensions ball , especially for city gas pipeline laying underground and other needs of the occasion. Long stem size is determined by customer needs .
5 , flexible operation : using a small friction coefficient and excellent self-lubricating bearing seat and a valve stem , the valve is greatly reduced operating torque . Therefore, even in the case of not providing a sealing grease , can be flexible and comfortable for the long-term operation of the valve .
