Side entry type stainless steel floating ball valve Design Features
1. Anti blow-out stem : 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.
2. Anti static device, thus static electricity is conducted to ground and system safety is secured.
3. Fire safe design API 607 Soft Seat or metal seat, Side entry.

 Class 150~600 LB Floating Ball valve  Advantage:
1. The fluid resistance is small, its resistance coefficient with section of equal length.
2. Simple structure, small volume, light weight.
3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.
4. Easy to operate, open and close quickly
5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.
6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
