Description
The ball adopts the floating structure. The single-way force acted by the medium on the ball makes the ball Move closer to one side of the PTFE seat. The sealing function is realized through extruding the seat .It is mainly used for shut-off applications in low pressure service conditions. The 50FSeries valve is an ideal product used for on-off in the pipes. Featured by compact structure, light weight, high flowing capacity, strong shut-off performance, long service life, etc., it is the best choice in steam, hydrocarbon, corrosive media and other service conditions. It has prominent performance sespecially in chemical industry, air separation, water supply system, etc. It is an ideal choice of users.

Stem sealing
The graphite packing formed through mold pressure serves as the dynamic load seal to ensure reliable sealing and long service life.
The high strength stem can effectively transfer torque and ensure reliable on-off of the valve.
The stem and ball fit tightly with each other, reducing hysteresis and dead band with excellent control performance.
Seat sealing
The seal conforms to the requirements in GB/T13927 Class D or ANSI/FCI70-2 CLASSVI.
Reliable double-way sealing
Excellent sealing performance in low pressure service conditions
