fix ball valve performance advantages
Fix ball Valve performance advantages
1, Effortless operation: the ball from the upper and
lower bearing support, reduce friction, eliminate excessive torque caused by the
inlet pressure to promote the sphere and the sealing seat and a huge load of
seal.
2, sealing performance and reliable: PTFE unisexual material ring
embedded in the stainless steel seat, metal seat the end has a spring to ensure
adequate seals preload, valve sealing surface wear and tear during use, the
spring action under the valve will continue to ensure good sealing
performance.
3, the structural fire protection: in order to prevent the
sudden heat or fire, PTFE seals burned, the occurrence of a large leak, while
fueling the fire set fire to seal between the ball and valve seat ring, the ring
burned, In the spring force, the seat seal ring to quickly push the sphere to
form a metal to metal seal, play a certain degree of sealing effect. Fire Test
comply with APl6FA, and APl607 standards.
4, the automatic pressure relief
feature: When the medium pressure valve in the cavity of stagnation unusual
increase in the pre-force exceeds the spring seat back out of the sphere, the
effect of the automatic pressure relief, pressure relief seat automatically
reset after
5, the upper and lower excretion of the pipeline: the valve body
are set to vent, you can check whether the valve seat leak, at work, the valve
is fully open or fully closed, dismantled in the cavity pressure can directly
replace the packing; emissions can The cavity left in it to reduce the pollution
of the media on the valve.
