High pressure forged steel valve pneumatic ball valve:
1. The stagnation of valve lumen medium due to temperature change people often booster, medium pressure push out of the sphere, the seat to achieve the effect of pressure relief automatically, after pressure relief valve seat automatic reset.
2. In addition to general seating, set sealing structure in particular, can play because of the sealing ring damage when leak emergency rescue action.
3. When the fire or different temperature to soften seat sealing loss or when. Valve operation is still reliable, at the same time, the seat and sphere form metal to metal, to temporarily seal effect, to prevent fire is widening.
4. Unscrew out device can check whether the valve seat leakage occurs, can discharge midplane retentate to valve's unilateral medium to reduce pollution. In working status, when the valve is in full open or close, can replace the valve stem packing.
5. The stem parts adopt PTFE packing and double sealing o-ring, especially suitable for the gas medium. Stem movement parts adopt high quality self-lubricating bearings, make smaller friction coefficient, reduce operating torque.
