BALL VALVE FORGED STEEL CAST IRON STEEL
Product Description :
Body integral structure: The body adopts an integral side entry structure with good structural rigidity, which does not easily cause external leakage.
Upward and downward self-lubricating bearing: The body is installed with upward and downward lubricating bearing, which has high contact area with the stem, high carrying capacity, low friction coefficient, so that the valve torque is reduced.
According to the requirements for media and service conditions, the seat can use metal hard seal or PTFE soft seal: The sealing face of the metal hard seal seat is subject to hard alloy overlaying welding, the ball face is subject to hard chrome plating or spray welding, ion nitriding and other hardening treatment, so as to prolong service life of the sealing face and improve heat resistance. The soft seal PTFE seat or reinforced PTFE seat has good sealing performance, corrosion resistance and wide application range.
