Features:
1, advanced isostatic pressing PTFE (PTFE) seat, with the traditional molding method than the high density uniformity, more than 2.16g / cm3 uniform density, at least 3mm thickness, to ensure that the material low permeability Rate, extend the service life of the valve;
2, the valve plate substrate with high-quality duplex stainless steel integrated casting (no welding) to achieve due to dielectric jamming and other sudden increase in the case of stem seal safety, the maximum valve stem leak safety protection, High-level melt flow rate PFA, with higher thermoplastic and temperature resistance, to ensure excellent zero leakage and media safety
3, the valve plate and the seat of the sealed form of spherical sealing, sealing performance better, effectively reduce the flow resistance;
