Body is high flowrate design, large passage provides high volume and reduce flow resistance. ·Parabolic plug, V-port plug, balance plug and special design types are available. Also, the multi-holes cage for noise reduction is option. The soft seat plug is designed for working condition that have high sealing require- ments with zero leakage. The seat surface is welded with harden alloy. The harden metal surface reduces corrosion or cavitation damage. The leakage performance reaches ANSI FCI 70-2 standard class VI. It is reliable with long service life. ·The stem material is SS431 or SS316 with nitriding and grinding treatment, great mechanical properties with high strength, harden surface for long service life. The packing is available with choices of PTFE v-rings with spring loaded, pure graphite or metal bellows seal. Excellent performance for different
