Product Description
Discover the ultimate in reliability and innovation with our High Temperature Control Valves and Ball Valves designed for Heavy Duty Use. This state-of-the-art series guarantees unrivaled Zero-Leakage performance, tailored specifically for demanding service applications characterized by extreme temperatures and high pressure conditions.
Craftsmanship meets durability with our advanced ball and seat construction, meticulously hard-coated using superior chrome carbide or tungsten carbide. These materials are renowned for their exceptional erosion and abrasion resistance, ensuring longevity and robust performance across diverse environments.
At SNT Machinery (Qingdao) Co., Ltd., we utilize the cutting-edge HVOF coating system. Our proprietary mate-lapping technique ensures impeccable 100% sealing. Additionally, our innovative live loading design guarantees zero emissions. The ball remains in constant contact with the seat, effectively wiping away contaminants through a self-cleaning action. This feature makes our valves ideal for slurry and abrasive service applications, as it prevents damage and interference from harmful particles.
