Stainless Steel Plug Valves Advantages
ZZJG VALVE's Plug valve, opening and closing part (cone plug or ball) Rotating around its own centerline, the plug valve is a valve that uses a plug body with a through hole as the opening and closing part, and realizes the opening and closing action through the rotation of the plug body and the valve stem. The plug valve has simple structure, rapid opening and closing, and low fluid resistance. In recent years, as one of the first valves used in history, not only has it not been replaced by ball valves and other types of valves, but the market is showing an increasingly popular trend.
ZZJG VALVE's stainless steel plug valves stand out for their exceptional durability and corrosion resistance, engineered to thrive in harsh industrial environments—from chemical processing to offshore oil & gas operations. Crafted with high-grade 304/316 stainless steel, these valves resist rust, acid, and extreme temperatures, ensuring long-term reliability even under heavy-duty use. Backed by over 40 years of manufacturing expertise, ZZJG VALVE optimizes every component for structural integrity, minimizing leakage risks and extending service life for global clients.
1. The inlet and outlet window of the valve body is designed as a double-channel grooved sealing ring structure. During the rotation of the cock, the sealing specific pressure between the sealing pairs gradually changes until it reaches the fully open or fully closed position, resulting in sufficient sealing. Specific pressure, the sealing pair reaches zero leakage.
2. The double-channel grooved sealing ring can not only make the PTFE bushing stable in the valve body without displacement, but also absorb the slight deformation of the bushing caused by the temperature difference, and at the same time produce a strong wiping effect between the bushing and the cock, and Improve the service life of the sealing surface.
3. The entire sealing process can be approximately regarded as having nothing to do with the pressure in the pipeline.
4. In the PTFE bushing, according to the use temperature and working medium, different materials are used as fillers, which are lubricated and have a long life.
Designed for efficiency and versatility, ZZJG VALVE's stainless steel plug valves feature smooth operation and tight sealing performance, reducing maintenance costs and improving system productivity. Whether handling viscous fluids, high-pressure gases, or corrosive media, these valves offer precise flow control with low torque requirements, adapting to diverse industrial applications. As a trusted supplier in international markets, ZZJG VALVE combines rigorous quality control with customizable solutions—tailoring valve sizes, pressure ratings, and connection types to meet specific project needs, while upholding the brand’s commitment to excellence since 1981.
