The central section of the pressure seal globe valve features a pressure self-tightening mechanism, ensuring excellent sealing performance even under extreme high-pressure and high-temperature conditions. Typically, the sealing ring is crafted from either low-carbon steel or a combination of flexible graphite and SS 316. Additionally, the sealing surface undergoes hard alloy welding, with a minimum metal layer thickness of 3mm, offering remarkable wear resistance, temperature resilience, and corrosion protection. This configuration significantly extends the valve's operational lifespan.

Both ends of the valve employ a welded structure, with the welding groove dimensions customizable based on client specifications. Suitable for conveying high-temperature and high-pressure fluids such as water, steam, oil products, and superheated steam, this valve finds wide application across thermal power plants, petrochemical industries, metallurgical facilities, and various other industrial sectors.
