Pressure Seal Gate Valves

Pressure seal gate valves are primarily used in high-pressure and high-temperature applications due to their robust design and reliable performance. Here are some key reasons for their application:

Leak-Proof Seal: The pressure seal design ensures a tight, leak-proof seal that becomes more effective as the system pressure increases.

Durability: These valves are made from thick-walled forgings or castings, making them highly durable and suitable for demanding environments.

High-Pressure and High-Temperature Handling: They are specifically designed to handle extreme conditions, making them ideal for industries like oil and gas, power generation, and petrochemicals.

Safety: The pressure seal bonnet provides a secondary seal, enhancing safety by reducing the risk of leaks.

Space Efficiency: The non-rising stem design is beneficial in applications where vertical space is limited.

These features make pressure seal gate valves a popular choice for critical applications where performance and safety are paramount.

We supply Gate valves designed to ASME / API standards with flanged ends or butt weld ends, pressure seal design, body of forged or cast material, non-rotating stem, split wedge with flexible mounted discs for precise alignment with the body seats. Seat/disc interface made of wear and corrosion resistant stainless steel or Stellite.
