产品概览

Our hard seal wedge gate valve is engineered for critical service applications requiring metal-to-metal sealing without elastomers. Featuring a precision-machined solid wedge design, it delivers bubble-tight shutoff in high-pressure, high-temperature, and abrasive media applications where soft-seated valves fail prematurely.

主要功能

1. Uncompromising Sealing Performance

  • Metal seat Class IV shutoff per API 598 (option for Class VI with special lapping)
  • Bidirectional sealing capability for versatile installation
  • Stellite 6 or 21 hard-faced seating surfaces (HRC 40-45)

2. Heavy-Duty Construction

  • Full-bore design minimizes pressure drop
  • Rising stem with blowout-proof design
  • Integral seat construction eliminates seat loosening

3. Extreme Service Capability

  • Temperature range: -29°C to 550°C (-20°F to 1022°F)
  • Pressure rating: Class 150 to 2500 (PN16 to PN420)
  • Abrasion resistant: Ideal for catalyst, slurry, and steam services

总结

The hard seal wedge gate valve provides superior longevity and reliability in extreme service conditions where soft-seated valves fail. With Stellite-hardened seating surfaces, fire-safe construction, and API 603 compliance, it’s the optimal choice for critical isolation applications in oil & gas, power, and heavy industries.
