Brief: Explore what sets this solution apart in an easy-to-follow presentation. In this live demonstration, you'll see the Hard-Sealed Protective Gate Valve in action, engineered for extreme service environments. Watch as we showcase its robust construction, advanced metal-to-metal sealing technology, and performance under harsh conditions like corrosive media and high temperatures. Learn how its design ensures safety, reliability, and extended service life in demanding applications such as chemical processing, power generation, and oil & gas.
Related Product Features:
  • Advanced metal-to-metal sealing surfaces provide a bubble-tight seal for extreme pressure differentials.
  • Surface hardening treatment on critical components resists erosion and corrosion from harsh media.
  • Full-bore design minimizes pressure drop and prevents media accumulation in the pipeline.
  • Heavy-duty body construction uses ASTM-certified materials for specific media compatibility.
  • Enhanced stem protection with anti-blowout design prevents stem ejection under overpressure.
  • Suitable for corrosive, abrasive, and high-temperature/pressure applications up to 815°C.
  • Fail-safe design includes dual sealing systems and optional fire-safe construction.
  • Top-entry design allows simplified in-line maintenance without removing the valve from the pipeline.
FAQs:
  • What types of media is this Hard-Sealed Protective Gate Valve suitable for?
    This valve is engineered for harsh media applications, including corrosive fluids like acids and alkalis, abrasive slurries with particulates, and high-temperature/pressure conditions. It is also available in cryogenic service configurations for low-temperature applications.
  • How does the valve maintain sealing integrity under extreme conditions?
    The valve features advanced metal-to-metal sealing surfaces that are precision-machined and hardened to resist wear. Its self-compensating design maintains seal integrity despite thermal cycling, and it includes a dual sealing system with primary hard seals and secondary emergency capability for reliability.
  • What are the key safety features of this gate valve?
    Key safety features include an anti-blowout stem design to prevent ejection, multiple-stage stem sealing with live-loading for automatic adjustment, backseat function for safe packing replacement under pressure, and optional fire-safe construction to maintain sealing during fire exposure.
  • Can this valve be customized for specific operational needs?
    Yes, the valve offers various customization options, including material choices like stainless steel, duplex alloys, or titanium, different pressure classes from 150 to 2500, and preparation for manual, pneumatic, hydraulic, or electric actuation to suit your application requirements.
