The Cryogenic Gate Valve is a heavy-duty isolation valve designed to handle liquefied gases and low-temperature applications with precision and safety. Built from high-grade stainless steel and equipped with an extended bonnet, it ensures leak-free shutoff and smooth operation in environments reaching −196°C.
Available at Nassguard, the Cryogenic Gate Valve in Saudi is trusted by LNG terminals, petrochemical industries, and gas processing plants across Riyadh, Dammam, Jubail, Jeddah, and Al Khobar. Its robust design, corrosion-resistant materials, and international certifications make it ideal for critical cryogenic systems where reliable flow control is essential.
A cryogenic gate valve is a linear motion valve that controls the flow of cryogenic fluids such as LNG, liquid nitrogen, oxygen, hydrogen, and helium. It uses a gate disc that moves up and down to open or close the passage, providing a tight seal and unrestricted flow.
The valve’s extended bonnet isolates the stem packing from extremely cold temperatures, preventing frost buildup and ensuring long-term sealing performance in cryogenic service lines.
Extended Bonnet Design: Protects stem packing from frost and ensures smooth operation.
Low-Temperature Capability: Operates efficiently from −196°C to +80°C.
Full Bore Design: Offers unrestricted flow with minimal pressure drop.
Tight Shutoff: Metal or soft-seated gate ensures zero leakage.
Stainless Steel Construction: Made from AISI 316 / CF8M for corrosion resistance.
Fire-Safe Design: Built and tested according to API 607 / ISO 10497.
Blow-Out Proof Stem: Enhances operational safety under pressure.
Bidirectional Sealing: Provides reliable sealing in both flow directions.
Manual or Actuated Operation: Available with handwheel, pneumatic, or electric actuators.
Certified Compliance: Meets API, BS, CE, and ISO standards.
