Ditch the generic valves that fail at cryogenic temperatures or compromise insulation! Our Thermal Insulated Pneumatic Diaphragm 2-Way Globe Valve is built for the extreme conditions of cryogenic liquid regulation: advanced thermal insulation prevents heat ingress (avoiding cryogenic fluid boil-off and product waste), while the pneumatic diaphragm actuation ensures fast, precise flow control. The 2-way globe design delivers excellent throttling performance, making it ideal for regulating cryogenic liquids with tight flow control requirements. Say goodbye to leaky valves, inefficient insulation, and imprecise regulation—this is the cryogenic control valve your facility needs to keep operations safe and efficient.

When regulating cryogenic liquids, thermal insulation is non-negotiable—and our valve delivers industry-leading insulation to protect your cryogenic fluids and reduce waste:

• Advanced Thermal Insulation Layer: Valve body and bonnet are wrapped in high-density PIR/PUR insulation (thickness 50-100mm) with a protective stainless steel jacket, minimizing heat transfer and preventing ambient heat from entering the valve. Reduces cryogenic fluid boil-off by 80-90% compared to non-insulated valves.
• Low Temperature Resistance: Engineered to operate reliably at ultra-low cryogenic temperatures (down to -196℃), compatible with all common cryogenic liquids—LNG (liquefied natural gas), liquid nitrogen (LN2), liquid oxygen (LOX), liquid argon, and liquid CO2. Maintains structural integrity and insulation performance even in extreme cold.
• Condensation Prevention: Insulation layer prevents external condensation and frost buildup on the valve surface, reducing the risk of ice formation that can damage valve components or pose safety hazards in industrial environments.

This 2-way globe control valve features pneumatic diaphragm actuation—perfect for precise regulation of cryogenic liquids, with smooth operation and minimal maintenance:

• Pneumatic Diaphragm Actuator: High-sensitivity diaphragm actuator (spring-return or double-acting) delivers precise flow control, with adjustable stroke (10-50mm) for accurate throttling of cryogenic liquids. Fast response time (≤0.5 seconds) ensures quick adjustments to flow changes, maintaining stable process conditions.
• Leak-Proof Diaphragm Design: Industrial-grade PTFE/EPDM diaphragm (cryogenic-resistant) ensures a tight seal, preventing cryogenic fluid leaks and ensuring safe operation. Diaphragm is resistant to ultra-low temperatures and chemical corrosion from cryogenic media.
• Easy Control Integration: Compatible with 4-20mA signal control systems, allowing for remote monitoring and automatic regulation of cryogenic liquid flow. Can be paired with positioners (optional) for enhanced precision and feedback.

The 2-way globe valve design is specifically optimized for cryogenic liquid regulation, delivering superior throttling performance and flow control:

• 2-Way Flow Regulation: 2-way design (inlet/outlet) provides precise on/off and throttling control, ideal for regulating cryogenic liquid flow in pipelines, storage systems, and industrial processes. Ensures consistent flow rates even at ultra-low temperatures.
• Globe-Style Throttling: Globe valve structure offers excellent flow control characteristics, with a linear flow curve that allows for precise adjustment of cryogenic liquid flow. Perfect for applications that require tight flow control (e.g., LNG regasification, cryogenic cooling processes).
• Minimal Flow Resistance: Optimized valve seat and trim design (stainless steel or Hastelloy) minimizes flow resistance, reducing energy consumption and ensuring efficient cryogenic liquid regulation. Resists wear and corrosion from cryogenic media.

Built with premium cryogenic-resistant materials, this valve is designed to withstand the harsh conditions of cryogenic liquid regulation:

• Valve Body Material: Available in SS304, SS316L, or Hastelloy C276—all cryogenic-resistant, corrosion-resistant, and able to maintain structural integrity at -196℃. SS316L and Hastelloy options are ideal for aggressive cryogenic media (e.g., liquid oxygen, corrosive cryogenic chemicals).
• Valve Trim & Seat: Trim made of stainless steel or Stellite (wear-resistant), with a PTFE or metal seat for a tight, leak-proof seal. Resists galling and wear, ensuring long service life even with frequent operation.
• Safety-Focused Design: Equipped with a blowout-proof stem and anti-static device, preventing stem blowout and static buildup—critical for safe operation with flammable cryogenic liquids (e.g., LNG). Complies with cryogenic safety standards to minimize accident risks.
