2.Cryogenic Steel Construction for Extreme Low Temperatures

Available in two primary cryogenic material options to match application requirements:

·Austenitic Stainless Steel (1.4301/304, 1.4404/316L): Ideal for ultra-low temperatures down to -196℃, featuring excellent toughness (impact energy ≥27 J at -196℃) and corrosion resistance . 1.4404/316L grade includes 2-3% molybdenum for enhanced chloride pitting resistance, suitable for LNG and marine environments.

·Low-Temperature Carbon Steel (09G2S): For moderate low temperatures (-46℃ to 150℃), cost-effective with tensile strength 390-510 MPa and yield strength ≥245 MPa , compliant with GOST 19904-90 for cryogenic service.

All materials maintain structural integrity and avoid brittle fracture in extreme cold, with austenitic stainless steel offering superior performance in ultra-cold (-100℃ to -196℃) applications such as LNG/LOX handling .

3.GOST Flanged Connections for Secure Sealing

Equipped with GOST 12815/EN 1092-1 Type 11 flanged ends (weld neck), compatible with PN10-PN40 pressure classes and DN15-DN500 size range . Flange sealing face adopts RF (Raised Face) per GOST 28159-99, paired with stainless steel spiral wound gaskets (with graphite filler) for reliable sealing under temperature cycling and low-temperature shrinkage. Flanged design enables easy assembly/disassembly for maintenance, suitable for cryogenic systems where welded connections are impractical.

4.PN10-PN40 (1.0-4.0 MPa) Pressure Rating

Rated for working pressures up to 4.0 MPa (580 psi) at ambient temperature, with pressure-temperature ratings aligned to GOST 12815 and ASME B16.34 .At -196℃ (-320°F), the valve retains full pressure capacity (PN40: 4.0 MPa) for ultra-cold high-pressure applications such as LNG transfer lines. The reinforced valve body (thickened walls per GOST 34294-2017) handles thermal stress from cryogenic media, preventing deformation and leakage during rapid cooling/heating cycles.

5.Integrated Pneumatic Actuator for Precise Control

Equipped with a heavy-duty pneumatic actuator (single-acting/double-acting) designed for cryogenic environments, featuring:

·Control signal: 4-20 mA proportional control (with Tissin TS900 or equivalent positioner) or on-off control

·Action type: Single-acting (fail-safe: NC/ NO) or double-acting

·Operating pressure: 0.4-0.7 MPa (air supply)

·Protection class: IP65/IP67, with low-temperature lubrication (-40℃ compatible)

·Accessories: Limit switch, position indicator (EPI with dry contacts), manual override for emergency operation

The actuator enables precise flow regulation (globe valve linear motion) and remote control, ideal for unattended cryogenic facilities such as LNG terminals and industrial refrigeration systems .

6.Cryogenic-Optimized Design for Reliability

·Extended bonnet: Reduces heat transfer from ambient to low-temperature media, preventing valve stem freezing and packing damage.

·Low-temperature packing: Flexible graphite + PTFE composite packing, resistant to cold brittleness and ensuring stem sealing at -196℃.

·Tight metal-to-metal seal: Valve disc/seat overlay-welded with Stellite 6 alloy (hardness HRC 48-62), wear-resistant and compatible with cryogenic media, meeting GOST 9544 Class A leakage standards .

·Compact structure: Globe valve design with short face-to-face dimensions (per GOST 12820), saving installation space in dense cryogenic piping systems.
