IRELAND 160800 Cryogenic Globe Valve with Extended Bonnet and Threaded Nut-Type Cap

Overview

The IRELAND 160800 Cryogenic Globe Valve is an engineered solution for precise flow control of liquefied gases and low-temperature process media in demanding industrial environments. Designed on the principle of linear motion throttling, this globe valve utilizes a guided plug-and-seat geometry to deliver high shutoff integrity and repeatable flow characteristics under cryogenic thermal gradients. Its extended bonnet configuration—constructed from ASTM A182 F304L stainless steel—creates a thermally insulated column between the valve body and actuation interface, effectively minimizing heat ingress into the packing region and preserving seal performance at temperatures as low as –220 °C. The valve complies with EN 1515-1 for flanged connections and meets ISO 5208 leakage class VI requirements for bubble-tight closure when tested with air or nitrogen at ambient temperature, ensuring reliability across air separation units (ASUs), LNG transfer systems, hydrogen infrastructure, and specialty chemical processing.

Key Features

• Extended low-temperature bonnet with integral stainless steel extension sleeve, reducing thermal bridging and maintaining packing integrity at cryogenic service temperatures
• Monolithic seat design machined directly into the ASTM A351 CF3M (304L) body, eliminating potential leak paths and enhancing long-term sealing stability
• Reusable soft-seal disc assembly certified to ISO 5208 Class VI for zero visible leakage during pressure testing
• Full-port trim option available for reduced pressure drop; optional throttling or metal-seated trims support high-cycle or abrasive service
• Robust stem-to-bonnet interface featuring dual O-ring packing with optional enhanced graphite-filled PTFE or flexible graphite packing systems
• Compliance-ready configurations including fire-safe design (per API RP 520 and ISO 10497), copper-free construction (ASTM B16.34 Annex D), and ASME B16.34-rated pressure containment

Sample Compatibility & Compliance

The 160800 valve is qualified for use with liquid nitrogen (LN₂), liquid oxygen (LOX), liquid argon (LAR), hydrogen (H₂), helium (He), and other non-corrosive cryogenic fluids commonly encountered in ASU cold boxes, pipeline transfer stations, and mobile cryogenic transport systems. It conforms to material traceability requirements per EN 10204 3.1 and supports full documentation packages compliant with PED 2014/68/EU, AD 2000-Merkblatt W2, and ASME Section VIII Div. 1. All weld-end variants are supplied with PWHT records and NDE reports (100% RT or UT per ASME B31.3). For GMP-regulated pharmaceutical or biotech applications, optional electropolished internal surfaces (Ra ≤ 0.4 µm) and cleanroom-compatible packaging are available upon request.

Software & Data Management

As a manually operated mechanical device, the 160800 valve does not incorporate embedded electronics or firmware. However, its design integrates seamlessly into digital asset management workflows: each unit carries a permanent laser-engraved serial number linked to a manufacturer’s certificate of conformance (CoC), material test reports (MTRs), and dimensional inspection records. When paired with pneumatic or electric actuators (e.g., IRELAND VA-200 series), the valve supports analog (4–20 mA) and digital (HART, Foundation Fieldbus) communication protocols. Actuated versions include audit-trail-capable position feedback and comply with FDA 21 CFR Part 11 requirements when deployed within validated process control systems meeting ISA-88 and ISA-95 frameworks.

Applications

• Air Separation Plants: Isolation and regulation of liquid product streams (O₂, N₂, Ar) in cold box manifolds and distillation column reflux lines
• LNG & Hydrogen Infrastructure: Emergency shutdown and feed control in liquefaction, storage, and vaporization skids operating below –162 °C
• Chemical & Petrochemical Processing: Handling of low-boiling solvents (e.g., ethylene, propylene) in refrigerated reaction loops and fractionation columns
• Pharmaceutical Cryogenics: Controlled delivery of liquid nitrogen for lyophilization chamber cooling and sterile gas purging
• Hazardous Material Transport: On-board isolation valves for ISO tank containers and cryogenic road/rail tankers compliant with ADR/RID regulations

FAQ

What is the maximum allowable working pressure at –196 °C?
At –196 °C (liquid nitrogen temperature), the maximum allowable pressure is derated to PN40 per EN 1092-1 Table 7 for CF3M material, based on ASME B16.34 stress-temperature ratings.
Can this valve be supplied with SIL-rated actuation?
Yes—when equipped with IRELAND-certified fail-safe pneumatic actuators and positioners, the complete assembly can achieve SIL 2 per IEC 61508 when integrated into a certified safety instrumented system (SIS).
Is hydrostatic testing performed on every unit?
Yes—each valve undergoes shell test (1.5 × PN) and seat test (1.1 × PN) with water or nitrogen per ISO 5208, with test certificates issued for traceability.
Does the extended bonnet require special insulation during installation?
No—thermal performance is inherent to the extended sleeve geometry; however, external insulation may be applied per project specifications to minimize ambient condensation or frost formation.
Are replacement soft seats available as spare parts?
Yes—original equipment manufacturer (OEM) soft seat kits, including fluorocarbon elastomer (FFKM) and PCTFE variants, are stocked globally and supplied with full MTRs and dimensional verification reports.
