UK stock and 24-hour technical response from Bicester, with global dispatch for international and multi-site projects.
Looking for cryogenic valves for demanding low-temperature service? Valvenok is a UK supplier of precision instrumentation and flow-control solutions for hydrogen, oil & gas, power, petrochemical and wider process industries. With extensive experience in high-pressure and specialist-service environments, Valvenok supports procurement and design teams who need technically compliant cryogenic valve solutions integrated with wider piping, manifold and instrumentation packages.
Send your specification or bill of materials and the engineering team will respond within 24 hours with guidance, options and full technical documentation.
Cryogenic valves are critical wherever media such as LNG, liquid hydrogen, liquid oxygen or liquid nitrogen are handled at extremely low temperatures. In these environments, valve selection, materials and construction must be engineered to manage the demands of cold service — not just the pressure rating on the datasheet.
Low-Temperature Embrittlement
Material selection engineered to resist embrittlement and thermal shock, so the valve stays ductile at the extreme low temperatures of LNG, liquid hydrogen and liquefied gases.
Tight Shut-Off Under Cycling
Seat and closure designs that hold a reliable, bubble-tight shut-off through repeated temperature cycling — not just on the first cold cycle.
Seat & Packing Performance
Packing and seat arrangements specified to accommodate the contraction and expansion of cold service without leak paths opening up as the line cools and warms.
Safe Isolation & ESD
Configurations suited to safe isolation and emergency shutdown duty, where a cryogenic line has to be closed quickly and dependably.
Valvenok operates across high-pressure and specialist-service applications, supplying precision-engineered industrial valves and instrumentation products with material traceability and documentation. That focus makes Valvenok a strategic partner for procurement teams consolidating cryogenic service valves with associated instrumentation, manifolds and connection hardware under a single technical envelope.
Cryogenic systems rarely operate in isolation. They are typically integrated with upstream and downstream instrumentation, isolation and safety components. Valvenok supports this broader system requirement with:
• Instrumentation valves, including needle valves for precise metering and isolation
• Floating ball valve solutions rated up to 10,000 psig for shut-off and diversion
• Uni-directional check valves to prevent backflow in transfer and loading systems
• Relief valve technologies for pressure surge protection in cold-service lines
• 2-, 3- and 5-valve manifolds for transmitter isolation, equalisation and venting
For cryogenic duty, these components can be specified in materials such as SS316, Duplex, Monel or Hastelloy, with NACE MR0175 / MR-01-75 available on request across relevant ranges. This lets procurement and design teams align cryogenic valve selections with compatible instrumentation valves, pipe fittings, tube fittings, filters and air headers that share similar corrosion-resistance and documentation requirements.
"Cryogenic valves are rarely bought alone — they arrive with the instrumentation, manifolds and fittings around them. Sourcing the whole envelope from one documented supply chain is what keeps a cold-service project on schedule."
— Valvenok TeamSelecting the correct pipeline and instrumentation interface is essential when specifying cryogenic valves. Valvenok offers an extensive portfolio of connection products to help build complete, traceable systems around specialist cryogenic equipment, including:
• High-pressure tubing and tube fittings for instrumentation take-offs
• Stainless steel pipe fittings in NPT, BSPP, BSPT and ISO standards
• Precision stainless steel fittings and adaptors for tube-to-pipe transitions
• High-pressure cone & thread fittings and pipe fittings up to 60,000 psi
• Gauge connectors, dielectric unions and specialised connectors for critical infrastructure
This breadth of connection technology allows Valvenok to support cryogenic valve installations with compatible, documented interfaces from valve outlet through to instrumentation and control — including projects that combine cryogenic flow control with hydrogen infrastructure, offshore, subsea or power applications where specialist engineering input and rigorous qualification are required.
Valvenok provides a structured, engineering-led response to enquiries involving cryogenic valves and associated equipment — five clear steps from datasheet to dispatch.
01
Specification Review
You share your datasheet, process conditions, or bill of materials. Valvenok's technical team reviews the pressure, temperature, media, standards and material requirements for the duty.
02
Application & Compatibility Check
The team assesses duty conditions, corrosion considerations, any hydrogen or sour-service requirements, and applicable project standards such as NACE MR0175.
03
Product Recommendation & Sourcing
Valvenok identifies suitable cryogenic valve solutions and matches them with compatible instrumentation, tubing and fittings — recommending a fit rather than sending a catalogue link.
04
Documentation & Traceability
Every order is backed by full technical documentation and material traceability. Where applicable, heat-code traceability and certification are provided to support project and regulatory requirements.
05
Lead Time & Logistics
With UK stock available for a wide range of instrumentation valves, manifolds, fittings and accessories, Valvenok helps compress lead times. Global dispatch supports international projects and multi-site roll-outs.
Valvenok supports UK and international clients from its UK base at Ground Floor, St Edburgs Hall, Priory Road, Bicester, OX26 6BL. From Bicester, the team coordinates UK stock, immediate shipment of instrumentation and industrial valves, and engineering support for cryogenic, hydrogen, oil & gas, petrochemical, power, offshore, subsea and general process applications.
Whether you are developing electrolyser or refuelling infrastructure, LNG import/export facilities, or low-temperature process units, Valvenok can work with your engineering team to align cryogenic valve requirements with compliant instrumentation valves, manifolds, filters, air headers and connection hardware.
Cryogenic valves are designed for very low-temperature service, typically handling liquefied gases such as LNG, liquid hydrogen, nitrogen, oxygen or helium. They provide safe isolation, control and emergency shut-off while managing thermal contraction, tight shut-off and the material embrittlement associated with cryogenic conditions.
Yes. Valvenok offers engineering support to review your process conditions, materials and standards, then helps you identify suitable cryogenic valve solutions and compatible instrumentation, manifolds and connection products. Send a specification or bill of materials and the team will respond within 24 hours with guidance and options.
Yes. Valvenok supports clients in Bicester, across the United Kingdom, and globally. From the Bicester office the team provides technical support, documentation and rapid shipment of associated instrumentation valves, fittings, manifolds and filters that interface with cryogenic valve installations.
In most projects, cryogenic valves are part of a larger system that includes isolation valves, non-return devices, pressure relief and measurement points. Valvenok supplies needle valves, check valves, manifolds, filters and air headers that can be engineered to integrate with cryogenic duty valves and meet project standards for documentation and traceability.
Yes. Valvenok supplies hydrogen product ranges and project support for electrolyser and refuelling infrastructure. Where hydrogen is stored or transferred at low temperatures, the team can align cryogenic valve requirements with hydrogen-compatible instrumentation valves, manifolds and fittings, and advise on materials and standards such as NACE MR0175.
Provide as much detail as possible: media, minimum and maximum temperatures, pressure range, line size, connection type, required standards, materials, and any project-specific documentation or testing requirements. A drawing, datasheet or full bill of materials helps the engineering team respond quickly and accurately.
Valvenok targets a 24-hour response time for specification and bill-of-material enquiries, including those involving cryogenic valves. With UK stock available for a wide range of instrumentation valves, manifolds and fittings, the team can often support compressed project schedules and urgent requirements.
Yes. Valvenok supplies control, instrumentation and API valves, along with manifolds, filters, air headers and a comprehensive range of pipe fittings.
