Globe Valve - Cryogenic Valve | Neway

Cryogenic Globe Valve Globe Neway

Globe valve for cryogenic liquid or gas lines, featuring a stainless steel body and RF, BW, or RTJ ends. Product page specifies a range of 1/2"–42" / DN15–DN1050 and ASME Class 150–2500. The technical brochure for cast steel cryogenic globe indicates a specific range of 2"–28", Class 150–2500, temperature -196°C to 400°C, and manual, pneumatic, or hydraulic operation.

Construction Features

• Extended bonnet and stuffing box to keep packing away from cryogenic zone.
• PCTFE shaft sleeve / bushing for stem stabilization at low temperatures.
• Integrated seat for cryogenic globe execution.
• Sealing surfaces with Stellite hardfacing.
• Drip plate to prevent condensate entry into insulation.
• Cold-extruded stem sealing area for smoother sealing surface.

Applications

Suitable for LNG, LIN, LOX, LAR, cold boxes, air separation units, cryogenic storage, loading/unloading skids, and insulated process lines. Use in oxygen service requires confirmation of cleaning, degreasing, and non-metallic material compatibility.

Selection Criteria

Selection should be based on:

• Minimum design temperature: -50 to -110°C or -110 to -196°C
• Pressure class and end type RF/BW/RTJ
• Operating medium and oxygen cleanliness requirement
• Allowable seat and stem packing leakage
• Manual or actuator operation capability
• Available installation height due to extended bonnet

Certifications

Brochure lists ISO 9001, API 6A, API 6D, CE/PED, TA-Luft, ABS, AD2000, and Fire Safe approvals as available certifications/approvals for the Neway series.

FAQ

Why is an extended bonnet needed?

To keep the packing in a warmer area and limit stem freezing.

Is it a control valve?

Primary use is isolation. Limited throttling requires control of Δp, flow velocity, and potential seat/disc wear.
