High Quality Cryogenic Ball ValvesHigh-Quality Cryogenic Ball Valves are valves for controlling cryogenic liquids and gases, suitable for liquid nitrogen, liquid helium, LNG, and LPG, available in bulk and customizable.read more
Introduction
A Cryogenic Ball Valve is a specialized ball valve designed to operate safely and reliably at extremely low temperatures, typically below –40 °C and down to –196 °C. It is mainly used to control liquefied gases in cryogenic service.

Features of Cryogenic Ball Valve
-
Extended Bonnet Design
The valve is equipped with an extended bonnet to keep the stem packing and sealing area away from cryogenic temperatures.
-
Pressure Relief (Vented Ball) Design
A pressure relief hole in the ball allows trapped liquid to vaporize safely.
-
Anti-Static Device
An anti-static mechanism ensures electrical continuity between the ball, stem, and body.
-
Low Operating Torque
Precision-machined ball and seats reduce friction.
Customization Options
Temperature and Media Adaptation
Valves can be customized for specific operating temperatures, from –40 °C to –196 °C, and for different cryogenic media such as LNG, liquid nitrogen, or liquid oxygen.
Body and Bonnet Materials
Materials can be selected based on low-temperature impact requirements: stainless steel (CF8/CF8M, F304/F316) or low-temperature carbon steel (LTCS).
Seat and Seal Materials
Seats can be made of PTFE, modified PTFE, or PCTFE, and a soft-to-metal backup seal can be added for fire-safe applications.
Extended Bonnet Length
The extended bonnet can be tailored to installation needs, typically 250–600 mm, to keep the packing in the ambient temperature zone and prevent freezing.
Ball Design and Pressure Relief
Floating or vented balls are available to relieve pressure in the valve cavity.
Operation and Actuator Interface
Valves can be configured for manual, pneumatic, or electric operation. ISO 5211 mounting pads are provided for actuator compatibility, and torque data can be supplied.
