Cryogenic control valve Mechanism

When closed, cryogenic ball valves contain cryogenic or low-temperature gasses inside storage tanks securely. High-pressure levels come from extremely low temperatures, where cryogenic ball valves are engineered to open to allow the pressure to decrease with open gas flow. Once the pressure drops, the cryogenic valves will again seal the container to avoid more leakage.

Liquid nitrogen ball valve

Cryogenic ball valves are valves that are applied in the management and safe storage of matter at very low temperatures. They are built to withstand temperatures as low as -190°C to absolute zero (-238°F to -460°F ) and are thus also known as low temperature ball valves. They are equally capable of handling extremely high pressures that result from such extreme temperatures.

Designed to withstand cold and harsh industrial conditions, high-pressure cryogenic valves help make the handling, storage, and transportation of liquefied industrial gasses and Liquid Natural Gas safe and straightforward. 

With excellent capacities for high amounts of pressure, the pressure capability of cryo ball valves can go from Class 150 to 2500 or up to 750 psi. Cryogenic ball valves are used in applications that involve temperature ranges from (-40° F) -40° C  as low as -196° C(-321° F). Standard bonnets of these valves can be installed from 15° to 45°.

Cryo ball valves are often used in handling liquid nitrogen, which can be used in various industries like HVAC applications, food storage, and others. Liquid nitrogen ball valves can be placed under temperatures as low as the absolute zero.

Cryogenic ball valve design

A cryogenic ball valve consists of 3 parts: an actuator, a stem, and a ball. The actuator is the outermost part for which we offer a variety of designs. It is connected to the stem which is a rod-like structure that houses the floating ball. When the actuator is turned, the stem also rotates and repositions the ball accordingly.

Cryogenic ball valves feature long stems, more commonly known as bonnets, for them to work safely in the pipeline. The valve’s packing remains warm with the long stem, which prevents leakage. The design also gives plants flexibility in installing jacketing equipment to maintain the optimal temperature. In places where space is not abundant, the extended arm can also allow easy access.

Cryogenic ball valves: Applications

  • Liquid Gas Tanks 

Liquid nitrogen and other cryogenic gases are stored in tightly sealed LNG tanks. The tanks are fitted with ball valves for nitrogen gas to allow the dispensation of liquid gas to other tanks whenever necessary.

  • Power Plants 

Liquefied natural gases are becoming a preferred source of energy. Power plants store them and use cryogenic ball valves to control their transfer through special pipelines.

  • LNG Ships

Specially designed ships with LNG tanks are used to ship cryogenic gases. They are fitted with cryogenic ball valves to load, offload, and maintain the integrity of the gas during transport.

  • Cooling System

Cryogenic ball valves are used to release controlled amounts of LNG to cool high heat scientific operations like Nuclear Magnetic Resonance.
