Pressure relief valves have high flow capacity in order to be capable of efficiently directing flow to tanks. They"re used in hydraulic systems, and limit system pressures at specific levels. When a prescribed set pressure limit is reached, a pressure relief valve will immediately respond by sending excess flow from the system back into the tank.

Cleaned and bagged to meet CGA G-4.1 for oxygen service and other high-purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Set pressure is not adjustable.

Valves are not intended for direct contact with cryogenic liquids. Risers (sold separately) are required to convert cryogenic liquids into gases before they contact the valve. 3/8 NPT valve requires a 1/2 NPT × 3/8 NPT bushing when using a riser.

From the most recent Small-Scale LNG systems to the traditional liquefied industrial gases supply, air separation plants, LNG storage, distribution and transportation, aerospace, petrochemical, and medical applications, Habonim cryogenic products offer added values on safety, fugitive emission prevention, reliability, minimal & ease maintenance, space & weight savings, and compatibility to regulations and special needs of end-users, governing bodies, OEM’s, designers, and system builders.

Habonim’s cryogenic valves are subject to the general Habonim valves design, materials, practices, methodologies, and certifications – for more information, see the Valves General chapter in Habonim catalog.

Each cryogenic valve is equipped with a mechanism that prevents pressure buildup in the valve cavity, eliminating the risk that liquefied-gas evaporation will over – pressure the valve body by releasing over-pressured media from the cavity area back to the line.

The Habonim standard bonnet length design complies with BS6364 for non-cold box applications. The long neck bonnet insulates the stem seal from the low temperatures of cryogenic fluids, thus enabling safe and long-lasting seal service. A small gap between the bonnet ID and the stem OD, ensures a thick layer between the media and the stem seal.

The Habonim bonnet design comes in two optional versions. Both are designed to prevent cryogenic liquids from reaching the stem seal. Habonim recommends installation in the vertical position but allows installation at an angle.

A meticulous cleaning and assembly procedure eliminate the ignition hazards that can be caused by the presence of hydrocarbon oil, grease, and metal chips. Habonim uses an environment friendly, alkaline-based degreasing process with controlled parameters. Valves are assembled in a controlled area by personnel who are specially equipped and trained to perform this task. The assembling area, work surfaces, equipment and tools are specially maintained to ensure cleanliness requirements are met.
