Hy-Lok USA, Inc. supplies premium CRYON trunnion ball valves, needle valves, and tube fittings for use in cryogenic and marine applications including beverage carbonation systems and analytical instrumentation.

CryogenicsValves and fittings are made from brass or stainless steel and fire tested to AP 607/6FA and BS 6755 Part2 standards. We manufacture a popular line of standard valves, but also have the capability to produce custom cryogenic valves to customer specifications. We carry stock on many standard components for off the shelf convenience to our customers.

Hy-Lok USA is proud to provide solutions for cryogenic applications. These products are designed for operation at extremely low temperatures. Cryogenic equipment, especially pressure vessels and piping components such as those we provide, is typically involved in transporting supercooled liquids, including nitrogen, argon, oxygen, and liquid helium.

The most crucial element in the effectiveness of cryogenic components is proper insulation. This ensures the proper maintenance of temperature levels within the equipment. Proper insulation also protects equipment from extreme temperatures and hazardous materials during handling.

Hy-Lok USA’s cryogenic products include CRYON valves, trunnion ball valves, needle valves, and tube fittings. They are used in applications such as cryogenic valves and vessels, analytical instrumentation, and beverage carbonation systems. Our products are widely used in the cryogenics and marine service industries.

We carry many U.S. and international certifications including ISO 9001, 14001, OSHAS 18001, ASME, API, and PVD accreditations in quality, safety, and environmental protection. We use the highest quality raw materials and can provide full material traceability reports. These rigorous quality standards are part of our commitment to reliability and customer service. Our efficient manufacturing and management systems allow us to provide customers with this premium level of quality and service at prices much lower than competitors.
