Cryogenic Valve
Environmentally Friendly LH₂, LNG, LAr, LO₂, LN₂, etc.
MIYAIRI VALVE offers a full lineup of valves for cryogenic facilities.
Miyairi Valve Mfg. Co., Ltd. began by manufacturing valves for Japan’s first domestic Cryogenic tank lorry. Since then, we have expanded our product range to include reliable valves for plant piping systems.
Drawing on years of experience and numerous achievements, our products are designed not only for safety, but also to meet a wide range of needs, including maintaining high airtightness.
