A Wide Array Of Valves

Manual Oxygen Globe Valve, Safe & Precise Flow Control for Oxygen Service

The manual oxygen shut-off valve is a core flow control device specifically designed for oxygen delivery systems. Focusing on "oxygen safety compliance + precise manual control," it addresses the safety concerns of oxygen's flammability, high pressure, and leak-prone nature through deoxidized materials, a grease-free structure, and a reliable sealing design. It is widely used in industrial oxygen production, medical oxygen supply, metallurgy, and other fields requiring the highest levels of oxygen delivery safety. Its manual operation mode eliminates the need for external power, allowing for quick response in emergency situations, making it a critical component of the oxygen system's "safety defense line."

DELCO Top and Bottom Discharge Valve, Reactor Bottom Y-Type Manual Globe Valve

The top and bottom expanding discharge valve (Y-type globe valve for reactor bottom) is a special valve designed for discharging materials from the bottom of reactors, storage tanks, and other containers. It combines the advantages of a "top-and-bottom expanding double-acting valve core + Y-shaped flow channel" structure, effectively addressing the three major problems of "material blockage, residue, and sealing failure" at the bottom of reactors. It is widely used in chemical, pharmaceutical, food, and other industries for handling viscous, particulate, and crystalline media.
