NJH Ultra-High-Temperature Globe Valve (-196℃～+600℃/100bar)

NJH Stainless Steel Flanged Globe Valve (DN15～40mm)

Uses
NJH globe valve is used for flow adjustment and the safe shutoff of high temperature pipelines. The valve stem employs a dual-seal packing structure, ensuring reliable performance at 600℃ temperature with fire-resistance and positive shut-off. NJH is applicable to air, steam, molten salt and other non-flammable gases, heat transfer oil and other liquids.
