Description
DKV J41W Flanged Globe Valve is a high-performance valve made from stainless steel 304 or 316, designed for industrial pipelines requiring excellent corrosion resistance and leak-proof reliability. Featuring flanged connections (DN50–DN300), it operates efficiently under pressures up to PN40 and temperatures from -29°C to 200°C.
The dual-seal system combining a PTFE gasket and metal seat ensures zero leakage and long-term durability in steam, oil, gas, and chemical applications, making it an ideal choice for demanding industrial environments.
