Gaoshan Valve – J41H(Y) Globe Valve
Model Series: J41H-16(Q)/16C/25Q/25/40/63/100 / J41Y-160I | Pressure Class: PN16~PN160 | Size Range: DN20~DN300
J41H(Y) series globe valves are straight-through flanged stop valves designed for water, steam, and oil systems. With a variety of body materials (cast iron, ductile iron, carbon steel, chrome-molybdenum steel), they meet different pressure and temperature requirements from PN16 to PN160.
✅ Core Strengths
- Multi-Material Options: Available in cast iron, ductile iron, carbon steel (WCB), and chrome-molybdenum steel for different working conditions.
- Wide Pressure/Temperature Range: Rated PN16 to PN160, with max working temperature up to 550℃ for high-grade materials.
- Durable Sealing: 2Cr13 stainless steel or hard alloy sealing surfaces for tight shut-off and long service life.
- Flexible Packing System: Flexible graphite packing ensures reliable sealing and easy maintenance.
