Buy GJ41X GJ641X Plug Valve PN0.6/1.0 Cast Iron Flange End Handwheel/Pneumatic Control
The GJ41X/GJ641X Jacketed Plug Valve by VALVEHU is a premium industrial solution designed for applications involving media that require insulation or heat retention, especially in chemical processing industries. Engineered with precision, this valve supports pressure ratings of PN 0.6/1.0 MPa, making it suitable for both light and medium-duty flow control tasks. Its flanged connection ensures easy integration in pipeline systems, and the jacketed body offers superior thermal management for viscous or temperature-sensitive fluids.
This plug valve is available in two operational modes: the manual handwheel-operated GJ41X and the pneumatically actuated GJ641X, both crafted to deliver tight shut-off and reliable service in corrosive and non-corrosive environments. The body material is offered in cast iron and cast steel, providing mechanical strength and corrosion resistance under normal temperature conditions. The internal sealing elements use rubber-lined sleeves and corrosion-resistant metals, contributing to longevity and leak-tight performance.
The design follows industry-standard dimensions for DN sizes ranging from 25 to 500 mm, ensuring compatibility with common piping configurations. The valve’s compact structure and jacketed construction make it ideal for fluid media that must be maintained above ambient temperatures.
Whether you’re dealing with heat-sensitive materials or require reliable isolation in processing lines, this jacketed plug valve stands out for its durability, thermal efficiency, and operational flexibility.
