Stainless Steel Instrumentation Ball Valve with Lever Handle

The Q21F-64P series instrumentation ball valve is designed to deliver reliable on-off flow control within compact gas supply and high-pressure fluid networks. Available in both robust square block and sleek cylindrical bar-stock body styles, it utilizes high-grade 304 stainless steel for superior oxidation and chemical resistance. Equipped with extended weldable pipe stubs and a heavy-duty vinyl-insulated or solid metallic lever handle, it provides low-torque, fast-acting isolation for critical industrial pipelines.
