Female Butterfly Handle Ball Valve

Standard PTFE seats are suitable for most water, oil, and gas applications up to 120°C, offering excellent chemical resistance and low friction coefficients. PTFE+20%CF incorporates carbon fiber reinforcement, extending the maximum service temperature to 200°C and providing measurably higher wear resistance under high-cycle or abrasive media conditions. For high-temperature process lines, steam-adjacent systems, or applications with valve cycling frequencies exceeding standard service expectations, PTFE+20%CF is the recommended configuration.

A 1PC body is a single non-separable casting - once internal components wear or fail, the entire valve must be removed from the pipeline and replaced. A 2PC body incorporates a bonnet that can be removed in-line, allowing the ball, stem, seats, and seals to be inspected and replaced without pipe disconnection or system shutdown. In continuously operating systems - data center cooling loops, semiconductor process lines, industrial chemical systems - this translates directly to lower maintenance labor costs, shorter service windows, and extended total valve service life.

Full bore is a functional requirement in four specific scenarios: in-line pigging operations where the pig must pass through the valve unobstructed; flow measurement installations where reduced bore would introduce unacceptable measurement error; systems with strict pressure budget constraints where the additional pressure drop of a reduced bore valve cannot be absorbed; and slurry or solids-carrying media where a reduced bore creates a restriction point for particulate accumulation. For standard on/off isolation in clean fluid systems, reduced bore is often acceptable - but if any of these conditions apply, full bore is the correct specification.

The butterfly handle has a significantly lower lateral clearance profile than a standard lever handle - typically 30 to 40% narrower - making it the correct choice for manifold assemblies, skid-mounted systems, and panel-integrated configurations where center-to-center valve spacing is tight. It delivers identical quarter-turn operation and the same tactile open/closed position indication as a lever handle, with no reduction in operating torque performance.

The 201 SS handle is suitable for indoor industrial environments and applications where the handle material is not subject to corrosive exposure. The 304 SS handle is recommended for outdoor installations subject to weathering and moisture, marine or coastal environments with chloride exposure, projects where material specifications require full 300-series stainless steel compliance, and applications where handle material traceability is required by procurement specification.

CF8/F304 uses standard 304 stainless steel internals and is suitable for most water, oil, and neutral gas applications. CF8M/F316 incorporates molybdenum-alloyed 316 stainless steel, providing significantly improved resistance to chloride-induced corrosion, acidic media, and seawater. For semiconductor chemical distribution, coastal or offshore installations, and any application involving chloride-containing process fluids, CF8M/F316 is the correct specification.

The standard MOQ is 100 pieces per configuration, with a lead time of 7 days for standard sizes and materials. Mixed configurations - for example, combining CF8/F304 and CF8M/F316 within a single order - count toward the total MOQ collectively; please confirm split quantities with our sales team at the time of inquiry.

Yes. Custom sizes beyond the standard ¼" to 2" range are available, with material options in 304 and 316 stainless steel. For OEM requirements, project-specific dimensional tolerances, or non-standard seat material combinations, please contact our engineering team with full technical specifications. Feasibility confirmation is provided within 24 hours of inquiry.
