The Q647F-16P is a complete, pre-assembled pneumatic ball
valve package designed for rapid automatic on/off isolation in
industrial pipeline systems. The assembly integrates four
purpose-matched components: a 2-piece full-bore SS316L
flanged ball valve, an aluminium rack-and-pinion pneumatic
actuator, a limit switch box with dual micro-switches and visual
open/close indication, and an inline filter-regulator unit with
integrated pressure gauge.

Why Specify This Valve from Bautu
Rapid Quarter-Turn Pneumatic Operation
Driven by compressed air at 0.4–0.8 MPa, the actuator delivers quarter-turn operation typically in under 5 seconds — significantly faster than electric actuators — making it ideal for emergency shut-off, high-cycle automation, and process control applications. Available in double-acting (DA) for maximum torque or spring-return (SR) for inherent fail safe closure or opening on air loss.
SS316L Corrosion Resistance + Class VI Sealing
The SS316L valve body offers outstanding corrosion resistance across aggressive chemical, marine, and process environments. PTFE seats deliver bubble-tight shut-off to ANSI Class VI. The limit switch box provides real-time open/close feedback to PLC, DCS, or SCADA systems via SPDT micro-switches rated up to AC 250V / 5A. Delivered pre-assembled, pressure-tested, and ready for immediate installation.

Frequently Asked Questions
What is a Pneumatic SS316L Flanged Ball Valve?
A pneumatic SS316L flanged ball valve is a quarter-turn automated valve with a body, ball, and stem manufactured entirely from 316L stainless steel, driven by a compressed-air actuator for remote or automated operation. It provides reliable on/off flow control in corrosive, high-purity, and hygienic pipeline systems without manual intervention. Bautu's pneumatic SS316L flanged ball valves are available in double-acting and spring-return (fail-safe) configurations, with optional solenoid valves, limit switches, and ATEX-rated components for hazardous area installations, covering flange standards including ANSI, DIN, and JIS.
What is the difference between SS316L and SS316, and why does it matter?
SS316L is the low-carbon variant of SS316, with a maximum carbon content of 0.03% versus 0.08% in standard 316. This lower carbon content is critical in two situations: first, it eliminates sensitization — a phenomenon where carbon migrates to grain boundaries during welding, forming chromium carbides that drastically reduce corrosion resistance in the heat-affected zone. Second, it is mandatory in applications governed by ASME, FDA, and pharmaceutical GMP standards that require full corrosion resistance in welded assemblies. SS316L is the standard material for pharmaceutical manufacturing, food processing, semiconductor fabrication, and marine chemical systems where weld integrity and long-term corrosion resistance cannot be compromised. All wetted parts in Bautu's SS316L valves — body, ball, stem, and seat retainer — use certified 316L material with material test reports (MTR) available upon request.
What is the standard lead time, and can Bautu supply complete actuator assemblies?
Standard pneumatic SS316L flanged ball valves are delivered in 3–5 weeks from order confirmation, including actuator mounting, air connection, and factory operational testing. Bautu supplies fully assembled packages with solenoid valves (24VDC / 110VAC / 220VAC), limit switch boxes for position feedback, and positioners for modulating control. ATEX / IECEx certified actuator components are available for Zone 1 and Zone 2 hazardous area classifications.
