Product Introduction
This Autorun BTS Scotch Yoke double-acting pneumatic butterfly valve is built for the operators who need their valves to show up every day, no excuses. We didn't over-engineer it with fancy features no one will use-we focused on the parts that actually keep lines running.
The body is ductile iron, coated in a tough red epoxy that stands up to the kind of moisture and grime common in water treatment plants and HVAC systems. The full EPDM seat we use isn't just a "standard option"-it's the same one we've tested through thousands of cycles, holding bidirectional shutoff at PN16 (16 bar) from -20°C to 120°C without leaking. The disc is carbon steel, and the flanges are drilled for both PN16 and Class 150, so it drops right into most standard piping without custom work.
The Scotch Yoke double-acting actuator is sized specifically for each DN, not just a one-size-fits-all unit bolted on. The self-lubricating bearings mean you won't be out there greasing it every few months, which we know is a big win for maintenance teams short on time. You can pair it with basic solenoids, limit switches, or positioners if you need remote monitoring-no complicated setup required.
We've put these valves in hundreds of facilities where downtime costs real money, and the feedback is always the same: they just work. No fancy promises, no exaggerated specs, just consistent performance that lets you focus on the rest of the line. This isn't the flashiest valve on the market-but it's the one that won't let you down when you need it most.
