Keep large-volume liquids and gases flowing exactly where they need to go with the DN250 PN16 Bray Resilient Seated Lined Butterfly Valve. Built for demanding industrial piping systems, this valve delivers reliable isolation and flow regulation, even under pressures of up to 16 bar.The soft elastomer liner, available in EPDM or NBR, presses firmly against the disc to create a secure, bubble-tight seal. This means fewer leaks, less downtime, and greater confidence in your system's integrity, whether you're managing water treatment lines or complex marine piping.
With threaded bolt holes on both sides of the body, this lugged valve bolts directly into pipe flanges, supporting dead-end service and allowing for downstream piping removal without depressurising the rest of the system. That means maintenance teams can work on one section of pipework while the rest of the line stays operational, saving time and reducing disruption.Operating a valve of this size shouldn't be a workout. The manual handwheel, paired with a gearbox, reduces the physical effort needed to open or close the 250mm disc, giving operators precise, reliable control without straining to turn a heavy mechanism.

Summary: 

• DN250 PN16 Bray Resilient Seated Lined Butterfly Valve with Lugged Body and Gearbox is used to isolate or regulate the flow of liquids and gases in large industrial piping systems at pressures up to 16 bar
• A diameter size of 250 millimeters (10 inches), built for large-volume fluid transport
• Rated to withstand a nominal pressure of up to 16 bar (about 232 psi) under standard operating conditions
• Features a soft elastomer liner (such as EPDM or NBR) that the disc presses tightly against to ensure a secure, bubble-tight shut-off
• The valve body has threaded bolt holes (lugs) on both sides. This allows it to be bolted directly into a pipe flange and enables dead-end service or downstream piping removal without losing system pressure on the other side

A manual handwheel operator that uses gears to reduce the physical effort needed to turn the large 250mm valve disc open or closed
