Benefits
|
Angle Design
|
Reduces turbulence and pressure drop in high-velocity flows, minimizing wear and extending valve life.
|
Forged Alloy Construction
|
Premium materials (e.g., 316Lmod, 25Cr duplex, Alloy 20) resist corrosion from urea intermediates (ammonium carbamate) and ethylene peroxide.
|
Sealing Technology
|
Metal-to-metal seats with Stellite® hardfacing ensure bubble-tight shutoff under cyclic pressure/temperature conditions.
|
Integral Bonnet Design
|
Eliminates potential leak paths at the bonnet joint, critical for containing toxic/corrosive media (e.g., ammonia, acetic acid).
|
Anti-Cavitation Trim
|
Optional trim designs prevent cavitation damage in high-pressure drop scenarios, ensuring stable flow control.
