Features

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.
