Designed for long service life, newly designed CV91ís have straightening vanes that reduce turbulence in incoming flow, thus minimizing noise, vibrations,
erosion, cavitations, and other factors that could result in premature valve failure.
Minimal head loss
Head loss is minimized by providing a large cross-sectional area which exceeds that of the adjacent pipeline. Additionally, the spring-loaded, center guided disc is designed with very low cracking pressure which reduces the amount of energy required to open the valve.
Quick closure to reduce water hammer
Silent shut-off is achieved via the fully automatic, spring assisted disc that closes near zero flow velocity. The lightweight, center guided disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum.
Metal-to-metal seats precision machined sealing surfaces allow the CV 91's to maintain a
tight seal that meets or exceeds API 598 leakage requirements. Resilient seats can also be furnished.
