Description The 18400 and 78400 Series valve is used in high-pressure liquid service applications to help eliminate cavitation. The 49000 Series features enlarged body galleries to accommodate up to 36-stages of pressure reduction. The 84000 Series SteamForm* valve includes a patented water-injection system for efficient desuperheating in steam conditioning applications. The 71000 Series is a modified sweep-angle valve that can reduce fluid impingement through the body and includes heavy guiding and durable trim parts. The 72000 Series offers precise capacity control while efficiently reducing noise and outlet velocities using single or multiple cages or V-LOG trim.
