500M Velocity Control Trim

Velocity control trim is suitable for compressible and incompressible fluids and provides many advantages that result in improved performance, reduced maintenance and system simplification. This advanced design “velocity control” trim prevents the generation of noise and or cavitation at the source, eliminating the need for supplementary devices such as diffusers and silencers, and the related expense. As implied in the name, the trim is based on velocity control principles. The tortuous fluid path is formed by the number of concentric cages, radial flow paths and the number of axial flow changes along the milled cavities. The cylinders are firmly connected by vacuum brazing, eliminating external leakage, or short circuiting, while permitting sufficient inter-stage clearance flow. As fluid passes through each passage, velocity is “controlled”, followed by a correspondingly “controlled” pressure reduction. For detailed specifications, please refer to the product bulletin 500M.

Series V701 Venturi Seat Angle Valves
1” through 16” ANSI Class 150, 300 and 600

The Series V701 is a single-seated, post-guided, angle valve with a flange-retained outlet, venturi seat ring. Designed to handle difficult services involving erosive fluids, fluids with entraned solids and slurries, this streamlined body and venturi seat ring construction minimize erosion in even the toughest applications. Applications include throttling control or isolation control of liquids, gases, slurries and steam through a wide range of service applications. For detailed specifications, please refer to the product bulletin V701-1.
