Masoneilan 49000 Series V-LOG™ Low-Noise Anti-Cavitation Valve

Benefits of the 49000 Series V-LOG high pressure drop valve include:
• Compared to forged or fabricated bodies, the cast globe-style body of the 49000 Series offers lower in weight and overall dimensions which helps reduce installation costs.
• Enlarged body galleries and expanded outlets provide velocity control for expanding gases.
• Galleries sized to accept "typical" V-LOG trim dimensions for a standardized body platform and an optimized solution.
• V-LOG trim for use with either compressible or incompressible fluids under severe service conditions.
• V-LOG and Lo-dB trim provide reduced noise and cavitation that could negatively affect the valve and/or surrounding equipment.
The V-LOG Trim can be configured for use with either compressible or incompressible fluids under severe service conditions making the 49000 Series valve a superior choice for liquid and gas applications including:
• Boiler feed water start-up and control
• Steam letdown
• Pump discharge
• Water reinjection
• Gas recycle
