    Description

    The 49000 Series V-LOG high pressure drop valve features an enlarged body gallery to accommodate gas expansion and up to 36 stages of pressure reduction via a stacked disk trim design. It offers optimized severe service solutions for high-pressure drop applications with potential damaging noise or cavitating fluid conditions. Built around the Masoneilan V-LOG Energy Management Trim, the 49000 Series is capable of handling a wide range of both liquid and gas services in a variety of process industries.

    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
