Advantages

The Masoneilan 49000 Series V-LOG high pressure drop valve is designed with an expanded body gallery to facilitate gas expansion and offers up to 36 stages of pressure reduction through a stacked disk trim configuration. This valve provides optimized solutions for severe service applications characterized by high-pressure drops, which may lead to damaging noise or cavitating fluid conditions. Constructed around the Masoneilan V-LOG Energy Management Trim, the 49000 Series is adept at managing a diverse array of liquid and gas services across various process industries.

• The advantages of the Masoneilan 49000 Series V-LOG high pressure drop valve include:
• The cast globe-style body of the Masoneilan 49000 Series is lighter and more compact than forged or fabricated alternatives, contributing to lower installation costs.
• The enlarged body galleries and expanded outlets facilitate velocity control for gases undergoing expansion.
• Galleries are designed to accommodate standard V-LOG trim dimensions, ensuring a uniform body platform and an optimized solution.
• The V-LOG trim is suitable for both compressible and incompressible fluids in severe service environments.
• The V-LOG and Lo-dB trims minimize noise and cavitation, protecting the valve and adjacent equipment from potential damage.

The V-LOG Trim can be tailored for use with either compressible or incompressible fluids in demanding service conditions, making the Masoneilan 49000 Series valve an excellent option for various liquid and gas applications, including:

• Boiler feed water start-up and regulation
• Steam letdown
• Pump discharge
• Water reinjection
• Gas recycling
