Dresser Masoneilan 77000 Series Valve Provides Unique Solution for Environmentally Conscious Energy Delivery Systems

Control Valve Enables Stringent Environmental Standard Compliance
and Optimum Efficiency for Advanced Applications

HOUSTON (May 27, 2010) – The Dresser Masoneilan® 77000 Series is a unique multi-stage expanding area control valve that offers customers one of the most advanced solutions available for advanced energy delivery systems.

The 77000 Series is ideal for high-pressure, high-temperature liquid and compressible fluid control that effectively minimizes erosion, vibrations and high noise conditions. Stable control and durable service life also minimize field maintenance, saving replacement and repair costs.

“The 77000 Series is ideal for technologically advanced refineries that are implementing hydro-processing units and are looking for assistance in addressing green initiatives in their business,” said Chris Bittner, director of engineering for the Flow Technologies segment of Dresser Inc. “This valve enables our customers to recover and refine gas-oils, heavy-residuals, and bottoms while saving on replacement and repair costs.”

The 77000 Series valve solves critical fluid flow applications while providing additional environmental benefits including:

Maximum Efficiency – Enables users to employ the latest technology in energy efficiency by pushing pressures and temperatures to their practical limits.
Minimum Pollutants – addresses critical applications in advanced power plants that serve to minimize fuel consumption and resulting combustion-based effluents, including green house gases.
OSHA Noise Compliance –Manages high pressure drop applications while maintaining OSHA environmental noise attenuation compliance.
Minimum Leakage – Offers ANSI/FCI 70-2 Class V shutoff that ensures minimum unintended fluid loss and contributes to maximum energy efficiency of the system.
Minimum Fugitive Emissions – Offers several design configurations for tight fugitive emissions regulations, including packing designs qualified to ISO 15848.
Advanced Processes – Performs when refining processes for high-grade environmental fuels require a combination of high pressure letdown with cavitation prevention, passing of entrained solids and handling of a multi-phase flow.
