The DeFlo VSD integrates the precision and simplicity of a Control Valve into a Desuperheater to attain maximum turn-down, responsiveness and accurate control.
For the maximum efficiency the DeFlo VSD atomizes the cooling fluid at the vena contracta just downstream of the throttling point right at the injection point. The special design of the spray retainer ensures a hollow swirling cone pattern of the atomized fluid.
The total cooling water differential pressure is available at the throttling point hence optimizing the atomizing effect even further.
This combined type Pressure Reducing cum Desuperheating control valve is a compact yet effective and carefully designed device. The MASCOT DeFlo SCV eliminates all common issues faced by combined type steam conditioning valves.
The SCV is the most efficient way of steam conditioning where the water is injected in a highly turbulent area to ensure most efficient water to steam mixing. The DeFlo SCV are available in Standard, Angle and Expanded outlet configuration.
No special expertize is required to operate or maintain the MASCOT DeFlo SCV as it utilizes most spares of a Standard GFlo Globe Control valve with an addition of a Thermal Desuperheating Sleeve at its outlet. This spray method protects the valve belly from pitting and thermal shocks/stresses unlike most competitive designs. This also reduces the SCV maintenance costs as the Valve and Trim life is greatly enhanced.
With an extended knowledge of Control Valves and Desuperheating units MASCOT is one of the only two specialists in the world who are in the field of Pressure Reducing and Desuperheating
