| High Pressure Let-Down Valve (300 EO) |
| |
| With the growth of plant size, demands for high performance control valve for high /\ P and capacity have been steadily increasing. This type of performance cannot be expected from conventional valves.
The increase in /\ P not only makes the valve noisy, but also results in high velocity and rapid deterioration of the trim, even if they are made of special materials. It is necessary to distribute the pressure drop across various stages. In order to accomplish this, Mazda offers “300 EO” with multiple-cages.6"size 900# alloy steel valve waiting for shipment to Reliance 55 MW power plant at Goa
Each stage of pressure reduction takes place in the Subcritical region and the multiplicity of stages permits large /\ P to be achieved accurately and quietly.
The valve is provided with expanded outlet to control steam exit velocity thereby restricting noise level to 85 dBA. For improved performance, with standard actuator, Mazda provides Pilot Balance Design for rigidity and stability at high pressure drop. |
