| HIGHLIGHTS TECHNOLOGY |
 | Radiator Structure Design To suit high temperature conditions, the valve applys with radiator disc structure, such construction will help to disperse the heating effectively and protect the actuator from overheating circumstance so as to ensure the stable operation of all system. |
 | Pressure Seal Construction Pressure seal construction is adopted for body-bonnet joints, seals performance improves as the internal pressure in the valve increases, maintains tightness regardless of thermal transients. |
 | Multi-Stage Piston Design Multi-stage piston trim design gives rapid start-up and shut off capacity, the piston is guided in two areas, with long guiding surfaces and not subject to distortion. |
 | Very Tight shut-off The Seat surface is treated with hard stellite faced, the import |
 | Multihole Cage Design The Multihole cage guided trim is capable of managing large pressure drops and reduces the negative effects of erosion, cavitation, and noise. With the different working condition, the cage can be custom-designed with flow characteristic including of equal-percentage and linear to obtain the highest accuracy of desired steam pressure. |
| COMBINED AS PRESSURE REDUCING DESUPERHEATER SYSYEM |
Y945/645Y pressure reducing valve can be used independently, or it can be assembled as main part of pressure reducing desuperheater for pressure reduction which gives higher performance under critical working conditions.
