Product Description
ULTIMATED HIGH PRESSURE DESIGN
The cage guided single seat control valve is used for high pressure and high temperature working condition of steam and water purpose. It is assembled with pressure sealed forged body and trim of anti-cavitation design, processed with high grade alloy steel, which offers the effective solution to high pressure drop conditions. The cooperation between cage and trim ensures the more accurate adjusting performance and very tight sealing under extreme steam conditions.

FEATURES
RADIATOR DEIGN | For high temperature purpose, the radiator strcuture will be applied to suit high temperature conditions, the radaitor will help to disperse heating and protect the actuator form overheating circumstances so as to ensure the stability of actuator. |
HIGH PERFORMANCE SPRING | Only high grade material is selected for operation for control valve, the trim mwterial has been gone through strictly test including physical and chemical analysis so as to ensure the best stablity and safety for operation. |
VERY TIGHT SHUT OFF | The Seat surface is treated with hard stellite faced, the import sealing ring with motive seal purpose is adopted, ensure the a very tight shut off. |
PRESSURE SEAL BONNET | 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. |
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. |
