By digesting and absorbing structural styles of world-famous brands such as German HORA, American Fisher and Yarway, our new generation of HTHP variable frequency desuperheating and reducing device is optimally designed by the company and confirmed by users to be a stable, safe and reliable product. Steam reducing valve or steam desuperheating and reducing valve adopts multistage cage grid structure, whose optimally designed valve seat and valve core boast wide regulation range, stable performance and low-noise operation. Its advantages are as follows: 
1. Excellent flow feature adapts to wide-range (10-100%) change of steam load.
2. Balanced type valve core reduces actuator torque.
3. Sealing surface of valve core and valve grid owns bead weld of erosion-resistant Stellite alloy.
4. The lowest leakage rate.
5. Low-noise design.
6. Thanks to optimized superstructure of reducing valve, during repair, it is unnecessary to disassemble the valve body, in order to disassemble and assemble internal components.
