JH 1/2"–2" Desuperheating Water Regulating Valve – Class 150–2500, Precision Flow Control

The JH Desuperheating Water Regulating Valve is a compact high-performance control valve engineered for precise regulation of water flow in desuperheating systems. Designed in accordance with GB/T 4213-2008 and GB/T 17213, this valve comes in sizes from 1/2" to 2" (DN15–50) and supports pressure ratings up to Class 2500 (PN420). The valve features an optimized internal flow channel that enables high Cv (flow coefficient) and low pressure drop, making it ideal for finely tuned cooling water injection. Its high-accuracy valve core provides excellent control over flow characteristics and ensures minimal leakage, supporting both efficient steam temperature regulation and system stability. This valve is well-suited for thermal power plants, steam conditioning stations, and other critical high-pressure, high-temperature steam systems.
