Bellows Valves KHWJ80F1.6P & DEH Oil Actuator Servo Valve

Bellows Valves KHWJ80F1.6P & DEH Oil Actuator Servo Valve J761-003A
Product Introduction
The bellows valve (KHWJ80F1.6P) features 1.6MPa pressure resistance, DN80 specification, reliable bellows sealing and strong compatibility. It is matched with the DEH oil actuator servo valve J761-003A for steam turbines, which requires strict control of cleanliness, alignment and calibration. Together, they integrate YOYIK’s industry-leading strength to ensure accurate response and stable operation of steam turbine control systems.
