Structural features:
A. Body/Bonnet: Forged structure;
B. Angle type structure:
Horizontal inlet, vertical outlet
C. Seat: removable, easy to repair;
Material: NO7718:anti-corrosion, anti-washout
Integral precipitation hardening treatment: solid solution + aging Reliable sealing, high hardness, HRC ≥42 Anti-scouring, long service life;
D. Spring-loaded self-adjusting nozzle assembly.
The nozzle assembly consists of nozzle, spray rod, spring, nut, shell, spray rod in the spring and the media force under the action of the flow of how much to automatically adjust the degree of opening, to maintain the spray water at least 0.3MPa differential pressure, to ensure that the desuperheated water in the variable operating conditions always maintain a good atomization effect.

E. Valve stem (integrated with disc): Integral forging;
A) sealing surface HRC ≥42.
B) Integral precipitation hardening treatment;
F. Multi-stage throttling and noise reduction orifice plate;
a) Designed with a one-stage pressure reduction window with equal percentage flow characteristics.
b) Equipped with two-stage throttling noise reduction orifice plate; reduce the vibration and noise of the valve;
G. The outlet is equipped with a protective casing: to prevent cracks in the outlet pipe.
