Product Q&A
Q:What is the working principle of this valve?
A:
Water enters the main valve control room through a micro filter, needle valve, and one-way valve. Since the needle valve opening is smaller than the ball valve, drainage is faster than intake, reducing pressure and opening the main valve disc.

A:
No, it uses hydraulic self-control and does not need other devices or energy sources to function.
Q:What are the available pressure ratings?
A:
The valve is available in PN10, PN16, and PN25 pressure ratings according to EN 1092 standards.
