Product Description

Hanno Valve has been manufacturing GOST gate valve castings for over 25 years, covering PN16 to PN250, DN50 to DN400, and various materials like 20L, 15CrMo, 904L, and more. Produced according to GOST 5762, with dimensions following GOST 3706 and GOST 33259, these valves are available with flange or butt-welded connections and manual, electric, pneumatic, or bevel gear operation. Designed with a stem axis perpendicular to the sealing surface, the J41W series ensures reliable shut-off with minimal wear, easy maintenance, and suitability for cutoff, adjustment, and throttling. However, due to flow direction changes, its resistance is higher than other valve types.

Product Key Features:

1. GOST gate valve casting can effectively removes sand through vibration, ensuring high strength, minimal gas emissions, and low expansion.

2. Good fluidity results in castings with a smooth and refined surface finish.

3. Maintains structural integrity without delamination, offering superior thermal stability, efficient heat conduction, and a seamless casting surface.

4. GOST gate valve casting withstands high temperatures while maintaining exceptional strength, low expansion, easy demolding, and strong resistance to sand adhesion.

5. Ensures a uniform shell layer without separation, coupled with rapid curing for efficient production.
