Water ball valve 3/4 inch Herkules nut-and-screw with butterfly KMH21

Ball Valve – Reliability and Durability in Every System

This Herkules ball valve, manufactured from high-quality brass, is a robust and universal solution for water and heating systems. Designed to work with both hot and cold water, as well as glycol, it performs reliably in residential installations and demanding industrial applications. Its nut-and-thread design with a butterfly mechanism ensures convenient installation and easy operation.

This valve stands out primarily for its high resistance to corrosion and mechanical damage. The brass grade CuZn40Pb2 (CW617N) guarantees long-term operation even under harsh conditions. Additionally, PTFE (Teflon) seals ensure tightness and minimize the risk of leaks. The full-bore valve design further enhances medium flow efficiency.

Construction and Applications

The valve features a 3/4" connection on both sides: a cylindrical internal gas thread (BSPP-G, ISO 228-1) on one side and a cylindrical external gas thread (BSPP) on the other. With a pressure class of PN 40, the valve is rated for operation at a maximum pressure of 40 bar, making it suitable for installations with elevated safety requirements.

The Herkules valve is ideal for use in:

• Water supply systems
• Central heating systems
• Compressed air installations
• Glycol systems (50% glycol + 50% water solution)
• Residential and industrial construction
