Water ball valve 1/2 inch Herkules nut-and-screw type with butterfly KMH11

Ball Valve – Reliability and Durability in Your Installation

This Herkules ball valve with a 1/2-inch diameter is a robust solution for controlling water flow in plumbing, central heating, and compressed air systems. Manufactured from high-quality brass (CuZn40Pb2 – CW617N), it ensures long-term, trouble-free operation. Its threaded-screw design with BSPP-G (internal) and BSPP (external) threads simplifies installation and guarantees seal integrity.

This valve is particularly valued for its versatility – it performs excellently in both residential and demanding industrial applications. Thanks to its resistance to glycol (50% solution), it is suitable for underfloor heating systems.

Construction and Key Features

The valve’s design has been meticulously engineered for maximum reliability. The brass ball, chrome-plated and polished, ensures smooth opening and closing while minimizing corrosion risk. The ball and stem seals are made of PTFE teflon, guaranteeing leak-tightness and resistance to mechanical damage. Additionally, the valve features an adjustment screw that compensates for stem play, extending the device’s service life.

Pay attention to the reinforced valve body and double stem sealing, which significantly enhance pressure resistance (PN 40, i.e., 40 bar) and operating temperature tolerance (up to 140°C). The full-bore design eliminates pressure loss and ensures optimal medium flow. The threaded connections, with a high number of threads, guarantee secure and leak-proof assembly.

Applications and Benefits

The Herkules KMH11 valve is the ideal choice for:

• Installers: Quick installation thanks to standard threads, reliable performance, and long-lasting durability save time and reduce repair costs.
• End Users: Enhanced safety due to high-quality materials and robust construction, dependable operation over many years, compatibility with various media (water, glycol, air).
• Heating Systems: Designed for glycol use, making it the perfect solution for underfloor heating or solar thermal systems.
• Plumbing Systems: Corrosion resistance and high-pressure tolerance ensure long-term performance in harsh conditions.

An additional advantage is the 15-year warranty on leak-tightness, certified by Technical Approvals from ITB and the Hygienic Certificate from PZH – proof of the highest product quality.
