1-inch water ball valve Hercules nut-screw type with butterfly KMH31

Ball Valve for Water – Reliability and Durability in Every Inch

This Herkules ball valve with a 1-inch diameter is a robust solution for water, heating, and compressed air systems. Manufactured from high-quality brass (CuZn40Pb2 – CW617N) with BSPP threads, it ensures safe and leak-tight connections. Its full-port design minimizes pressure loss, resulting in optimal system performance.

This valve is designed for use with both hot and cold water, as well as glycol solutions, making it a versatile component for any installation. With a pressure rating of up to 40 bar and operational temperatures up to 140°C, it guarantees reliability even under demanding conditions. It holds essential hygiene certifications from the State Hygiene Institute (PZH) and Technical Approvals from the Building Technology Institute (ITB), confirming its suitability for building applications.

Construction and Special Features

The valve features a robust design with meticulous attention to detail. The body and nuts are manufactured via die-casting and precision machined to ensure accuracy and longevity. The ball is chrome-plated and polished to enhance corrosion resistance and prevent seizing. A double PTFE stem seal provides additional protection against leaks. The connection threads feature a high number of turns, facilitating easy installation and ensuring seal integrity. A damping screw integrated into the stem allows adjustment of play, while a nickel-plated finish ensures corrosion resistance and an elegant appearance.

• Durability: Nominal pressure rating of 40 bar and operating temperature up to 140°C ensure long-term service life.
• Leak-tightness: Double PTFE stem seals eliminate the risk of leakage.
• Full bore: No internal restrictions guarantee minimal pressure drop across the medium.
• Longevity: Chrome-plated and polished ball resists seizing; robust construction ensures extended device life.
• Easy installation: Connection threads with high thread count simplify assembly and ensure sealing.
• Adjustability: Stem damping screw allows compensation of play without requiring valve replacement.
• Certifications: Holds ITB Technical Approvals and PZH Hygiene Certificate, confirming compliance with safety and quality standards.
• Potable water compatible: Internal surface meets requirements for direct contact with drinking water.

This valve is an investment in a safe, reliable hydraulic system — ideal for both professional installers and residential users.
