Heavy duty brass construction for long lasting performance. Made from solid brass, this valve offers rust resistance and maintains strength in varied weather, making it suitable for outdoor water and gas line applications that require reliability. Automatic temperature activation. The integrated Temperature Control Valve activates mechanically at 1C to forestall freezing, then closes above 6C to reduce water waste. It operates without electricity for dependable freeze management. Effective freeze protection. The valve automatically drains cold water when the threshold is reached, protecting residential or commercial plumbing and outdoor installations from pipe cracking. Wide compatibility and sizing. The Manual Ball Valve fits G1/2 threading for a secure link and is compatible with outdoor solar water systems, gas boilers, and municipal pipelines, providing adaptability across multiple plumbing setups.
