Viega ProPress Hose Cap Ball Valves: Built for Performance and Peace of Mind
We listened to our customers—and delivered. Designed for today’s demanding potable and hydronic systems, Viega’s Hose Cap Press Ball Valve Models 2971.6ZL (Zero Lead for potable water) and 2973.3 (for hydronics) are certified to IAPMO/ANSI Z1157 and rated to 300 PSI. These are some of the only valves to meet this performance standard.
Applications for Hose Cap Valves
Hose valves are a critical factor in maintaining the integrity and safety of fluid systems, ensuring isolation shut off and drain down applications. Our hose cap ball valves are ideal for closed-loop, chilled water and hydronic systems—which we see in applications like data centers, schools and mechanical rooms. They are purpose-built for systems with drain-down conditions—like glycol drainage—where safety and reliability are critical.

These products have undergone comprehensive testing to ensure mechanical integrity, durability and hose cap retention. The compact, durable design ensures the hose cap remains sealed under pressure, mitigating the risk of accidental discharge if the valve is inadvertently pushed into the open position. This bolsters a peace of mind in high-pressure system environments such as data centers, schools and mechanical rooms.
Hose valves are a critical factor in maintaining the integrity and safety of fluid systems. They directly aid in isolation shut off leak prevention and ensuring that the right amount of fluid reaches its destination.
