Ball drain valve INVENA ZW-62-015 GZ 1/2" with hose tail and cap

INVENA ZW-62-015 GZ 1/2" ball drain valve with hose tail and cap is a compact shut-off valve designed for controlled draining and flushing of plumbing systems, radiators and domestic appliances. The valve features a quarter-turn ball mechanism for quick opening and closing, a GZ 1/2" threaded inlet for standard connections and an integrated hose tail that allows direct attachment of a drain hose. A protective cap covers the hose tail when not in use to prevent debris ingress and to keep the connection clean.

Advantages

The ball drain valve provides reliable, leak-resistant operation with a simple quarter-turn action, enabling fast isolation and drainage. The built-in hose tail simplifies connection to standard garden or drain hoses, eliminating the need for adapters in many situations. The protective cap keeps the hose tail free from dirt and reduces the risk of contamination. Its compact design fits easily into tight installation spaces and is suitable for both residential and light commercial plumbing applications.

How to use

Shut off the supply to the section of the system to be drained. Thread the valve into a compatible GZ 1/2" connection or install it in place of an existing drain connection. Attach a suitable hose to the hose tail and secure it with a clamp if needed. Turn the valve handle a quarter turn to open and allow controlled drainage. After draining, close the valve by returning the handle to the closed position and remove the hose if required, then replace the protective cap to keep the tail clean.

Usage recommendations

Use the valve with compatible threaded fittings and hoses rated for the expected water temperature and pressure. When installing in heating systems, ensure the system is cooled before draining and follow local codes for safe disposal of system fluids. Periodically inspect the cap and hose tail for debris and wear, and replace the valve if leakage or damage is detected.
