Ball drain valve Perfexim A1809 1/2" (MPN 20-205-0150-000)

The Perfexim A1809 ball drain valve with 1/2" connection is a compact manual shut-off and drain fitting designed for controlled isolation and emptying of fluid lines. Its rotating ball mechanism provides a straightforward open/close action, enabling rapid stoppage of flow and reliable draining of sections of piping or equipment. The valve is intended for installation in plumbing systems where occasional maintenance, seasonal draining or targeted repairs are required.

Advantages

This ball drain valve combines a simple quarter-turn ball operation with a compact body that fits into tight spaces. The 1/2" connection ensures compatibility with common residential and light-commercial plumbing fittings. The design facilitates quick isolation and effective draining without the need to dismantle piping, reducing downtime during servicing. Durable construction and a smooth actuator make manual operation consistent and predictable.

Suitable for

• Isolating and draining sections of water supply or heating lines for maintenance
• Seasonal winterizing of plumbing systems and equipment
• Local repairs where controlled drainage is needed before component replacement
• Drain ports for radiators, boilers, or small process equipment

Key specifications

• Connection size: 1/2" suitable for standard plumbing threads and adapters
• Operation: manual quarter-turn rotating ball for on/off control
• Function: combined shut-off and drain capability for controlled emptying
• Form factor: compact body for installation in confined spaces
• Typical applications: potable water, heating systems and general plumbing use

How to use

Install the valve inline according to the system's flow direction and the manufacturer's recommended tightening procedure. To isolate a section, rotate the valve handle a quarter turn to the closed position; to drain, open the drain outlet and allow fluid to discharge to a suitable collection point. Operate the valve slowly when under pressure and verify downstream isolation before performing maintenance. After draining, return the valve to the desired open or closed position and check for leaks at connections.

Usage recommendations

Use appropriate thread sealant or tape compatible with potable water if required by local codes. For systems under pressure, relieve system pressure upstream before operating the valve to drain. Inspect the valve periodically for signs of wear or leakage and replace if sealing performance degrades.
