Ball valve with drain Perfexim 1" model 01-303-0250-000

Perfexim 1" ball valve with integrated drain valve (model 01-303-0250-000) is a compact plumbing fitting designed to control fluid flow while providing a dedicated drain outlet for controlled bleeding or system emptying. The valve offers a standard 1" connection suitable for many pipe assemblies and delivers quarter-turn operation for fast opening and closing. Intended for use in heating and water systems, this ball valve combines isolation capability with convenient maintenance access through its built-in drain.

Advantages

The valve integrates a shut-off ball mechanism and a separate drain outlet in a single compact body, reducing the need for additional fittings. Quarter-turn operation ensures quick and clear on/off control with minimal effort. The dedicated drain port allows controlled depressurisation or partial system emptying for maintenance tasks. Its standard 1" connection simplifies installation into existing pipework and minimizes adaptation requirements.

Suitable for

• Domestic and commercial heating systems requiring isolation and periodic draining
• Hot and cold water supply lines where controlled bleed-off is needed
• Plumbing assemblies where compact isolation with drainage simplifies maintenance
• Sections of piping that require occasional flushing, venting, or pressure release

Key specifications

• Connection size: 1 inch threaded connection compatible with standard 1" pipe fittings
• Operation: quarter-turn ball valve for rapid open/close action
• Integrated drain outlet for controlled draining or bleed-off
• Compact body designed for space-constrained installations
• Application: suitable for water and heating systems

How to use

Install the valve in-line with the system piping using the standard 1" connection, ensuring proper sealing and alignment according to local plumbing practices. Use the lever to turn the ball valve a quarter turn to open or close the main flow. Operate the integrated drain outlet to bleed or partially drain the downstream section; close the drain before restoring system pressure. Follow applicable safety procedures when working on live systems, including isolating mains and relieving pressure where required.

Usage recommendations

For reliable performance, verify compatibility with system medium and operating temperature range prior to installation. During installation, use appropriate sealing materials and avoid overtightening threaded connections. Periodically operate the drain to prevent sediment build-up and check for leaks after first use and after maintenance operations.
