Ball drain valve Valvex ONYX 2" model 1457650

Ball drain valve Valvex ONYX 2" model 1457650 is a manual drain valve designed to evacuate liquids from pipelines, tanks and equipment. The valve uses a ball closure mechanism that enables reliable shut-off and controlled discharge through a 2" connection. It is suitable for use in plumbing, heating and industrial installations where periodic draining, maintenance or system commissioning is required.

Advantages

The ball closure provides smooth operation and a clear open/closed position for precise control of discharge. A robust construction ensures long service life under typical plumbing and heating conditions. The 2" connection size allows for rapid flow during draining operations, reducing the time required for emptying systems. Manual actuation requires no external power and permits simple maintenance and replacement if needed.

Suitable for

• Draining water, heat transfer fluids and other non-aggressive liquids from pipelines and tanks
• Maintenance and servicing of heating systems, boilers and hot-water circuits
• Evacuation of system sections during commissioning or repair work
• Industrial applications where a manual, reliable drain is required

Key specifications

• Connection size: 2 inches
• Valve type: ball drain valve with manual actuation
• Function: on/off drain and controlled discharge
• Typical applications: plumbing, heating, industrial draining

How to use

Install the valve in a suitable location of the pipeline or equipment following piping direction and accessibility for manual operation. Ensure connections are tightened to appropriate torque and that seals or gaskets compatible with the conveyed liquid are used. To drain, move the ball handle to the open position to permit flow; monitor discharge and close the valve by returning the handle to the closed position when draining is complete. During maintenance, isolate the section upstream and downstream as required and follow applicable safety and depressurization procedures.

Usage recommendations

Use the valve only with compatible fluids and within the pressure and temperature limits recommended by the installation standards. Regularly inspect for leaks and proper sealing, and perform preventive maintenance such as lubricating moving parts and replacing worn seals to maintain reliable operation.
