Sliding Drain with Ball AZO PV-WPZK

AZO PV-WPZK is a sliding drain with a ball mechanism designed for controlled fluid discharge in compact liquid handling systems. The device provides adjustable flow by means of a movable ball element that slides to open or restrict the passage, allowing precise regulation of drainage in sanitary fittings, process equipment and industrial drainage points. It is intended for integration or replacement where a mechanically simple, low-profile drain control is required.

Advantages

The sliding ball mechanism offers smooth, repeatable adjustment of flow without electronic control, reducing complexity and maintenance needs. The compact construction enables installation in confined spaces and can be mounted in a variety of orientations. Mechanical simplicity improves reliability and minimizes the number of wear-prone parts, while the movable ball provides a positive seal when closed and predictable flow characteristics when open.

Suitable for

• Sanitary fittings and washbasin drainage points
• Small-scale process vessels and tanks requiring adjustable drainage
• Industrial workplaces and production lines with compact liquid discharge needs
• Replacement of existing mechanical drains with a low-profile control element

Key specifications

• Operating principle: sliding ball element for adjustable flow control
• Installation: inline or panel-mounted in compact drainage assemblies
• Control type: manual mechanical adjustment (no electronics)
• Sealing: positive ball-to-seat contact for closed position
• Construction: compact design suitable for confined spaces

How to use

Install the sliding drain in the designated drainage line or mounting point following the system's mechanical interface requirements. Adjust the ball position manually to achieve the desired flow rate; move the ball toward the closed position to reduce or stop flow and toward the open position to increase discharge. Check seating for a secure seal after adjustment. Routine inspection of the ball and seating surface is recommended to ensure consistent performance and to identify wear or debris that could affect sealing and flow control.

Usage recommendations

Use the component within the fluid compatibility and temperature ranges of the installation; avoid abrasive particulates in the flow that can accelerate wear. Periodically clean the ball and seat and verify manual movement to maintain predictable control. For critical applications, perform functional checks after installation and consider installing a filter upstream to protect the moving parts.
