## Long description

Compact INVENA MINI ball valve ZK-57-C15 with a compression gland and a PEX male connector GZ½" × 16mm × 2mm is designed to control flow in plumbing and heating installations. The valve connects to PEX pipes with a 16 mm outer diameter and 2 mm wall thickness via a G½" male threaded connector and a compression fitting, providing a compact shut-off solution for residential and light commercial systems.
Advantages
The INVENA MINI ball valve offers a compact form factor that saves space in tight installation locations. Its compression gland enables a reliable mechanical seal to PEX piping without the need for soldering, and the G½" male threaded connector simplifies connection to existing fittings. The ball mechanism allows quick on/off operation with minimal pressure drop and low maintenance requirements.
Suitable for
 Shut-off points in domestic water supply lines

 Light commercial plumbing installations with PEX piping
Key specifications
 Connection type: compression gland plus male threaded connector
 Thread size: G½" (male)
 PEX compatibility: for pipes 16 mm outer diameter, 2 mm wall thickness
 Operation: quarter-turn ball valve
 Application: plumbing and heating systems
 Material: corrosion-resistant components suitable for potable water systems
How to use
Install the valve by sliding the compression sleeve and nut onto the PEX pipe, inserting the pipe into the fitting until it seats, and tightening the compression nut to obtain a secure mechanical seal. Thread the G½" male connector into the mating female fitting and tighten to the recommended torque. Operate the valve using a quarter-turn of the handle to open or close the flow. Follow local plumbing codes and use appropriate tools and sealing materials where required for threaded joints.
Usage recommendations
For durable performance, verify pipe dimensions before installation, avoid overtightening the compression nut, and perform a pressure test after installation. Use the valve within the temperature and pressure limits specified for PEX systems and replace if signs of leakage or mechanical damage appear.
