## Long description

Compact INVENA MINI ball valve ZK-57-N15 features a gland packing and a PEX-compatible fitting with a G½" male thread to 16×2 mm connection. Designed for domestic plumbing and heating systems, this small ball valve provides reliable shut-off control for water flow on PEX pipes and is intended for use where space is limited. The valve body and connection geometry are optimized for simple integration with PEX pipelines and standard threaded fittings.
Advantages
The valve combines a compact form factor with a gland packing that enables maintenance and seal replacement without removing the entire fitting. Its G½" male thread mates with common fixtures while the 16×2 mm PEX connection ensures a secure push-fit joint. The design minimizes the footprint in confined installation locations and allows straightforward manual operation for shut-off and flow control.
Suitable for
Domestic cold and hot water supply lines using 16×2 mm PEX tubing
Under-sink shut-off applications in kitchens and bathrooms
Compact heating system branches and radiator supply lines
Tight spaces where a low-profile serviceable valve is required
Key specifications
Connection type: G½" male thread to 16×2 mm PEX fitting
Valve type: quarter-turn ball valve with gland packing
Pipe compatibility: 16×2 mm PEX tubing
Operation: manual lever for on/off control
Installation position: suitable for inline installations in confined spaces
How to use
Prepare the PEX pipe by cutting it square and deburring the end. Insert the pipe fully into the 16×2 mm PEX fitting until the push-fit engagement is felt and the connection is seated against the stop. Thread the G½" male end into the corresponding female fitting and tighten to the recommended torque for a leak-free joint. Operate the manual lever a quarter turn to open or close the valve. To service the gland packing, isolate the system and relieve pressure before adjusting or replacing the packing to maintain sealing performance.
Usage recommendations
Use compatible 16×2 mm PEX tubing and appropriate installation tools. Before final assembly, verify pipe insertion depth and ensure threaded joints are sealed according to local plumbing standards. For safety, isolate and depressurize the section before performing maintenance on the gland packing or any connections.
