Start valve, male thread 1/2" for plastic pipe Dn17*1/2" (KSN 17x1/2")

Reliable Drip Irrigation Integration

The Santechplast starter valve with 1/2" male thread is a fundamental component for building irrigation mainlines. It is designed for those who prefer classic, robust connections with rigid mounting. Unlike standard barbed connectors for drip tapes, the KSN 17x1/2" model provides a more predictable and secure connection when transitioning from a rigid pipe to a drip line.

Design and Installation Highlights

The key differentiator of this valve is its mounting method. The 1/2" male thread requires pre-installation into the mainline (usually PVC or HDPE) via a tee or elbow with a female thread. This design is ideal for systems requiring high mechanical durability and long-term stability.

• Material: High-quality virgin polypropylene, resistant to UV rays and fertilizers.
• Sealing: The lever mechanism ensures smooth operation and precise locking in both 'open' and 'closed' positions.
• Compatibility: Specifically engineered for standard 17mm drip irrigation tubing.

Who is this for?

This valve is an optimal choice for farmers who utilize thread-based fittings for their stationary or seasonal irrigation setups. It is more forgiving during installation compared to pressure-fit connectors and is easily removable at the end of the season. However, keep in mind that installation requires additional hardware (threaded tees), which slightly increases the assembly cost compared to simple hole-punch starter connectors.
