Start valve with compression for plastic pipe, Dn17 (KSP 17)

A Reliable Component for Irrigation Systems

In the field of drip irrigation components, Santechplast has long established itself as a benchmark for durability and cost-effectiveness. The starter valve with compression nut Dn17 (KSP 17) is a workhorse, favored by both hobbyist gardeners and farmers managing large-scale irrigation systems. Its robust design is intentionally simple, minimizing the risk of mechanical failure during the intensive farming season.

Engineering and Installation

The hallmark of the KSP 17 model is the compression nut. Unlike traditional barbed fittings that rely solely on physical pressure for connection, this valve is securely locked onto the main pipe. The compression nut ensures a watertight seal even when system pressure fluctuates, which is crucial for setups powered by pumping stations.

• Diameter: 17 mm, making it a universal choice for standard drip tubing and irrigation lines.
• Material: Primary polypropylene fortified with UV stabilizers to prevent degradation and cracking when exposed to direct sunlight.
• Valve Mechanism: A smooth-operating rotating valve that allows for precise water flow control for individual crop rows.

Santechplast engineers have optimized the geometry of this component to withstand standard drip irrigation working pressures, preventing leaks at the connection point. The company’s reputation is built on consistent quality, ensuring that every valve fits perfectly into an opening made with a standard hole punch.

Typical Application

The KSP 17 is most commonly used to connect drip tape or tubing to rigid PVC mainlines. It is indispensable for systems that require section-based irrigation management. Installation is straightforward: drill a 16 mm hole, insert the fitting, and tighten the nut. Using the KSP 17 eliminates the need to fully dismantle the irrigation system in winter—simply draining the water and partially opening the valves is enough to prevent frost damage.
