Compression ball valve PN 10 bar, d 20 × 1/2" (female)

A reliable PN10 compression ball valve is a practical solution for quick shut-off or precise flow control in cold water supply and irrigation systems. This model is designed for installation on high-density polyethylene pipes (PEHD/HDPE/PE) with a 20 mm diameter and for connection to a threaded assembly with a 1/2" female thread. This format is convenient when you need to transition from an HDPE pipe to a threaded fitting, manifold, filter, on-site tap, or an irrigation system component.

The polyethylene body is corrosion-resistant and withstands many external chemical influences, so the valve performs reliably in damp manholes, sumps, outdoors, and in systems where metal components corrode quickly. The PN10 nominal pressure rating (up to 10 bar) covers most household and farming scenarios—from cold water distribution to irrigation, where operating pressure is typically in the 3–6 bar range. The allowable working temperature is up to 40°C, which matches its intended use for cold water.

The ball mechanism is a simple, robust design: rotating the ball provides either full bore flow or complete shut-off. This is why ball valves are valued for tight sealing and long service life under frequent switching. The compression connection ensures even pipe clamping and helps reduce the risk of leaks without specialized tools. The valve is compatible with most fittings used in water supply systems, making it easy to integrate into an existing line.

Installation: fit the valve onto a clean, straight pipe end in the direction of the flow arrow; tighten carefully without over-torquing to avoid damaging the threads; and check for leaks before commissioning. During pressure testing, keep the valve closed; when introducing water, open it slightly so joints do not shift in “live” sections of the line. Designed for long-term use, this valve is an excellent choice if you need a dependable HDPE ball valve with a convenient 1/2" female threaded outlet.
