Weiß PVC Kugelhahn Kugel Ventil Innengewinde Muffen Fittings Pond 20-160mm

Match the inner diameter (ID) of the valve socket to the outer diameter (OD) of your PVC pipe. For example, a 20 mm socket variant fits standard 20 mm OD metric PVC pipe. If you are connecting to threaded pipe, select the female-thread variant that matches your pipe's BSP or NPT thread size (e.g., 25 mm = 3/4" BSP).

Socket (slip) variants are designed for solvent-weld (glue) connections to plain-end PVC pipe — the pipe slides into the socket and is bonded with PVC cement. Female-thread (Innengewinde) variants have internal threads that accept male-threaded pipe or fittings, allowing tool-tightened, removable connections without adhesive.

Yes. Rigid PVC is non-toxic, does not leach metals, and is widely used in pond, aquaculture, and water garden plumbing. It is safe for use in systems housing fish and aquatic plants when properly installed and cured (for solvent-weld joints, allow full cure time before introducing water).

PVC ball valves are lighter than brass or stainless steel and offer excellent resistance to corrosion and most common chemicals. They are well-suited for low-to-medium pressure water systems (typically up to 10 bar for smaller sizes, decreasing for larger diameters). For high-pressure or high-temperature applications, consult the pressure rating for your specific size variant.

Yes. PVC has excellent resistance to chlorine, chloramines, and most pool and spa treatment chemicals at standard concentrations. This makes these valves a practical choice for swimming pool bypass lines, chemical dosing systems, and water treatment installations.

PVC can become brittle with prolonged UV exposure over many years. For outdoor installations in direct sunlight, consider wrapping the valve in UV-protective tape or insulation, or housing it in a valve box. For shaded outdoor or underground applications, no additional protection is typically needed.

For socket (slip) variants: PVC pipe cutter, PVC primer, and solvent cement — no power tools required. For female-thread variants: PTFE thread tape and an adjustable wrench or pipe wrench to tighten the male-threaded pipe into the valve. The valve handle itself requires no tools to operate after installation.
