Product information

Description

FERRO ZZK1 PN16 1/2" check valve is designed for use in water systems to prevent reverse flow and protect pumps, boilers and piping. The valve offers a compact threaded body suitable for installation in residential and light commercial plumbing where unidirectional flow control is required. Compatible with standard 1/2" threaded connections, this PN16-rated check valve is intended for applications with typical domestic water pressures.

Advantages

The valve provides reliable prevention of backflow through a simple, robust mechanism that requires no external power. Its compact construction and threaded connection facilitate straightforward replacement or retrofit in existing pipelines. Rated for PN16 pressure class, the device combines corrosion-resistant materials with a design that minimises flow resistance and maintenance needs.

Suitable for

Domestic cold and hot-water supply systems
Protection of circulation pumps and water heaters
Small commercial plumbing installations
Retrofit or replacement in existing threaded pipelines

Key specifications

Nominal size: 1/2" (threaded)
Pressure rating: PN16
Fluid: water (cold and hot domestic water)
Connection type: standard threaded connection
Flow direction: unidirectional (check valve)
Construction: compact body suitable for confined spaces

How to use

Install the check valve inline with the piping so that the flow arrow on the body matches the intended flow direction. Ensure threaded sealing is applied according to local plumbing practice (for example, thread seal tape or appropriate sealant) and tighten to recommended torque for 1/2" fittings. The valve should be fitted in a position that allows normal flow and prevents trapping of debris; avoid installing in locations where freezing may occur. Inspect connections after installation and perform a pressure test at working pressure to verify there are no leaks and the valve operates correctly.

Usage recommendations

Choose an installation location accessible for inspection. For systems with particulate contamination, install a strainer or filter upstream to reduce the risk of valve blockage. Follow local plumbing codes for materials and installation practice. If used in hot-water systems, verify temperature compatibility with system requirements.
