Product information

Description

FERRO ZZK3 PN16 1" check valve is a compact inline valve designed to maintain one-way flow and prevent reverse flow in water systems. Engineered for compatibility with PN16 pressure ratings, this check valve is suitable for installation in domestic and commercial plumbing, heating circuits and pump lines. The valve's construction focuses on reliable operation and protection of downstream equipment from backflow and transient pressure effects such as water hammer.

Advantages

The valve offers straightforward one-way flow control with PN16 pressure compatibility, allowing integration into a wide range of water installations. Its compact inline body minimizes space requirements and simplifies installation in tight pipe runs. The design reduces the risk of reverse flow that can damage pumps, meters and heating components, and contributes to smoother system operation by mitigating sudden pressure spikes. Materials and construction are selected for corrosion resistance and long service life in typical water system conditions.

Suitable for

Domestic cold and hot water supply lines
Heating system circulation loops and radiators
Pump discharge and suction protection in booster sets
Commercial plumbing installations with PN16 pressure requirements

Key specifications

Nominal size: 1" (one inch)
Pressure rating: PN16 (suitable for systems up to PN16)
Function: check valve (one-way flow, anti-backflow)
Connection type: inline threaded connection for standard piping
Medium: potable water, heating water and general water service

How to use

Install the FERRO ZZK3 check valve in the pipe run following the flow direction indicated on the valve body. Ensure the valve is positioned so that the flow is in the correct orientation to prevent backflow. Use appropriate sealing and thread preparation for the pipe thread type in your installation. Avoid installing the valve in positions where debris accumulation is likely; where necessary, provide strainers or filters upstream to protect the valve mechanism. Confirm system pressure does not exceed PN16 limits before operation.

Usage recommendations

For reliable performance, install the valve in a straight section of pipe with recommended upstream and downstream straight lengths as specified by the system designer. Periodically inspect for signs of leakage, wear or debris; flush or clean the upstream strainer if flow becomes reduced. During system commissioning, check for correct valve operation by verifying one-way flow and absence of reverse flow when pumps are stopped.
