Product information

Description

FERRO ZZK2 PN16 3/4" check valve is designed for plumbing and heating installations where prevention of reverse flow is required. The valve provides reliable unidirectional flow control with a PN16 pressure rating and standard 3/4" connection size. It is intended for use in water distribution, heating circuits and other general fluid systems compatible with PN16 operating conditions.

Advantages

The valve offers a compact design with a corrosion-resistant body suitable for typical residential and commercial systems. Its construction minimises pressure loss while ensuring quick closure to protect pumps and pipework from backflow. The PN16 rating makes it compatible with common cold and hot water installations as well as many heating systems.

Suitable for

  • Domestic and commercial water distribution systems
  • Heating circuits and boiler systems
  • Protection of pumps and circulators from reverse flow
  • General fluid distribution where PN16 compatibility is required

Key specifications

  • Connection size: 3/4"
  • Pressure rating: PN16
  • Flow direction: unidirectional (check valve)
  • Typical applications: potable water, heating circuits, circulation lines
  • Material characteristics: corrosion-resistant valve body suitable for plumbing use

How to use

Install the check valve in-line with the flow direction clearly indicated on the body; ensure the inlet and outlet are connected according to system flow. Tighten connections to appropriate torque for the chosen pipe fittings and pressure class. After installation, pressurise the system and inspect for leaks. Regular checks during maintenance cycles will verify correct operation and ensure the valve closes properly under reverse flow conditions.

Usage recommendations

Install the check valve in accessible locations to allow inspection and maintenance. Avoid installation points subject to high debris without upstream filtration; if used with heating systems, follow system flushing and water quality guidelines to prolong valve life.
