Check valve kfa² 6/4" cast iron model 192-010-40

Cast iron check valve kfa² 6/4" model 192-010-40 is a single-direction valve designed for reliable prevention of backflow in piping systems. Built from cast iron, this check valve is intended for use in water and heating installations where a robust body and straightforward operation are required. The valve supports uninterrupted flow in the intended direction while closing to stop reverse flow, helping to protect pumps, boilers, and other system components.

Advantages

The cast iron construction provides mechanical strength and resistance to wear in typical plumbing and heating environments. The simple internal mechanism ensures fast response to flow changes and minimal maintenance requirements. Designed for compatibility with standard pipe fittings, the valve offers straightforward installation and stable performance under normal operating conditions.

Suitable for

• Domestic and commercial water supply systems
• Heating circuits and boiler return lines
• Circulation lines in hydronic systems
• Pump protection to prevent reverse flow

Key specifications

• Material: cast iron body
• Nominal size: 6/4"
• Function: non-return / check valve (one-way flow)
• Typical media: water for heating and plumbing systems
• Connection: compatible with standard threaded or flanged pipe fittings depending on installation

How to use

Install the check valve in the pipeline with the flow direction arrow aligned with the intended flow. Ensure pipe ends and threads are clean and properly sealed according to the pipe fitting method chosen. After installation, slowly pressurize the system and inspect for leaks. Periodic visual inspection during routine system maintenance is recommended to confirm proper seating of the internal mechanism and absence of external leakage.

Usage recommendations

Use this valve in systems carrying clean water or typical heating fluids; avoid aggressive chemical media that may corrode cast iron. Confirm compatibility of connection type and size with existing piping. For installations in critical systems or where higher corrosion resistance is required, consider material and coating options appropriate for the specific application.
