Check valve ARCO VITAQ 6/4" (191207) non-return valve for fluid systems

ARCO VITAQ 6/4" check valve is a non-return valve engineered to maintain one-way flow in fluid systems and piping. Sized at 6/4" (1.5 inches), this inline valve automatically closes to prevent backflow, protecting pumps and other system components. It is suitable for water and heating circuits as well as general plumbing applications where reliable directional flow control is required.

Advantages

The ARCO VITAQ check valve offers automatic, maintenance-friendly operation with straightforward inline installation. Its compact design reduces system complexity while providing consistent closing action to avoid reverse flow and water hammer. Constructed for common plumbing and heating environments, the valve supports stable operation of pumps and prevents contamination or pressure disturbances caused by backflow.

Suitable for

• Domestic and commercial water supply lines
• Heating system circuits (radiators, boilers, circulation loops)
• Pump protection in booster and circulation systems
• General plumbing installations requiring one-way flow control

Key specifications

• Nominal size: 6/4" (1.5 inches)
• Function: Check (non-return) valve for one-way flow
• Installation: Inline piping mount
• Typical media: Water and heating fluids suitable for standard plumbing systems
• Operation: Automatic closing to prevent backflow

How to use

Install the valve in the pipeline in the correct flow direction, ensuring the arrow on the valve body matches the intended flow. Secure the valve using appropriate thread or coupling methods for the existing piping material and size. After installation, pressurize the system and check for leaks and proper unidirectional operation by verifying that flow passes in the intended direction and that no reverse flow occurs when pumps stop.

Usage recommendations

When selecting and installing the ARCO VITAQ 6/4" check valve, confirm compatibility with the system's pressure and temperature ranges and use suitable sealing materials for the pipe connections. Periodic visual inspection and leak checks during routine system maintenance help ensure long-term reliable operation. In applications with high particulate content, consider upstream filtration to avoid wear or sticking of the valve mechanism.
