## Summary description

ARCO check valve model 190205 is a flap-type non-return valve with 1" internal (female) thread and a rubber seat closure. Designed to prevent backflow in piping systems, it suits water and liquid circuits where a reliable one-way seal is required. Typical uses include domestic and industrial plumbing, pump discharge lines and circulation systems.

## Long description

ARCO check valve 190205 is a flap-type non-return valve with a 1" internal (female) threaded connection and a rubber seat closure. It is designed to allow flow in one direction and to prevent backflow in water and liquid circuits. The valve's simple flap mechanism and elastomer seat provide a compact solution for controlling reverse flow in domestic plumbing, pump discharge lines and circulation systems.
Advantages
The flap design ensures rapid response to flow changes and low head loss during normal operation. The rubber seat closure provides a tight seal against reverse flow and compensates for minor misalignments. The internal thread simplifies installation into threaded piping or fittings without additional adapters, and the valve's compact dimensions make it suitable for confined spaces.
Suitable for
 Domestic water supply and drainage systems
 Pump discharge lines to prevent backflow
 Circulation and recirculation loops in heating or cooling circuits
 General liquid piping where a one-way seal is required
Key specifications
 Type: flap (swing) non-return valve
 Connection: 1" internal (female) thread
 Sealing: rubber (elastomer) seat closure
 Media: water and compatible liquids
 Installation orientation: inline, flow direction dependent on flap hinge
How to use
Install the valve into a compatible 1" female-threaded port or pipe using appropriate thread sealant or tape on the male thread to ensure a leak-tight joint. Observe the flow direction indicated by the flap orientation so the valve opens toward the flow and closes against backflow. Ensure the valve is accessible for inspection and free from debris that could prevent the flap from sealing properly. Avoid exposing the rubber seat to aggressive chemicals or temperatures outside the valve's material limits.
Usage recommendations
Check the valve periodically for wear, deposits or seal deterioration and replace if the rubber seat shows signs of hardening or damage. When used with pumps, install the valve close to the discharge to minimise water hammer and to protect upstream equipment; confirm compatibility of the valve's rubber seat with the specific liquid in the system.
