Check valve with strainer ARCO 3/4" female thread (model 190804)

ARCO 3/4" female check valve with integrated strainer (model 190804) is a compact inline fitting designed to prevent backflow and to capture particulate debris in water systems. The unit combines a one-way valve function with a built-in screen, providing basic protection for pumps, fixtures and piping against sediment and foreign matter. Intended for residential and light commercial plumbing, this check valve simplifies installation where space is limited and particulate protection is needed.

Advantages

The combined check valve and strainer design reduces the number of fittings required and saves installation time while maintaining backflow prevention and debris filtration. Its female threaded 3/4" connection allows compatibility with common pipe fittings and fixtures. The inline, compact construction is suitable for tight spaces and straightforward maintenance, and the strainer element helps protect downstream equipment such as pumps and valves from clogging.

Suitable for

• Domestic water supply lines
• Pump suction and discharge connections
• Pre-filtration before fixtures and valves
• Small commercial plumbing installations

Key specifications

• Connection type: 3/4" female thread
• Function: check (non-return) valve with integrated strainer
• Installation: inline, compact form factor
• Medium: potable water and general water systems
• Application: prevents backflow and traps particulate debris

How to use

Install the unit in the pipeline with correct flow direction indicated by the valve body marking. Use appropriate thread sealant or tape on the mating male threads and tighten to the torque recommended for the pipe material to avoid damage. Position the valve so the strainer access (if removable) is reachable for periodic inspection and cleaning. After installation, run the system and check for leaks and correct one-way flow operation before returning to normal service.

Usage recommendations

Regularly inspect and clean the strainer element to maintain flow and protect downstream equipment; frequency depends on water quality and system usage. Do not subject the valve to temperatures or pressures beyond those specified for your piping system. For installations requiring certified backflow protection or fine filtration, consider additional devices appropriate to local regulations and system requirements.
