## Long description

Straight ball valve ARCO SL1112 1/2" female x 1/2" female with a stainless steel lever is a compact quarter-turn shutoff valve designed for fluid isolation in solar thermal and plumbing systems. The valve body and ball are engineered to provide reliable sealing performance and resistance to corrosion, making it suitable for potable water and heat-transfer circuits where compactness and durability are required.
Advantages
The stainless steel lever ensures durable manual operation and improved corrosion resistance compared with painted or plated handles. Quarter-turn operation allows rapid opening and closing, reducing service time during maintenance or emergency shutoff. The straight, union-style threaded connections provide straightforward installation in line with standard 1/2" female fittings, supporting tight sealing and minimal pressure drop in typical domestic and commercial circuits.
Suitable for
 Solar thermal system shutoff and zone isolation
 Domestic potable water supply lines
 Heat-transfer circuits and glycol-based closed loops
 Plumbing maintenance and replacement of existing 1/2" valves
Key specifications
 Connection type: straight 1/2" female x 1/2" female threaded
 Actuation: manual stainless steel lever, quarter-turn
 Material: corrosion-resistant components suitable for water and heat-transfer fluids
 Flow characteristic: full-bore quarter-turn ball for low pressure drop
 Typical applications: potable water and solar thermal/heating circuits
How to use
Install the valve in-line between matching 1/2" female threaded fittings, using appropriate sealing material on the threads if required by the system. Turn the stainless steel lever 90° to open or close the flow; the lever position indicates valve status (parallel to flow = open, perpendicular = closed). Operate the valve only by hand and avoid applying excessive torque to the lever. Prior to installation, flush the pipeline to remove debris that could affect sealing surfaces.
Usage recommendations
For reliable long-term performance in solar thermal systems, ensure the valve is installed in an accessible location for periodic inspection and operate it occasionally to prevent seizing. Confirm compatibility with system fluids, particularly when using antifreeze solutions, and follow local plumbing codes for thread sealing and pressure ratings.
