## Summary description

SOL-ARM KOREK PE 25 is a SOL-ARM drainback/drain valve, model PE-67-025, designed for solar thermal and fluid drainage applications. The product name indicates a PE 25 size variant suitable for system drainage, protection from frost and unattended fluid discharge. Use cases include solar collector systems, maintenance draining and controlled fluid removal in heat-exchange installations.

## Long description

The SOL-ARM KOREK PE 25 is a drainback valve designed for solar thermal systems and fluid drainage applications. Intended as a component for controlled removal and protection of heat-transfer fluids, the valve supports system drainage to prevent freeze damage and to enable maintenance operations. The PE 25 size variant fits installations requiring a polyethylene-based valve suited for return-flow and gravity-drain configurations in solar collector and heat-exchange setups.
Advantages
The drainback valve provides reliable gravity-driven drainage to reduce the risk of fluid freezing in collectors and piping when the system is not operating. Its design enables unattended fluid discharge and helps protect pumps and collectors during prolonged shutdowns. The valve is compatible with standard solar installation practices and simplifies maintenance by allowing controlled emptying of circuit sections without complex tools.
Suitable for
Solar thermal collector systems requiring drainback protection
Maintenance draining of heat-exchange circuits
Gravity-drain installations where passive fluid removal is required
Systems needing protection from frost during idle periods
Key specifications
Valve type: drainback/drain valve suitable for gravity-driven fluid removal
Material: polyethylene-compatible construction for use with typical solar heat-transfer fluids
Size: PE 25 nominal connection size for medium-diameter solar piping
Operation: passive, no electrical power required; operates by gravity or pressure reversal
Intended application: solar thermal and heat-exchange installations for protective drainage
How to use
Install the drainback valve in the return or low point of the solar circuit following piping orientation recommended for gravity drainage. Ensure connections match the PE 25 nominal size and are secured according to system pressure ratings. During commissioning, verify that the valve opens and allows fluid to drain when pumps are off or when the system is depressurized. Use the valve as part of a planned maintenance procedure to empty sections of piping and protect collectors from freezing.
Usage recommendations
Regularly inspect connections and sealing surfaces for wear or leakage, and confirm compatibility between the valve material and the system heat-transfer fluid. Test the drainback action during routine servicing and before winterizing the installation to ensure reliable operation.
