## Summary description

CALEFFI ball valve model 327500 is a compact valve assembly for heating installations combining a shut-off ball valve with an integrated check (non-return) valve. Designed for use in central heating and hydronic systems, it enables flow shut-off and prevents backflow without separate components. Suitable for manifold connections, pump circuits and maintenance isolation tasks.

## Long description

CALEFFI ball valve with integrated check valve model 327500 is a compact assembly engineered for heating and hydronic systems. It combines a shut-off ball valve with an internal non-return mechanism to provide flow isolation and backflow prevention in a single component. The valve is intended for installation on manifolds, pump circuits and branch lines where space is limited and reliable isolation is required for maintenance or system configuration.
Advantages
The combined design reduces the need for separate components, saving installation time and minimizing leak points. The unit's compact form factor simplifies placement in confined spaces near boilers, pumps or manifold assemblies. Integrated check functionality ensures unidirectional flow and protects system components from reverse flow without the need for an additional non-return valve. Materials and construction are selected to withstand typical temperatures and pressures in central heating circuits while maintaining easy operation and serviceability.
Suitable for
Central heating distribution manifolds
Hydronic pump circuits and recirculation loops
Branch isolation for maintenance or component replacement
Compact installations where combined shut-off and check functions reduce space and parts count
Key specifications
Function: Shut-off ball valve with integrated non-return (check) valve
Application: Central heating and hydronic systems
Connection types: Suitable for manifold and pump circuit connections (consult installer for exact thread/connection compatibility)
Design: Compact combined assembly to reduce installation space and components
Operation: Manual lever or handle operation for on/off isolation
Performance: Designed for standard heating system temperatures and pressures; manufactured for durability in circulating hot water systems
How to use
Install the valve in the desired location on the heating manifold or pump line following applicable plumbing codes and system layout. Ensure correct flow orientation by aligning the integrated check valve direction with system flow. Use the lever or handle to close the ball valve for isolation during maintenance or component replacement; opening the valve restores flow while the internal check prevents reverse flow. Commission the circuit and check for leaks at connections before returning the system to normal operation.
Usage recommendations
Specify the valve location and connection type during system design to confirm compatibility with manifolds and pump fittings. During installation, verify flow direction and torque fittings to manufacturer or installer guidelines. Periodic inspection during routine maintenance is recommended to ensure reliable sealing and check valve operation; if unusual noise or reverse flow is detected, isolate the circuit and inspect the valve assembly.
