## Summary description

Thermostatic straight valve Comap D3805E is a 1/2" heating system valve with factory presetting for flow regulation in radiator and convector circuits. Designed for temperature control and hydraulic balancing, it enables accurate presetting of flow rate and stable room temperature. Suitable for residential and light commercial HVAC installations.

## Long description

The thermostatic straight valve Comap D3805E 1/2" with presetting is a compact radiator valve designed for regulating flow in heating circuits. Manufactured by Comap, this valve integrates factory presetting to set a defined maximum flow and is intended for temperature control and hydraulic balancing in residential and light commercial HVAC systems. The straight configuration and 1/2" connection size make it compatible with common radiator and convector installations, allowing accurate flow limitation and facilitating stable room temperature regulation.
Advantages
The Comap D3805E valve provides precise flow presetting at the factory, which reduces the need for on-site adjustments and speeds up commissioning. Its straight design allows direct inline installation on radiator and convector circuits, while the 1/2" connections match standard piping. Built for hydraulic balancing and thermostatic control, the valve supports even heat distribution and helps prevent oversupply to individual emitters. Materials and construction are selected for compatibility with typical heating fluids and system pressures used in residential and light commercial installations.
Suitable for
Radiator and convector circuits in residential heating systems
Light commercial HVAC installations requiring hydraulic balancing
Applications where factory presetting of maximum flow is desired
Retrofit projects replacing manual valves with thermostatic control
Key specifications
Connection type: straight inline valve with 1/2" nominal connections
Function: thermostatic control with factory presetting for flow limitation
Primary purpose: flow regulation and hydraulic balancing in heating circuits
Application environment: residential and light commercial HVAC systems
Compatibility: suitable for use with common heating fluids and standard radiator/convector fittings
How to use
Install the Comap D3805E valve in a straight inline position on the radiator or convector supply or return line, ensuring correct orientation according to the flow direction indicated on the body. Connect using compatible 1/2" fittings and tighten to manufacturer-recommended torque values. The valve arrives with factory presetting; verify the preset position and adjust only if system-specific balancing requires a different maximum flow. Pair the valve with an appropriate thermostatic head or actuator where automatic temperature regulation is needed.
Usage recommendations
Verify system cleanliness and pressure before installation and flush the circuit if necessary to avoid debris affecting valve operation. When adjusting presetting on-site, follow hydraulic balancing procedures and use measurement instruments to confirm flow rates. For compatibility with specific thermostatic heads, consult the head supplier’s instructions and ensure correct mounting and calibration.
