## Long description

Thermostatic Radiator Valve Set INVENA IECD-74-P15 with Mini Adjustable Head and Pre-setting is a compact valve assembly designed to regulate hot-water flow to radiators and maintain stable room temperature. The set comprises a thermostatic valve body and a small-profile adjustable head with pre-setting capability, allowing precise flow limitation and temperature control in confined installation spaces. It is intended for domestic and light commercial heating systems where efficient balancing and space-saving components are required.
Advantages
The mini adjustable head offers a reduced footprint that fits tight radiator connections while preserving full thermostatic functionality. Pre-setting on the valve body enables balancing of the heating circuit by restricting maximum flow, which simplifies commissioning and helps maintain even heat distribution. The set provides automatic temperature control, reducing manual intervention and helping to stabilize indoor climate. Materials and design focus on reliable operation and ease of installation in standard radiator applications.
Suitable for
Apartment and single-family home radiators with limited installation space
Small offices and light commercial heating installations
Renovation projects where compact valve heads are required
Heating systems that require hydraulic balancing and temperature control
Key specifications
Thermostatic radiator valve set with compact adjustable head
Pre-setting function for flow limitation and system balancing
Designed for hot-water central heating radiators
Mini/low-profile thermostatic head for space-restricted installations
Automatic temperature regulation through thermostatic control element
How to use
Install the valve set on the radiator inlet according to standard plumbing practice, ensuring correct orientation and secure connections to the radiator and supply pipe. Set the pre-setting value on the valve body to limit maximum flow as required for balancing the heating circuit. Attach the mini adjustable thermostatic head and adjust the temperature setting by rotating the head to the desired level; the thermostatic element will modulate flow automatically to maintain the set room temperature. Commission the system and, if necessary, fine-tune pre-setting and thermostat positions to achieve uniform heating across radiators.
Usage recommendations
For best performance, use the pre-setting feature during initial system balancing and avoid fully closing the valve with the thermostatic head when room temperatures are low to prevent cold spots. Periodic inspection and gentle cleaning of the head and valve connections will help maintain reliable operation. If replacing an existing valve, verify compatibility of connection type and size with the radiator and piping before installation.
