Thermostatic Radiator Valve Set INVENA IECD-74-P15 with Mini Adjustable Head and Pre-setting

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.
