ESBE VRI111 DN25 Insulation Shell for VRG and VRB Valves

Description

Improve the thermal efficiency and safety of your heating system with the ESBE VRI111 DN25 insulation shell. Designed specifically for compatible ESBE rotary valves, this precision fitting EPP shell helps reduce heat loss, limit air circulation around the valve and protect against contact with hot surfaces.

The self locking two piece design provides quick installation without the need for tape, springs or additional fastening accessories. It is suitable for heating, underfloor heating, potable water, solar heating, ventilation and zone control applications.

Key Features

Reduced Heat Loss

Helps reduce heat loss by up to 65% compared with an uninsulated installation.

Made for ESBE Valves

Designed for compatible ESBE VRG100, VRG200, VRG300 and VRB100 valve series.

Secure Self Locking Design

The shell holds together securely without requiring tape, springs or separate fixing accessories.

Heat Resistant Construction

Suitable for media and ambient temperatures from -20°C to +130°C.

Lightweight EPP Material

Manufactured from black expanded polypropylene with a thermal conductivity coefficient of 0.035 W/mK.

Helps Improve Safety

Encloses the hot valve body to help reduce the risk of accidental contact with heated surfaces.
