Pre-Insulated Butterfly Valves – Energy Efficient & Ready-to-Install Solution Advance Pre-Insulated Butterfly Valves are designed to deliver superior performance in HVAC and industrial piping systems while significantly reducing on-site insulation work. These valves come factory-insulated, saving installation time, labor costs, and ensuring consistent insulation quality across the system. The insulation material used is Polyisocyanurate (PIR) with a density greater than 70 kg/m³, making it highly efficient for thermal insulation. It is suitable for a wide operating temperature range from -40°C to 120°C, ensuring reliable performance in both chilled water and heating applications. The PIR insulation is protected with a durable HDPE cladding, which prevents physical damage, moisture ingress, and peeling, thereby extending the life of the insulation. From a safety perspective, the insulation meets Class P fire performance standards as per H5476 Part 5, with low flame spread and self-extinguishing properties. This enhances fire safety in critical installations. Additionally, options for aluminium or HDPE cladding are available based on project requirements. A key design advantage is that the insulation fully encloses the valve body while allowing standard flange connections. Bolts can be tightened directly on the metal flange surface without affecting insulation integrity, ensuring easy installation and maintenance. Valve Range: Concentric Butterfly Valves Sizes from 50 mm (2”) to 600 mm (24”) Available in Manual and Motorized configurations These pre-insulated butterfly valves offer a cost-effective, energy-saving, and hassle-free solution, making them ideal for modern HVAC systems, district cooling networks, and industrial applications where efficiency and durability are essential.
