AVG Reverse Non Return Valve High Temperature Solar - NVHT-15F-15C
AVG has developed a range of valves for solar applications and in collaboration with the solar hot water industry has developed a high temperature non return valve. As solar hot water heaters are becoming more efficient and the stagnation temperatures within the solar collector panels is increasing, damage to pipework and other components is becoming an issue. The HTCV is a high temperature non return valve designed to prevent the back flow of high temperature hot water. The "Reverse" model for your convenience has had the check valve reversed so that the direction of flow is from the 15mm compression connection of the valve. The NVHT would typically be installed approx. 500mm above the solar circulator pump, please check with manufactures installation requirements for your system.
- Robust DZR brass construction
- Designed for high temperature solar installations
- No plastic internal components
- High temperature internal components
- High temperature silicone seals
- Reversible check valve cartridge
- Two HTCV models are available with alternative flow directions
- IMPORTANT NOTE: check the flow direction on the data ring before installing
- The HTCV is suitable for vertical or horizontal installations
The NVHT-15F-15C has a DR brass body with RP 1/2" Female X 15mm compression end connections to comply with the requirements of the Australian standards. The body which houses a high temperature non return valve assembly is capable of withstanding temperatures up to 250°C. As solar hot water heaters are becoming more efficient the stagnation temperatures within the solar collector panels are becoming an issue with modern plumbing systems. High temperature non return valves need to be installed to prevent heated water from the solar collector panel from damaging plastic water pipes, pumps, valves and other components installed within the plumbing system. The NVHT-15F-15C is suitable for any situation where the plumbing installation calls for a non return function. The valve can be installed in any orientation.
High temperature non return valves need to be installed to prevent high temperature hot water from the solar collector panels damaging plastic water pipes, pumps, valves and other components within the plumbing system. This valve is suitable for pumped solar flow and return lines to prevent back flow.
The valve can also be installed to prevent back flow and damage to the plastic cold water pipework, the HTCV can be installed into the incoming mains supply line to a storage hot water heater.
