Bronze thermal circulation valves, PN16.
Application
Suitable for domestic hot water systems to assist with protection against Legionella.
Description
Bronze thermal circulation valves, PN16.
Features and benefits:
- Ideal for domestic hot water systems to assist with protection against Legionella.
- Provides self-balancing, thermostatically controlled regulation of flow and disinfection.
- Thermal disinfection at temperatures above 70°C.
- Compact unit comprising isolation valve with thermometer access point.
- Incorporates a settable temperature sensing cartridge, factory pre-set at a standard 57°C.
- Has an accuracy of +/- 2°C at set temperature.
- WRAS Approved.
Operation:
- When the set point is preset to 57°C, the valve remains completely open up to a valve temperature of 52°C.
- Between 52°C and the set point of 57°C, the valve starts to close.
- When the set point temperature has been reached, a minimum volume flow is continuously flowing through the circulation system.
- If the storage temperature is further increased to temperatures greater than 70°C to effect disinfection, the valve increases the flow.
