Description

Fig. 2910 Thermal Circulation Valves

Features & Benefits
• Anti-stagnation design ensures a clean flow path, minimising fluid entrapment and the
growth of bacteria
• 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
• Available in size DN15

Material Specification

• Bronze

Pressure/Temperature Rating

• PN16
• Max Temperature 90°C

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.

Specification

Taper threaded to BS EN 10226-2
