BAILEY 716T PRESS and TEMP RELIEF VALVE 40
The 716T protects unvented hot water systems, against both excess pressure and excess temperature. Increasing pressure is sensed by the spring, which automatically opens the relief valve at the pre-set pressure and the integral probe independently monitors increases in temperature, safely opening the relief valve between 90oC and 95oC.
The temperature probes are designed to have a smooth surface free from crevices, to reduce mineral build-up and are white powder coated to minimise galvanic action within the heater.
The 716T has a bronze body, DZR brass internals and silicone seat in accordance with potable water code requirements. A soft seat provides leak tight operation. The spring and spring chamber are protected from the hot water by the EPDM diaphragm, reducing corrosion and increasing life in service.
Valves are certificated prior to despatch to confirm traceable serial number and set pressure.
