TP valve PT valve for solar water heater temperature and pressure release
T/P Valve
1, Commodity name: Temperature and Pressure Relief Valve
2, Use:P/T Valve for solar water heater, electric heater and so on
3, T&P relief Valve Function:
The T&P valve is designed to relieve the increase in pressure
which develops during the normal heating cycle.
This is caused by the water expanding during the heating cycle.
The T/P valve then will relieve the increase in pressure by releasing drips
of hot water to the drain line. It is recommended
that an expansion control valve be
fitted to the cold water supply line as it will relieve cold water(not hot water),during the heating cycle expansion,thereby saving
energy and increasing the life of the T&P relief
valve.Local regulations may make it mandatory to install an expansion
control valve in the cold water supply line.
4, T/P relief valve for solar water heater
Inlet pressure control:
High pressure may cause excessive discharge and possible premature
failure of the operating relief valve.
The maximum water pressure usually occurs during the night, at the time of lowest water
usage. In any mains pressure
water heater installation,if the inlet water pressure exceeds 80% of the nominal set pressure
of the operation relief valve,a pressure limiting valve must be fitted to the cold inlet.
5,T&P Valve Installation:
T/P Valves should be installed by a licensed plumber.
If the temperature probe protruding from inside the inlet thread is damaged or bent,do not
install,and obtain a replacement valve.
