solar water heater temperature and pressure safety valve
Designed and checked Based on American “ANSI Z21.22” Standard.
Temperature and Pressure Relief Valves is suitable for Installing
at the Pressurized solar water heater, gas heater, electric water
heater , water heater of fuel, heat pump water heater , sensitive
function heater, etc. various kinds of heaters( such as the boiler)
and hot water containers . The valve will be opened at the set
temperature and pressure to protect the water tank.
·Set Pressure(Psi): 75,87,100,125,150psi (0.5,0.6,0.7,0.8,1.0MPa)
·Set Pressure Tolerance: +5%,-10% of the set pressure.
·Set Temperature: From 65°C to99°C. (As you’re required)
·Set Temperature Tolerance: 99°C-5°C; other set Temperature is ±5°C
PS: We can made different type of valves as you’re required.
·Temperature and Pressure Relief Valves should be installed on the
top of the water heater top or side. The Temperature sensing
element must be immersed in the water within the top 6″of the tank.
·The eliminating pipeline should be installed under the relief
valve. Its terminal station distance in floor drain should be
greater than 6″to make it easily remove and observe water.
• Install drain piping to avoid contamination of the tank
surface.Drain pipe should be connected to floor drain or collector.
• When connecting the drain pipe, make sure that we can observe the
drain.The drain pipe should be well protected against freezing and
leakage, keep it clear and prevent blockage.
• A water pressure rregulator valve must be installed in the hot
water system to prevent sudden increase in water pressure and
affect the normal operation of the safety valve.
• Periodic inspection,the safety valve handle is swayed at least
once a year, water leaves the handle and back to its original
position,no water to indicate that the valve is invalid,it should
be replaced immediately.
• Dirt will directly affect the operation of the valve, please use
a clean water supply.Hard water areas need to increase the number
of regular inspections.

- 4.How to Safeguard And Maintenance:
·After installing water heater the users must lift the relief valve
handle once at least every year, so as to ensure that unblocked
things in the waterway of the relief valve.
·Before operating handles, please check the elimination pipeline
which joining the relief valve, guaranteed that the hot water from
the relief valve discharge the proper place, otherwise it may cause
the bodily injury.
·If the handle is lifted, without water flowing out, it proves that
the relief valve is invalid. Then it should turn off the water
heater immediately and check the valve.
- 5.Warranty time:12 Months.
