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.

• 2.Technical Parameter

·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.

·Dimensions/Weights

• 3.How to Installation

·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.

 

Direct Installed on the Top Direct Installed in the Side

• 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.

Sapphire Crystal

Sapphire glass
Sapphire crystal has a crystalline rather than a glass-like structure. Sapphire has a Mohs hardness of 9, which is the third hardest of all transparent materials after Moissanite and diamond, so it is particularly valuable in this application because of its scratch resistance. Sapphire crystal is a high-purity synthetic sapphire (single crystal) made of fused alumina. The chemical formula is Al2O3, and the sapphire crystal is corundum.
Compared with traditional quartz glass or mineral glass, sapphire glass is slightly less sensitive to impact, and has a very high light transmittance and refractive index.
The physical properties of synthetic sapphire crystals:

Hexagonal crystal structure
Density: about 4 g / cm³
Melting point: +2050℃
Thermal conductivity at 25℃: 42 W/(m·K)
Compressive strength at 24°C: 2GPa
Tensile strength at 24°C: 186.4 MPa
100% acid resistance
