Important Tips For Using Safety Valve of Electric Water Heater
1stly, check the pressure of old safety valve you use or the nameplate of heater. If the rated pressure is 0.8MPa, then choose the safety valve with pressure 0.8MPa.
And if the pressure range is 0.75Mpa, the water tank’s volume must be less than 50L.
If the pressure range is 0.8Mpa, the water tank’s volume could be 50-80L.
If the pressure range is 0.9Mpa, the water tank’s volume could be more than 50L.
2ndly, the valve must relief the pressure in high precision. That means when pressure exceeds the set value, the valve must release the pressure sensitively. The precision of BESTJADES VALVE can be controlled within ±0.2bar .Even the valves can meet above requirements, it is still not enough. BESTJADES offers you more better solutions.
To avoid any backwater leakage problem, it adopts double sealing and non-return structure and make sure the water go in 1 direction to avoid the hot water back to the pipe.
To help end users to resolve the problem of non working under low pressure, it adopts the Japan imported stainless steel spring which make the better resilience and the valves can be started at low pressure. When the inside pressure difference exceeds 2bar±0.5bar, it will start to adjust the pressure.
