A20 motorized valve low noise testing suit for sleeping environment
The low noise level motorized valve will placed in a mobile accommodation vehicle with sleeping people
Our engineer say there's 3 solution for low noise motorized valve.
1. Gear is changed into plastic and brass gear
2. Replace working voltage 3.5v + plastic and brass gear gear.
3. Replace working voltage 3.5v
This plastic gear, we do too high and low temperature impact, we also do the blocking test, the strength of the plastic is no problem.
A20 actuators, three gear instead of plastic gears(POM+brass),
do the following test no problem:
put motorized valve in - 15 ℃ + / - 5 ℃ 0.5 hour, later,
put motorized valve in 60 ℃ + 5 ℃ again, 0.5 hour
as a cycle, take 10 cyles, check product after test, the valve can be running well.
