First step is checking the main pressure.You need more pressure to open the valve to go down,to go up the circuit is free,thats why is faster.Certainly you have to calibrate the valve block.
The other movements are good?
Let me know.

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
