Does the expansion valve provide a fixed size restriction?
Expansion valves aren't valves. They're called an Orifice Tube because they're a fixed size hole. The hole creates a drop in pressure from the high side of the air conditioning to the low side. Is this true? As necessary, the hole gets smaller and larger.

Do valves open clockwise?
The best way to open a gate valve is to gently turn the handle to the left, without applying excessive force. The main control valve for a water line takes about six full turns to fully open.
Are valves closed at top dead center?
There is a power stroke. The spark plug has just fired and the intake and exhaust valves are both closed. Is that correct? The exhaust valve starts to close. The exhaust valve is partially open when the intake valve starts to open.
Is valve adjustment necessary?
The valves won't fully close if you wait too long. The trouble starts there. They recommend a valve adjustment for older models. They recommend just listening for noise and adjusting when necessary for newer ones.
