flow restrictor
Loosen the nut on top. Tighten the screw clockwise to increase, counter-clockwise to decrease pressure. Tighten the nut back up. Done deal
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
To correct the pressure in water pipes, you can adjust the pressure regulator valve. Locate the pressure regulator valve, which is typically found near the main water line or near the water meter. Using a wrench, turn the adjusting screw clockwise to increase the pressure or counterclockwise to decrease it. Be cautious not to exceed the maximum recommended pressure for your plumbing system.
To regulate the pressure to a pre-determined amount.
Pressure safety valve-are the valve who are designed such that it can control the pressure , like in the water blowers etc,and Temperature safety valve are those who are used to regulate the temperature like, in water boilers.
There is no such thing as a valve cannot increase or decrease pressure IT can throttle volume or stop the flow.=One would need a pressure booster pump to increase pressure=
Yep.
The function of air valve of sphygmomanometer is to decrease or increase the airflow into the cuff. It is necessary for an accurate blood pressure.

With a pressure reducing valve to get to the desired setting you need.. Watts and B&G make decent products
Not noticeably unless the valve is partially closed.
Pressure reducing valve reduces the pressure of fluid upto a predetermined pressure in this case downstream pressure will be obviously lower than upstream pressure but in case of pressure regulating valve it will regulate the pressure( either increase or decrease) depending on the requirement of system at that time.
You close the valve a little. -If that is not what you wanted, then please explain more next time.
I am assuming that you are talking about a wall hung urinal! Most urinals have a mounting bracket where the urinal seals against the drain line. There is a soft foam gasket that makes the seal between the urinal and the drain line. First, secure the water to the urinal, remove the flush valve, there are usually 2 screws or bolts located on at the bottom of the urinal, unscrew these and remove the urinal from the wall, replace the gasket and then replace the urinal in the reverse of removing.
Pressure Differential Valve- maintains a constant Differential pressure across it. Say if P1 was inlet pressure and P2 was outlet pressure PDV will try to keep constant DP. Say if P2 increases due to some reason and P1 is constant the DP will decrease and will decrease flow through the PDV. At this point to maintain the constant DP PDV will open and allow more flow through to keep the flow constant and thus DP constant.
To the right for more pressure To the left for less
Depends on the make of flush valve. Some have a screw under the cap that you turn clockwise to increase, counter-clockwise to decrease the pressure. Best thing to do is change the diaphragm and go from there.
