The key word is "drain", meaning it works by gravity, so a drain value should be at the lowest point in the system. Typically there is one just past the meter.
If a lawn irrigation system is a branch of the main system it should have its' own drain valve for winterizing it.
You can purchase stop valves (or shutoff valves) with built-in drain or bleeder valves.
The EJ25 series engine fitted to the 2012 Subaru Forester has 16 valves.
This is a common complaint with mk2 Golfs, most of which were fitted with a heater matrix bypass valves to prevent the heater matrix from bursting under certain conditions. These bypass valves can fail, cutting off supply to the heater matrix resulting in no heat. Either replace the valves or remove them and fit a heater matrix from a mk3 Golf. These are stronger units and don't require bypass valves.
were the hydraulic cam followers changed with the valves if not, that is the problem.
I'm not famiar with the Grundfos valves specifically, but non-return valves are usually fitted to the suction side of pumps to prevent the pump from losing it's prime when it is stopped (by draining back through the inlet).
Deluge valves are hydraulically operated differential type valves used to control water supply to a deluge system. Deluge systems use open sprinklers or nozzles. Trim sets are used to control the operation of the valve.

Valves are found in the heart and in some veins.
Veins contain valves preventing blood from circulating backwards.
Cylinder head where valves are-usually. Valves themselves, no. Antifreeze passes around the engine in special chambers known as galleries. It cools the metalwork of the engine and does not (or should not) enter any part of the combustion, or intake system.
All showers need valves. They can be for the water supply, balancing the water and control of the shower. Without the valves, your shower will leak, causing damage to the surrounding areas.
The valves keep blood flowing in one direction. And there are even valves in the veins. The system is called a circulatory system and the system must keep going in a circle to function properly.
Sprinkler systems can use many components that control the flow of the water. A plastic piping connects the water supply to the electric valves and the sprinkler.
