The plumbing valve, in simple terms is what you use to control the flow of water in a water system. A Bell &Gossett circuit setter valve is a type of balancing type valve which is commonly applicable in an HVAC or plumbing system to control and manage the pressure in the entire system or inside a part of the system.

In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems.

In baseball scorekeeping, a swinging strikeout is recorded as a K, or a K-S. A strikeout looking (where the batter does not swing at a pitch that the umpire then calls strike three) is often scored with a backwards K (ꓘ), and sometimes as a K-L, CK, or Kc (the 'c' for 'called' strike).

Full Opening Safety Valve or TIW valve is a ball valve designed for high pressure condition and it can hold pressure from both directions. It is called “Full Opening” because when the ball valve is opened; the flow path through the valve has a smooth inside diameter.

A thermostatic expansion valve (TXV) (see Figure 1) is a refrigeration and air conditioning throttling device that controls the amount of refrigerant liquid injected into a system's evaporator—based on the evaporator outlet temperature and pressure—called the superheat.

2 spool hydraulic valve is a device used to control hydraulic systems. ... The 2 spool valve consists of lands and grooves. The lands block oil flow but the grooves allow oil to flow around the spools and through the valve body.

The butterfly valve is a rotary valve in which a disk-shaped seating element is rotated 90° to open or close the flow passage. They are used in throttling service, particularly where large-size valves with automatic actuators are required. Butterfly valves cannot be used where a nonobstructed, full opening is needed.

The Suction Control Valve (SCV) is responsible for controlling fuel pressure in common rail engines. They move via a solenoid with each small incremental variation of the throttle. The Suction Control Valve uses extremely fine tolerances within their moving parts.

Tractor protection valve: The tractor protection valve keeps air in the tractor or truck if the trailer breaks away or develops a bad leak. The tractor protection valve is controlled by the trailer air supply control valve in the cab. The control valve allows you to open and shut the tractor protection valve.

Today, there are two major types of variable valve timing: cam phasing and cam changing. With cam changing, the ECU selects a different cam profile based on engine load and speed, whereas with cam phasing, an actuator rotates the camshaft, changing the phase angle.

If either check valve should leak, the relief valve is designed to open and discharge water to the outside. A properly functioning Reduced Pressure Backflow Assembly (RPBA) will periodically discharge small amounts of water due to fluctuation in line pressure up or downstream of the assembly.
