Product Description:

• Modern control valves may regulate pressure or flow downstream and operate on sophisticated automation systems. As the pressure below the disc increases, it rises up from the seat to prevent the flow. The valve closes with a drop in pressure on the inlet side and a buildup of pressure on the outlet side. The disc is held in closed position owing to the back pressure in the line.
• A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The simplest, and very ancient, valve is simply a freely hinged flap which drops to obstruct fluid (gas or liquid) flow in one direction, but is pushed open by flow in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction.
• Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on/off and pressure control to dish and clothes washers and taps in the home. Valves are also used in the military and transport sectors.
