These valves are often used to limit flow to a fixture. Maric Flow Control valves maintain a fixed, pre-set, constant flow rate, regardless of pressure. A valve is a device or natural object 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. Water must be flowing through the heater at the minimum rated flow rate during operation. Resource Library. Control valves are normally fitted with actuators and positioners. Most flow controls have a hand operated flow control, others have a cross handle that is turned using a tool (pliers will work if you don’t have the special valve … A heavy-duty, rugged pinch mechanism positions the sleeve, resulting in accurate flow control. Red Valve Control Pinch Valves offer maximum durability with precise control and virtually no maintenance.
