	membraanklep		een klep waarin de vloeistof direct door de klep loopt via een kamer waarover een diafragma is aangebracht. Dit diafragma is normaliter zo aangebracht dat het geen weerstand vormt voor de stroom.

	diaphragm valve		a valve in which the fluid flows straight through the valve via a chamber over which is an elastomer diaphragm. This diaphragm is normally arranged to provide no resistance to the flow. The perimeter of the diaphragm is simply clamped to a seal face of the valve body like a static seal. To close off the valve the diaphragm is simply forced down into the chamber to block off the flow. The chamber can include a weir across the flow path against which the diaphragm can be pressed to affect a more efficient seal with reduced diaphragm distortion. Diaphragm valves are manufactured in sizes from 6mm to 400mm, generally limited to relatively low fluid pressures (less than 7 barg). However in the smaller sizes (up to 50mm) valves can be especially engineered for use at pressures up to 30 barg. The diaphragm must be compatible with whatever fluid is used, the diaphragms must be replaced at regular intervals and it is advisable to operate the valves frequently. These valves are often used for duties which require a high degree of cleanliness, and they can be supplied lined and polished, and can be very conveniently cleaned.
