Pneumatic valve RotaVal FDP

vacuumshaftfor the pharmaceutical industry

RotaVal’s range of two-way diverter valves has been developed to satisfy the needs of an ever more demanding market place, including the stringent requirements of the food and pharmaceutical industries, however they are also suitable for use in most other industries. Flap diverter valves are designed to route powders and granular materials within lean phase pneumatic conveying systems where the product handled does not exhibit abrasive or sharp irregular characteristics. The design embodies a self-adjusting parabolic flap seal. This bears on a fully machined surface to give excellent sealing characteristics. Care has been taken to ensure a minimal change in cross sectional area through the valve, thus reducing any contraction or expansion which can cause conveying efficiency losses. The valve housing is cast and may be of aluminium, iron or stainless steel. Shaft seals prevent product escape to atmosphere. The valve may be used in positive conveying systems at pressures up to 1 barg and in vacuum systems to -300 mbarg.
