Its inclined blade forms an eye-shaped aperture with the asymmetrically tapered inner body. The wider the eye is opened, the more material flows through, the further it is closed, the more the material flow is reduced. The inner body consists of a self-supporting cast in SINT® engineering polymer composite. The blade is manufactured from carbon or stainless steel. The Valve can be operated manually, electropneumatically or by gear motor. Intermediate blade positions instead of a complete opening are obtained through position sensors and made visible by an external indicator. To enforce material flow at low flow rates the dustproof VDI Valve can be equipped with an additional pneumatic hammer that imparts repetitive percussions to the internal valve body during operation.   Function The VDI Inclined Slide Valve adds to the simple function of material flow by gravity interception the ability to control the material flow. The particular asymmetrical geometry of the blade enables flow adjustment adding, within certain limits, volumetric feeding properties to the unit. VDI Valves can be mounted on the outlets of hoppers, tanks, silos, screw conveyors, and loading bellows. Due to the different blade options they are used in virtually every industry, food-grade applications included.   Performance & Technical Features - Benefits Body in carbon or stainless steel lined and coated with SINT® polymer composite Interchangeable blades in carbon steel, stainless steel or SINT® engineering polymer Interchangeable actuators: manual, pneumatic or gear motor SINT® engineering polymers for standard or food-grade applications Intermediate blade positions for feeding Dustproof design Highly abrasion-resistant Ex-stock delivery   Options & Accessories CMG-type hand wheel actuator (see page) CRG-type gear motor actuator (see page) FDA-approved food-grade version » More info
