Feeders & Valves An integral part of many powder handling systems is the “feeder” or valve to provide the controlled feed of product into the process. IEDCO is proud to be the Exclusive North American distributor for MEI Valves (pronounced “May”).

MEI Valvole Industriali has been a leading Italian manufacturer of valves and valve accessories for the past 20 years. Today they have a company with avant-garde technology and an innovative spirit. MEI Valves are currently being used in the Pharmaceutical, Chemical and Food industries throughout the world.

Technology and innovation, together with the extensive experience of the founders, have contributed to the constant expansion of the company and acquisition of new sectors of the market. "Quality in service and in product" is the motto of MEI Valvole Industriali, and their high standards are easily seen in their accurate, consistent and efficient valves.

Unlike other valve companies, MEI designs and manufactures all their valves 100%. This allows them, and us, to offer their highly accurate valves at an extremely competitive price versus their competitors.

Butterfly Valve The BUTTERFLY VALVE sets the standard in hygiene and cleanliness for the handing of powders, granules, pastes, liquids and gases in the hygiene conscious industries.

The BUTTERFLY VALVE offers superior quality coupled with the latest design and technology available for a butterfly valve.

The product range also includes connection systems between different processes. Sealing against pressure and vacuum - Quick release by "CLAMP" - Very light and thin - Available with manual handle or with pneumatic actuators in sizes from 4” to 12” with standard sanitary ferrule connections.

Rotary Valves The ROTARY VALVE allows continuous feeding of granules and powders without flow obstruction. Its use is ideal for feeding of: mills, tablet press machines, capsule filling machines, microdosing machines, sieving machines. A 6 pocket rotor (8 on request) turns back and forth introducing a uniform quantity of product.

The ROTARY VALVE’s unique design provides a flow control system in far less space and with smallest dimensions than conventional star valves.

The ROTARY VALVE has been developed to provide uniform dosing of product. Its star configuration and its movement (alternating 180 degrees in one direction and 180 degrees in the other direction) supplies product and transfers it into the machine below by keeping above that contained in the feeding receiver. The reciprocating movement prevents separation. The operation of the valve movement can be regulated as required and, with the proper controls, can be used as an accurate batch feeder.

Tablet Valve The TABLET VALVE offers an ideal solution for handling capsules, tablets, pills, silicone caps, etc...

Its silicone coated disc allows opening and closing of the valve without any damage to the product The TABLET VALVE vane is silicone coated and its outer surface is flexible. This allows opening and closing of the valve without damaging the product. The silicone is of medical grade material based on the standards of Pharmacopeia FDA 21 CFR 177.2600.

IEDCO IEDCO Universal Tablet Feeder Shutting off or valving against pharmaceutical tablets or fragile food products can be a challenge, for fear of damaging the product. Controlling the flow of these products to produce an accurate batch can be even more of a challenge. To deal with this challenge, IEDCO has developed their Universal Tablet Feeder.

Very simply, our valve attaches to the bottom of a hopper or vessel that contains the tablets, via a tri-clamp connection. A ferrule is used to clamp a length of poly tubing, which extends down through a ring. This ring is mounted on a spring-loaded rotary actuator. The valve is spring loaded closed, or with the ring in the vertical position, thereby choking off the flow of tablets through the poly sleeve. When actuated, the ring rotates 90 degrees, permitting the flow of tablets through the ring and the poly sleeve. By controlling the tablet valve with a repeat timer the actuator can be “pulsed” providing very accurate feeding and batch control.

The design provides for the completely safe handling of fragile tablets, candy or other products, as there are no pinch points. It is completely hygienic and the poly sleeve is, of course, disposable.

IEDCO’s Universal Feeder Being prejudice against things that rotate and are hard to clean, IEDCO has developed a feeder system we call our Universal Feeder. For more information, please refer to our Universal Feeder Brochure.

An integral part of many powder handling or multi-ingredient batching systems is a “feeder” or a device, which permits the controlled feed of product into the process, whether it is on a volumetric or gravimetric basis. Traditionally, batch feeding has been accomplished by either vibratory feeders or screw feeders. Vibratory feeders are relatively hygienic but performance is limited to fairly free flowing materials. Screw feeders are inherently difficult to clean and have bearings and motors, making them relatively high in maintenance.

IEDCO’s Universal Feeder allows for accurate batching of otherwise difficult profducts. However, we have also successfully achieved batching accuracies of +/- 0.00 kg using the MEI Rotary Valve (as seen on the opposite page).

The Universal Feeder System We didn’t invent the pinch valve, but we are very grateful to whoever did. A pinch valve is a very simple and sanitary valve, which incorporates a food grade rubber bladder in a housing. It is a full bore valve and when compressed air is applied to the housing, the bladder pinches off the bore and closes the valve. When the air is released the valve opens. By pulsing the valve with a set of repeat timers, batch accuracies of 10 grams or better can be achieved.

The sanitary valve we use has a unique one-piece sleeve design, incorporating tri-clamps integral O-ring seal molded onto the sleeve ends. The design makes this sanitary valve a straight through port design, eliminating crevices and dead spots, in order to reduce the possibility of bacteria. The key to this valve is in the flexible food grade rubber sleeve, the valves only wetted part.

Actuation of the valve, the pinching action, is accomplished by air placed upon the sleeve. The valve body acts as a built in actuator. Adding pressure within the annular space between the housing and sleeve can throttle or close the valve.

The sleeve’s flexibility allows the valve to close "drop tight" around entrapped solids, eliminating hang-ups. When the valve is open, it is like a straight piece of pipe in the line.
