The control of fragile products such as capsules and tablets, pearl drops or plugs made of rubber or silicone, does not allow for the use of traditional butterfly valves, as these products may be damaged when the valve is opened and closed. For these applications, the Flexivalve is recommended. The Flexivalve is a special butterfly valve with a flexible silicone coated disc and a soft seat that permits the control and isolation of the product flow without damage.
