'''Dual Cylinder Roller Gate''' is specifically designed to handle dry material in gravity flow and low pressure applications where positive material shut-off and a dust tight seal are required. Traditional knife gates or dual cylinder gates rely on soft rubber seals, which erode or tear away during use, allowing leakage of air and material through the valve or into the atmosphere. This causes the frequent need for valve maintenance, production inefficiencies, and unsanitary plant environments. The dual cylinder roller gate is designed to eliminate these problems, enabling you to meet your objectives by increasing production, while decreasing labor and equipment costs and are available in a wide variety of configurations, including rectangular sizes and round inlet or outlet transitions. | |||

* | ==Features== | ||
* Dual cylinder roller gate comes with live loaded wear compensating seals that prevent material from escaping into the bonnet area of the gate. Standard removable seal access ports allow for replacement of the seals if required. | |||
* Dual cylinder roller gate utilizes easily accessible, nylon cam-adjustable rollers instead of blade guides in the opening of the valve. This feature is critical in preventing material packing, which causes the valve to seize and wear prematurely. | |||
* Dual cylinder roller gate features full stroke polymer blade guides which eliminate blade racking and promotes smooth actuation. In addition, the polymer liners eliminate metal on metal contact and associated seizing, binding, and foreign material contamination. | |||
==Applications== | |||
Dual cylinder roller gate is designed specifically for handling dry material in gravity or low pressure applications where a dust tight seal is required. The dual cylinder roller gate can be applied to shut-off or meter the flow of fine and moderately abrasive powders and small to large granulars or pellets. Adapting the dual cylinder roller gate to the system requirements is made easy with a wide selection of [[Actuators]], gate positioning controls, position indication [[Switches]], and [[Flanges]]. The dual cylinder roller gate also offers a wide variety of modifications to accommodate high or low temperatures, corrosive, humid, and explosive environments. | |||
