We recommend you to choose a rotary valve with the inlet be \u2265100 mm. Additionally, a reinforced wear-resistant impeller should be selected. This will help avoid particle jamming or excessive wear of the impeller.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-335ef9d elementor-widget elementor-widget-text-editor\" data-id=\"335ef9d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>For materials with good flowability, such as cement, standard rotary valves can be chosen. However, for materials with poor flowability, you may choose rotary valves with stronger pushing capabilities. Options include stainless steel impellers with anti-stick coatings (e.g., 304 material). Alternatively, models with variable frequency drive functions can be selected. These can adjust the rotation speed to avoid material accumulation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b1ee595 elementor-widget elementor-widget-heading\" data-id=\"b1ee595\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">2.Site operating conditions <\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-20d6218 elementor-widget elementor-widget-text-editor\" data-id=\"20d6218\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Ambient temperature is an important consideration.
