How to give default value for numeric slider(It should not be random)?

I have a code for numeric slider. I am able to give min and max value for the slider, but I am not able to specify specific value as default when the page is loaded. I am able to give random value but I want it to be fixed value as we give as value="number".

I have plan to fetch the default value for slider from database. So please let me know the ways to give it in html tags only.

Use ng-init to set the default value to disabled1 scope variable. See JSBIN

<div ng-controller="AppCtrl" ng-init="disabled1=10" ng-cloak="" class="sliderdemoBasicUsage" ng-app="MyApp">
  <md-content style="margin: 16px; padding:16px">
    <div style="margin-top: 50px;"></div>
    <md-slider-container>
      <md-icon md-svg-icon="device:brightness-low"></md-icon>
      <md-slider ng-model="disabled1 " aria-label="Disabled 1" md-discrete="" min="1" max="50">
      </md-slider>
      <md-input-container>
        <input type="number" ng-model="disabled1" value="17" min="1" max="50" aria-label="green" aria-controls="green-slider">
      </md-input-container>
    </md-slider-container>
</div>
