Is it possible to sort the post based on a custom field?

I have a custom field called "value_date" where I enter a date e.g 20/04/2017

The idea is sort the upcoming dates first in the loop, is possible?

I used a template for custom post taxonomy-event-date.php


    <!-- // The Query // -->
    <?php
    if( have_posts() ) {
    $alt_post = 'alt-post';
    while( have_posts() ) {
    the_post();
    $alt_post = $alt_post == 'alt-post' ? '' : 'alt-post';
    ?>
    <div class="box-page-shows-block">
    		<?php
    		global $wp_query;
    		$postid = $wp_query->post->ID;
    		echo get_post_meta($postid, 'value_date', true);
    		wp_reset_query();
    		?>
    </div>
     <h2><?php the_title(); ?></h2>
    		<?php
    		}
    		}
    		?>
