If you have formView object, you can render it using Twig function:

{{ form_widget(formView._token) }} 

If you haven't - you can render token without using form object directly:

Works in Symfony 2.x and 3.x

To validate the token you can use the following code in your controller (Symfony 3.x):

$submittedToken = $request->request->get('token');

if ($this->isCsrfTokenValid('some-name', $submittedToken)) {
    // ... do something,
}
