Parker P32S Series global compact soft start valves offer 2-way, 2-position functions for safe introduction of pressure to machines & systems, thereby preventing damage. They permit pressure to gradually increase on initial set-up points before fully opening to deliver full air line pressure. The integrated needle valves in the covers adjust ramp-up time to reach switch over-pressure. These electromechanically operated valves have a modular design with 1/2 inch integral ports to allow fluid to pass through.
