The 33D is a full port, 3-way, 316 stainless steel, NPT threaded multi-port valve. It can be equipped with a manual handle or with direct mount pneumatic or electric actuators. The direct mount actuators eliminate the valve-actuator mounting kit, which adds unnecessary height and expense. This valve is ideal for diverting flow to two destinations or receiving two different products into one vessel.  Available in line sizes of 1/4" to 2".

A full range of accessory items are available including limit switches, solenoid valves, positioners and manual override devices

When purchasing 3-Way Ball Valves, use Assured Automation's online configurator to quickly and accurately select the valve assembly that meets your unique needs. The configurator allows you to specify and verify port arrangements for "L Port" and "T Port" valves. For example, to select a "T Port" valve configuration, select one of the five flow plans from a visual cross-section diagram to ensure proper flow paths.
