LLC, WellMark, 1-1/2" 500WP, ST-2T-P

For use in low-pressure vessels or tanks, this versatile and multi-optional device can be used as a level control or as a component of Hi-Lo level alarm systems. The 1* MNPT unit may be mounted into a 1" coupling when the float is accessible from inside the vessel. If float is not accessible, a 2° or larger connection must be provided to allow passage of the float through the connection. The pneumatic 3-way 2-port no-bleed pilot valve makes this unit an excellent choice for the control of liquid level in oil and gas production equipment such as separators, dehydrators, treaters, as well as in manufacturing plants, hazardous waste disposal, food processing, petro-chemical facilities, or wherever fluid levels need to be monitored or controlled.
