Description
The Johnson Controls T-3111-1 is an integral thermostat and piston top valve actuator - the direct acting version with an external set point and bulb element.
The T-3111 is a combination thermostat and valve actuator providing proportional control of a steam or water valve on a single temperature application. Designed for use on a valve controlled terminal air conditioning unit. It fits any Johnson Controls 1/2 in. through 2 in. normally open, normally closed, or mixing valve which takes a V-3000 actuator, and valve top models are compatible with VG7000 Series valves. The instrument includes a protective snap-on cover.
Direct or reverse acting models are available with liquid filled temperature measuring elements to suit heating or cooling applications, and models are available with an external or concealed setpoint adjusting screw so the setting is field adjustable or concealed to maintain system design as commissioned. The dial pointer on externally adjusted models has tabs which are factory set to restrict the dial adjustment to a span of 15F° (7.5°F on either side of the pointer). Be sure each T-3111 thermostat has a 0.007 inch in-line restrictor installed in the supply air connection.
