Description
The Johnson Controls T-3311-2 is a combination pneumatic thermostat and valve actuator for dual temperature, dual pressure applications: direct acting at 20 psig and reverse acting at 15 psig, with a bulb element, external set point and valve top mounting.
The T-3111 and T-3311 Series controllers are combination pneumatic thermostats and valve actuators. The T-3111 provides proportional control of a steam or water valve on a single temperature application, while the T-3311 provides control in dual temperature, dual pressure applications. Models are available in direct-reverse acting or reverse-direct acting, which allows seasonal change over from cooling to heating or heating to cooling automatically. Valve top models are compatible with VG7000 Series valves.
The adjusting dial is graduated in 1F° increments and 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); the restriction can be changed to 20, 15, 10 or 5 F° spans by bending up the appropriate tabs and flattening the factory set tabs. To replace the actuator diaphragm, the thermostat is removed from the integral actuator and a new V-3000-600 diaphragm fitted over the piston.
