| Green Top Control and Indication Unit |
Application To accommodate the trend towards custom control needs, an optional control housing module is available for our butterfly valves and our 700 series valves in place of the standard visual valve position indicator. Working Principle The top is fitted on the valve actuator. An extension attached to the actuator piston moves up and down with the valve movement. This movement is then seen by the position sensors and a digital signal is sent back to the PLC control system. Standard Design The control module is designed for fast assembly and disassembly. It can be mounted at either end of the actuator to accommodate normally open or normally closed valves - with no internal modifications to the actuator assembly needed. It’s compatible with either long-stroke or short-stroke actuators. Constructed from durable, glass-reinforced Nylon 12, the control housing is manufactured to stand up to the most punishing environments. It meets the NEMA 4 rating against leakage. Specially molded gaskets guard against leakage and breakdown, so the housing can be installed in any position. Additional application versatility can be achieved by specifying a solenoid in the control housing. This transforms the valve into a solenoid operated air valve with integral flow control. The module will then provide valve position feedback through your choice of mechanical switches or proximity switches. Options  |  | Housing is designed to accommodate a variety of switch options, including
proximity or mechanical
switches. | Control Top can also be fitted with a 3-way/4-way solenoid with integral flow control. |
Enclosure Rating NEMA Type 4 - Enclosures are intended for use indoors or outdoors to protect the enclosed equipment against splashing water, seepage of water, falling or hose-directed water, and severe external condensation. | Mechanical Switch |  | SPDT

| There are seven different sections to a standard part number. The part number sections will identify the valve and control top options and function. Each valve assembly has its factory original serial and part number printed on an identification label located on the actuator. | Valve Type | 1 | 741, 761, 762, 771 | | Body Style/Port Configuration | 2 | Refer to Valve Service Manual | | Actuator Type | 3 | Refer to Valve Service Manual | | Size | 4 | 1" through 4" | | Material | 5 | 316L | | Switch / Solenoid Option | 6 | See Chart Below | | Setup Option | 7 | See Chart Below |

The SWITCH / SOLENOID chart identifies what type of electrical components are to be utilized in the control top module. There are three standard solenoid voltages and three options for switch/sensors to select from. For any combination there is an option code ranging from 02 through 45. | | No Solenoid | 24VDC Solenoid | 110 VAC Solenoid | 24 VAC Solenoid | | Mechanical [VAC/VDC] | Quantity 1 | 02 | 14 | 16 | 39 | | Quantity 2 | 04 | 18 | 20 | 40 | | | | | | | | | | | | | No Switches/Solenoid Only | - | 37 | 38 | 45 |

The SET-UP NUMBER SELECTION charts define how the control top module is configured. There are up to seven different ways that it can be setup, but depending upon valve type and body style the operation can differ. Knowledge of the complete valve model is required to choose between the two charts. Chart A applies to Shut Off or Divert valves and Chart B applies to Reverse Acting and Kettle & Elbow tank outlet valves. | Chart A | | Actuator | Description | Set-Up # | | 19, 29, 39 | No Solenoid, normally open or normally closed valve | 1 | | | | | 29 | Normally closed valve opens when solenoid is deenergized | 3 | | | | | 19 | Normally open valve closes when solenoid is energized | 5 | | | |
