Code No. LIT-1927330 Issued February 1, 2009 V47 Series Temperature Actuated Modulating Valve Description Features • no close fitting sliding parts in water The V47 is a temperature actuated modulating valve that regulates the flow of water or glycol passages to maintain a desired temperature. Three • range spring does not come in contact with temperature ranges for each valve size are the cooling water available. • easy manual flushing, if required • valve design minimizes chatter and water Many valves come with a removable bypass hammer plug that can be replaced by the bypass orifice provided separately with each valve. Valve action is open on temperature increase. For open on temperature decrease models, contact Application Engineering. V47 Series Valve Selection Chart Code Pipe Range Bulb Size, in.

Carefully follow the steps 2 as outlined below. 1 Determine the maximum water flow required. 100 379 Draw a horizontal line through this flow across the 90 1-1/2 349 80 303 upper half of the flow chart. 70 265 1-1/4 60 227 2 Use the following method to determine the 50 1 189 temperature rise above the opening point. 40 151 a Valve closing point is the highest temperature 3/4 30 114 at which it is desired to have no flow through the valve. 1/2 20 76 b Valve opening point is about 5F° above the Water Flow Water Flow closing point. Gal. / Min. L/Min. c Determine the temperature the valve is to 3/8 10 38 maintain, this is the operating temperature. 9 34 30 8 d Subtract the opening temperature from the 7 26 operating temperature. This is the temperature 6 23 5 rise above the opening point. 19 4 15 3 Determine the available system pressure for use with the valve by the following appropriate 3 11 method: 2 7 Open System: Available System Pressure = Inlet Pressure - condenser pressure drop - friction losses in piping. 3.8 Closed System: 36 2 50 2 10 Available System Pressure = Inlet Pressure - 5 20 30 40 (345) (14) (69) (34) (138) (207) (276) static head - condenser pressure drop-friction 30 -1 losses in piping. The available system pressure is represented by 60 Temperature Temperature the curve in the lower half of the flow chart. (414) Rise Rise -4 24 Above Above 4 In the lower half of the flow curve, draw a Opening Point Opening Point o o horizontal line from the temperature above the ( F) (C) opening point (Step 2d) to the available system 18 -8 pressure (Step 3). If the point falls between two pressure drop curves, use the curve to the left 12 -11 (this gives an automatic factor of safety). 5 From this point, draw a vertical line until it intersects the flow line from Step 1. 6 -14 6 If the intersection falls on a valve size curve, this is the valve size. 7 If the intersection falls between two curves, use 0 -18 the curve to the left for the required valve size.
