Overview
The Johnson Controls V50AE-2C is a 2-way, 1-1/4 inch self-operated modulating valve designed to regulate gas flow to maintain a desired air drying temperature. It functions as an operating device, utilizing a vapor pressure sensing element that opposes a range spring to increase gas flow on temperature drop and decrease it on temperature rise.
Features
- Free movement of parts provides fast, uniform response
- Easy to adjust by turning the T-handle range screw on top of the spring housing
- Equipped with high-temperature diaphragms as required for most LP gas units
- Built-in temperature gage available to indicate sensed air temperature
Specifications
- Valve Size: 1-1/4 inch
- Temperature Range: 90 to 210 degrees Fahrenheit (32 to 99 degrees Celsius)
- Maximum Line Working Pressure: 30 PSIG (207 kPa)
- Capillary: 15 feet armored capillary
- Bulb Dimensions: 11/16 x 17-7/8 inches
- Flow Coefficient: 11 Cv
Applications
- Specifically designed for outdoor crop dryer service to control natural or LP gas flow
- Commonly utilized on portable grain dryers and storage grain bins to maintain uniform air temperature
- Installed on crop dryer gas manifolds between the pressure regulating valve and the burner orifice (vapor or liquid withdrawal systems using a vaporizer)
