Overview
The Johnson Controls V50AE-3C is a self-operated modulating valve designed to regulate gas flow on natural or LP gas-fired outdoor crop dryers to maintain a desired air drying temperature. Changes in air temperature at the sensing bulb cause the vapor pressure sensing element to oppose the range spring, modulating the gas supply to the main burner.
Features
- Free movement of parts provides fast, uniform response.
- Easy temperature adjustment by turning the T-handle range screw on top of the spring housing.
- High-temperature diaphragms suitable for most LP gas units.
Specifications
- Temperature Range: 140 to 250°F
- Capillary Length: 15 feet armored capillary
- Bulb Dimensions: 11/16 x 16-1/4 inches
- Maximum Working Pressure: 30 PSIG (207 kPa)
- Body Style: 2-way valve configuration
Applications
- Designed strictly for outdoor crop dryer service to control gas flow on manifolds.
- Suitable for vapor withdrawal systems or liquid withdrawal systems utilizing a direct or indirect vaporizer.
- Not intended for use as an expansion valve handling liquid LP on straight liquid withdrawal systems or any other application type.
