The V47AD-2C model is a modulating valve from the V47 Series by Johnson Controls that responds to changes in temperature for regulated control in heating systems. Weighing 10 lbs, this valve is designed to withstand a maximum water supply pressure of 150 psig. Constructed from cast iron with a rust-resistant coating, it offers durability and resistance to environmental factors.
This valve supports a pipe size of 1 inch and features a Buna-N disc, enabling effective operation at high temperatures. The opening point range is designed for heating applications, operating effectively between 115 and 180 °F. The temperature bulb, measuring 11/16 x 6 inches, is critical for accurate temperature sensing.
Included with the valve is a standard bypass orifice with a diameter of 0.093 inches, facilitating controlled flow. The design permits the bulb to operate safely with a maximum temperature of 20 °F below the maximum limit of 170 °F (77 °C). A nylon armor capillary protects the sensing element from wear during operation. Vertical mounting is required for this valve, ensuring that the temperature element is pointed downward for optimal performance.
