The Johnson Controls V47AD-1C is a temperature-actuated modulating valve, ideal for applications where precise temperature control is paramount. Weighing 10 lbs, it is designed to withstand water supply pressures of up to 150 psig, making it suitable for a range of plumbing and HVAC systems.

With a pipe connection of 1 inch NPT, the valve fits seamlessly into existing setups. It operates within a specified temperature range of 75°F to 135°F, ensuring effective modulation according to ambient conditions. The incorporated bulb measures 11/16 x 16-1/4 inches, playing a critical role in the valve's response to temperature changes.

A standard bypass orifice diameter of 0.093 inches is included to facilitate controlled flow, while the maximum bulb temperature can rise to 20°F (-6.7°C) beyond the specified working range. Additionally, the V47AD-1C can handle water temperatures up to 170°F (77°C) to accommodate various operational demands.

The valve's capillary is covered with nylon armor for added protection, ensuring durability in challenging environments. Mounting is vertical with the temperature sensing element oriented downwards for optimal functionality. The valve disc is crafted from Buna-N, providing superior sealing capabilities.

This combination of features makes the Johnson Controls V47AD-1C a reliable choice for those needing precise and durable temperature control in their systems.
