Johnson Controls V47AD-2 Valve Els PW 29614 This specific length is criticalThe Johnson Controls V47AD 2 Valve is a rugged, 1 inch NPT direct acting temperature actuated water regulating valve engineered specifically for high demand heating applications. This cast iron regulator utilizes a specialized Style 4 sensing bulb (11 16" diameter x 6" length) and a 6 foot capillary to modulate water flow based on sensed temperature deviations. Featuring a heating point range of 115F to 180F, the V47AD 2 is technically identical to
