Armstrong B1670-5 Pressure Control Assembly (PCA) is the bucket mechanism and seat used in Armstrong steam-trap installations, designed for models 212, 812, 862, and 882. It features a 1/8-inch orifice and a 200 psi service rating, enabling precise pressure control within standard trap circuits. As an OEM PCA replacement, it integrates with Armstrong trap stations to restore original shutoff performance and reliable operation of the steam-trap system.
