1. Dimensions, weights, and flow coefficients are for reference only. When required, request certified drawings. 2. Face to face values have a tolerance of ±0.06 in (±2.0 mm) for sizes 10" and lower and a tolerance of ±0.12 in (±3.0 mm) for 12” sizes. 3. Cracking pressure is for horizontal installations only. For vertical installations, please consult factory.
