Drip Pan Elbow The Drip Pan Elbow, when used in con- junction with a safety relief valve, pro- vides a suitable unrestricted, self-drain- ing outlet. This improves the performance and longevity of the safety valve by alle- viating axial loads on the valve, which could impair its operation and shut off. In the interests of development and improvement of the product, we reserve the right to change the specification. Model ➪ DPE Sizes 3/4" to 4" 6" & 8" Connections Female NPT Flanged ANSI 125 Construction Cast Iron (ASTM A126 CL B) Local regulation may restrict the use of this product below the conditions quoted. Limiting conditions refer to standard connections only. Typical Applications Specifically for use on the outlet connection of safety/relief valves to assure unrestricted discharge. TI-3-2142-US 08.07 Sample Specification Drip Pan Elbows for use with safety/relief valves shall be ASTM A126 CL B Cast Iron, and be of the same size as the valve outlet or larger. Pipe as shown on the drawings. Installation The Drip Pan Elbow is to be connected to the discharge connection of the safe- ty/relief valve by a short pipe nipple. Flanged valves 4" and smaller will require a companion flange and short nipple the same size as the valve outlet. The drain connection on the bottom of the elbow should be piped to waste. Please refer to ASME code for additional installation details. Dimensions (nominal) in inches and millimeters SIZE A B C D E F G.
