Scope of Work

Propulsion Systems Laboratory (PSL) 450 Heated Air High Temperature & Pressure Control Valves

Procurement

Background

The PSL, in order to satisfy future customers’ requirements is in the process of installing an extension of the 450 psi, heated air line to Cell 3. Three high temperature, high pressure valves are required to control hot air delivery to the customer test model as well as system operation. The valves to be procured will match those in the existing portion of the Heated 450 Air system.

Specification

The valve specification is as follows:

Media: Hot air / Design pressure: 450 psig, Design Temperature: 1200°F

1. Leusch (Samson) Model LTR43-2 Triple-offset Butterfly Valve, 8” size, A351 CF8M SST body, ANSI Class 900#, RF Double Flange, 500mm extension for higher temperatures. A351CF8M disc, SS321H/stellited seat & shaft, Class V shutoff FTC, inherent characteristic, Cv: 1146 c/w Type BR31A (SRP 4000-A) pneumatic actuator, Fail-closed c/w Type 3730-2 Digital Positioner, 4-20 milliAmp input, Intrinsically-safe must include position transmitter (4-20 milliAmp output) c/w Type 4747 Limit Switch Assembly c/w Type 3755-1 Pneumatic volume booster c/w Type 4708-45 Air filter/regulator

2. Same as Item 1, except:

Leusch (Samson) Model LTR43-2 Triple-offset Butterfly Valve, 6” size Cv: 644 c/w SRP 3000-A actuator
