E-MAIL: Adele C. Szuhai, Adele.C.Szuhai@lerc.nasa.gov. Valve Assembly shall include valve, actuator, positioner & position transmitter fully assembled per specifications as follows: A. SCOPE -- The pneumatic globe valve with a position feedback transmitter described here-in will be used to throttle an air flow. Valve inlet pressures will be as high as 1250 psig at 550 degrees F. B. VALVE 1. The valve will be used for air service in the temperature range of ambient to 550 degrees F. The environment temperature will be ambient. 2. The maximum shut-off differential pressure shall be 1250 psid at the above temperature range. 3. When installed in parallel with an existing 4 inch control valve with a Cv of 145, shall pass with a combined total air flow of 47.7 pps and steam flow of 20 pps at a minimum inlet pressure of 410 psig, temperature of 550 degrees F, and outlet pressure of 200 psig. (Shall have a flow coefficient of at least 500 at full open). 4. Shall have linear trim. 5. Valve shall have a minimum rangeability of 50 to 1. 6. The valve seats shall have an ANSI B16.104 class 3 shut-off as a minimum. 7. The valve bodies and flanges shall have an ANSI class 900 rating. 8. The valve shall mate with an 8 inch 900 lb ANSI flanges. 9. The valve body and seat shall be 316 stainless steel. The valve plug and stem shall be 17-4 PH stainless steel. 10. Valve shall have a 316 stainless steel high capacity noise abatement trim to limit the noise level to 102 dba maximum 3 feet downstream and 3 feet away from the valve when the valve is operating at the condition defined in specification B.3 Maximum noise level shall be for an uninsulated valve. 11. The valve shall have a permanent tag showing. a. Maximum working pressure b. Maximum operating temperature. c. Maximum Cv and type of trim d. Full valve model number and serial number C. Pneumatic Actuator 1. The actuator when supplied with 100 psig air shall stroke the valve full stroke with a 1250 psi differential pressure across the valve seat. 2. The actuator shall provide full valve travel. 3. The actuator shall have a positioner. A 3-15 psig signal to the position shall stroke the valve from full closed to full open. D. Position Feedback Assembly 1. Position feedback shall be provided by a position transmitter with a 4-20 ma output. 2. The position transmitter shall be enclosed and easily removable for servicing. E. Documentation 1. Documentation shall include a mechanical drawing with overall dimensions for the valve assembly, and manuals for the position transmitter and valve. Included in the manuals, as a minimum, shall be descriptive information showing an assembled picture of each component and how it operates, and electrical schematics showing how the position transmitter is wired to the electrical receptacles.
