Offerors shall provide the requested date and time and the attendee's name and company. Attendees must be U.S. citizens and present a valid identification card (driver's license or state-issued ID). Required PPE is steel-toed boots and a hard hat. Photography, measurements, and tooling are permitted.

2. Question: May Sentiq designate a qualified New Orleans valve supplier or application engineer as its authorized representative for the physical visit, while Sentiq remains the offeror and prime contractor? Please confirm whether a Sentiq corporate officer or employee must also attend.

Government Response: Yes. An offeror may designate an authorized representative to attend the site visit on its behalf.

3. Question: Please provide the existing valve and control system manufacturer, model, serial number, nameplate data, photographs, arrangement drawing, piping and instrumentation diagram, flange dimensions, maintenance history, and available installation envelope, if these records exist.

Government Response: The existing valve is a Leslie 3-way rotary valve, RVMB model (with manual), 8-inch, 150 PSIG, with an 1,800 GPM capacity. Required outlet pressure at no flow is 34 PSIG.

The port-side valve fail position is Port A closed. The starboard-side valve fail position is Port B closed. See attached drawings/documents: 48-24-02 Sheet 3 of 6; 48-04-241 (Fresh Wtr Cooling - Fwd Fr 61 L-M) Sheet 7; 48-04-24 (Fresh Water Cooling - Fwd Fr 61) Sheet 2; and 3-Way Valve Figure.

4. Question: Is the valve used for mixing or diverting? Please identify the inlet and outlet ports, normal flow path, rising temperature action, required fail position, action on loss of signal or air, mounting orientation, and manual override clearance.

Government Response: The valves are used for mixing. See the attached 3-Way Valve Figure for identification of the inlet and outlet ports. The port-side valve fail position is Port A closed.

The starboard-side valve fail position is Port B closed.

5. Question: Please provide normal and maximum flow, required flow coefficient, inlet and outlet pressure, allowable pressure drop, maximum differential pressure, design pressure, normal and extreme temperature, control setpoint, acceptable control tolerance, and required response.

The existing valve is rated at 1,800 GPM capacity, and the required outlet pressure at no flow is 34 PSIG.

6. Question: The medium is written as Fresh Water and MarineCare Caretreat. Please identify the exact fluid, treatment product, concentration, temperature, and material and seal compatibility requirement.

Government Response: The treatment product is Marine Care Americas Caretreat 2 Diesel (NCLT), diesel engine water treatment. Each side holds approximately 5,000 gallons of water/coolant. The mixture ratio is 1.6 gallons of coolant to every 100 gallons of water, or approximately 91 gallons of coolant per side.

7. Question: Please define 150 RF, STD, including the governing flange standard, class, drilling, facing, material, bolt pattern, and required flange-to-flange length.

Government Response: See attached drawings/documents: 48-24-02 Sheet 3 of 6; 48-04-241 (Fresh Wtr Cooling - Fwd Fr 61 L-M) Sheet 7; 48-04-24 (Fresh Water Cooling - Fwd Fr 61) Sheet 2;

8. Question: Please identify the required pneumatic controller, sensor, thermowell, signal direction, proportional and integral behavior, sensor range, insertion length, process connection, mounting, enclosure, air supply pressure, air quality, filtration, and regulation.

Government Response: The current configuration uses a Fisher 4196 controller, proportional + reset control mode, 50-159 degree temperature range, 10.5-inch insertion length, and 6-30 PSIG output signal. Offerors may propose a controller that works with the proposed valve/valve pneumatic actuator; the controller does not have to be the Fisher 4196 specifically.

9. Question: What hydrostatic pressure and seat leakage standards, pressures, durations, and acceptance limits apply? Must testing be witnessed or certified by a named independent or marine classification body?

Government Response: Valves are to be tested to U.S. Coast Guard (USCG) and American Bureau of Shipping (ABS) Class II piping requirements.

10. Question: Please confirm that the award covers supply and destination delivery only, with shipboard removal and installation excluded.

Government Response: The solicitation is for procurement and destination delivery of the specified valves and pneumatic control system. Shipboard removal and installation are not included in the requirement.

11. Question: Federal Acquisition Regulation provision 52.212-2 retains placeholder language before listing Technical Acceptability and Price. Please confirm the evaluation order, relative importance, and the exact technical submission elements required for acceptability.

Government Response: Award will be made based on price. Offerors shall submit the technical information required by the solicitation, including General Arrangement (GA) drawings, Piping and Instrumentation Diagrams (P&IDs), and product data, to demonstrate compliance with the solicitation requirements. Technical submissions will be reviewed for compliance with the solicitation requirements and are not separately rated evaluation factors.

12. Question: Please confirm the quotation email recipient or recipients, required subject line, file formats, size limit, pricing format, signed forms, representations, certifications, and acknowledgment requirements.

Government Response: Quotations shall be submitted electronically in accordance with the solicitation instructions. The email subject line shall state "W912P8-26-Q-A039 - Pneumatic 3-Way Temperature Control Valves." Pricing shall be provided in accordance with the solicitation's CLIN structure. Offerors shall submit all required information and documentation identified in the solicitation, including any applicable representations and certifications, and shall acknowledge receipt of all amendments issued prior to the quotation due date. No additional file format or file-size requirements apply beyond those stated in the solicitation.
