Okay, this is a comprehensive set of data across your requirements and multiple vendors. I will compile a report comparing each vendor’s offering against your detailed “Table 1” specifications for each valve.

I’ve extracted the most relevant information for comparison from your Table 1 data and cross-referenced it with the details provided for Masoneilan, Samson (from previous turns), and the new Flowserve (CTi Controltech) quote.

Comprehensive Control Valve Vendor Comparison Report

Purpose: To evaluate and compare the technical offers from Masoneilan, Samson, and Flowserve (CTi Controltech) against the specified requirements for each control valve listed in “Table 1”.

Key Considerations for Decision:

1. Technical Adherence to Specifications: How well does each vendor meet the specified valve type, size, material, fail position, trim, leakage, and performance (Cv, noise, travel) requirements?
2. Completeness of Scope: Do all vendors quote for all required valves?
3. Pricing: What is the total cost for the compliant packages?
4. Lead Time: What are the quoted delivery times?
5. Technical Justification for Deviations: Are any deviations from specifications clearly justified (e.g., larger size for noise reduction)?

Missing Valves (from Table 1)

All three vendors (Masoneilan, Samson, Flowserve) did not include quotes for the following valves from your “Table 1”:

• 131-PCV-0583 (Compressor BackPressure Valve)
• 131-PCV-0585C (N2 Valve)
• 131-PV-0581 (Dryer Regen BackPressure)

This is a critical gap in all quotes and must be addressed as a priority with all vendors.

Cost Summary (for the 11 quoted valves)

• Masoneilan Total: $118,634.00
• Samson Total: (Price not provided in previous turns, but identified as a “sizing report.” You would need to check the full quote for pricing.)
• Flowserve (CTi Controltech) Total (Globe Valves): $117,144.00
• Flowserve (CTi Controltech) Total (with Rotary Alternatives): $77,910.00 (This is a significant cost reduction if the rotary valves are acceptable for the application.)

Actionable Recommendations for Picking a Vendor

1. Address Missing Valves IMMEDIATELY: Contact all three vendors and request quotes for 131-PCV-0583, 131-PCV-0585C, and 131-PV-0581. This is non-negotiable for a complete project.

2. Review Valve Size Deviations:

   • Samson: Has the most frequent and significant deviations in quoted valve size compared to specified pipe size (e.g., 6" valve for a 2" line). While they justify it for noise, this requires detailed engineering review from your side. A larger valve means larger installation footprint and potential additional piping rework (reducers) if the line size is truly smaller.
   • Masoneilan & Flowserve: Also have some size deviations (e.g., 4" valve for 2" line, or 3" valve for 6" line). These are common for control valve sizing to optimize control or noise, selecting the best valve size for the required Cv.
   • Recommendation: For each instance of deviation (especially for 131-PV-0586, 131-FV-0065, 131-LV-0376, 131-TV-0385, 131-PV-0591, 131-TV-0361), ask the vendor for a clear technical justification for why they chose that specific valve size given the specified line size. Confirm if reducers are included if necessary.

3. Clarify Specific Material & Fail Position Mismatches:

   • Body Material: For 131-LV-0369 and 131-LV-0372, your spec is CS but Masoneilan and Flowserve quote SS or LTCS. Samson is consistent with CS or LTCS but deviates for 131-LV-0372. Clarify if the quoted material is acceptable or if you require CS for those specific valves.
   • Fail Position: For 131-FV-0065, your spec is FO but Masoneilan and Flowserve quote FC. This needs clarification and correction. Fail position is critical for safety.
   • Trim Materials (“Metallic” vs. “SS”): Ask Samson to specify the exact trim material grades (e.g., 316 SS, 17-4PH) to ensure they meet your SS trim requirement.

4. Evaluate Noise Performance:

   • For 131-PV-0586, Flowserve’s quoted noise (91 dBA) exceeds your normal target of 85 dBA, though it’s within the 115 dBA intermittent allowance. If continuous operation at 91 dBA is an issue, Masoneilan (81 dBA) and Samson (81 dBA) might be better.

5. Consider Flowserve’s Rotary Alternatives:

   • Flowserve offers significantly cheaper rotary valves (MaxFlo4) for several tag numbers. Rotary valves (like eccentric plug or ball valves) can be excellent for many control applications, offering cost savings and sometimes better capacity. However, they may have different control characteristics (e.g., rangeability, shutoff) compared to globe valves.
   • Recommendation: Review if the specific services (131-TV-0348, 131-FV-0065, 131-TV-0371, 131-LV-0372, 131-TV-0361) are suitable for rotary valves, considering their control requirements and fluid properties. If they are, Flowserve’s pricing becomes very competitive.

6. Lead Time: All quoted lead times seem similar. Ensure the lead time for the missing valves doesn’t significantly impact project schedule.

Preliminary Conclusion (Pending Clarifications & Missing Valves):

Based on the provided data for the 11 valves quoted:

• Flowserve (CTi Controltech) appears to offer the strongest overall package in terms of detailed technical breakdown, option for cost-saving rotary valves, and good adherence to specifications (with noted exceptions for size, body material, and fail position to clarify). Their detailed spec sheets are very helpful for verification.
• Masoneilan is also a strong contender with good technical compliance, though some size deviations and body material deviations exist.
• Samson has notable discrepancies in quoted valve sizes compared to specified line sizes, which requires careful engineering review and justification. The generic “Metallic” trim also needs specific clarification.

Next Steps:

1. Send a formal RFI (Request for Information) to all three vendors, specifically asking for:
   • Quotes for the three missing valves (131-PCV-0583, 131-PCV-0585C, 131-PV-0581).
   • Technical justification for all identified deviations in valve size vs. line size.
   • Clarification on specific trim materials (especially from Samson).
   • Clarification/Correction for body material and fail position mismatches.
   • Samson’s total price for the 11 valves + lead time.
2. Once you receive their responses, update this comparison table and re-evaluate. The decision will likely come down to technical compliance, justified deviations, and final pricing.
