Okay, this is a comprehensive request! I will analyze the quotes from Baker Hughes Masoneilan, Samson, and Flowserve (as per the provided documents) against your detailed specification tables.
Important Note: The prompt provided an initial analysis for Baker Hughes Masoneilan. I will incorporate that while also performing a fresh, line-by-line comparison for Samson and Flowserve.
Overall Goal: To identify which vendor’s quote best aligns with your technical specifications, note any discrepancies, and provide recommendations for selection.
Executive Summary
After a detailed review of the three vendor quotes against your component specifications, it’s clear that none of the vendors currently provide a fully compliant quote across all items. Each vendor exhibits significant discrepancies that require further clarification or re-quoting.
Key Findings Overview:
- Samson:
- Major Red Flag: Actuator instrumental air supply pressure is consistently NON-COMPLIANT with your specifications (often quoted at 1.4-3.8 bar vs. your 4.0-4.5 bar(G) min/norm). This is a critical functional failure point.
- Frequent discrepancies in quoted valve size compared to pipe size (often smaller valve DN for larger pipe data).
- Several occurrences where calculated valve travel exceeds your specified limits.
- Missing three valves from the overall list.
- Generic trim material descriptions (“METALLIC”).
- Flowserve:
- Consistent pattern of quoting valves that are mechanically smaller than your specified pipe size. While this can sometimes be a valid sizing choice, the extent here suggests potential issues without clear justification.
- Several instances of material mismatches (e.g., Cast Stainless Steel or LTCS quoted when Carbon Steel was specified).
- Multiple occurrences of noise levels exceeding limits, particularly for flashing services.
- Discrepancies in valve type (e.g., quoting rotary for a globe valve) or fail position.
- Trim material descriptions need detailed verification against “hardened stellite” requirement.
- Baker Hughes Masoneilan: (Based on the analysis provided in the original prompt, which I’ve validated)
- Size discrepancies are a primary concern, similar to Flowserve.
- Actuator air supply mismatch (similar to Samson, though less widespread than Samson’s system-wide issue).
- Generic trim material descriptions, needing verification for hardened stellite.
Recommendation (Preliminary):
At this stage, do not select any quote directly. You must go back to each vendor with a detailed list of non-compliances and request a revised technical offer. The significant discrepancies, particularly around functional aspects (actuator air, sizing for performance, noise), suggest that these quotes, as they stand, are not fit for purpose without substantial revisions.
Detailed Comparison Report
This report will break down each valve’s specifications and compare the offerings from each vendor.
Terminology:
- Match: Vendor’s specification meets your requirement.
- Discrepancy: Vendor’s specification differs from your requirement.
- Clarification Needed: Information is ambiguous or requires more detail from the vendor.
- FATAL FLAW: A critical non-compliance that renders the component unsuitable unless corrected (e.g., incorrect actuator air, major material mismatch for critical service).

12. Missing Valves in Samson’s Quote:
The following valves, present in your specification tables, were not found in the provided Samson Sizing sheets:
- 131-PCV-0583 (Compressor BackPressure Valve)
- 131-PCV-0585C (N2 Valve)
- 131-PV-0581 (Dryer Regen BackPressure)
Action: You must request quotes for these missing valves from Samson.
Consolidated Action Plan
Given the extensive discrepancies, here’s how to proceed:
-
Prepare a Detailed Inquiry to Each Vendor:
- For each vendor (Baker Hughes, Samson, Flowserve), provide a consolidated list of the discrepancies identified above, citing specific valve tag numbers and the exact non-compliance.
- Specifically highlight the “FATAL FLAWS” (e.g., Samson’s actuator air pressure, Flowserve’s consistent noise issues for flashing services, major material mismatches).
- Demand a re-quote for all items where discrepancies exist, ensuring full compliance with your specifications.
- For trim materials, explicitly ask for confirmation that the quoted material meets the “hardened stellite” requirement for cavitating services. If not, request an upgrade and associated cost.
- Request missing quotes from Samson for the unquoted valves.
-
Evaluate Revised Quotes:
- Once revised quotes are received, repeat this detailed comparison process.
- Pay close attention to how new proposals address the previously identified issues, especially the FATAL FLAWS.
- Compare the revised pricing against each other, noting any significant cost increases due to compliance upgrades.
- Consider overall lead times and delivery schedules in your decision after technical compliance is assured.
Without clear, compliant, and verified technical tenders, selecting a vendor at this stage would carry significant project risk.
