Guarding Your Home to Armored Door Military Specifications

Question Size (DN) Misalignment 2025-06-26 12:02:59.054 +

Issue: Incorrect valve size causing excessive pressure drop or insufficient flow. Solution: Calculate Cv/Kv values and pipe diameter requirements.

Question Inadequate Seal Selection 2025-06-26 12:02:51.472 +

Issue: Leakage due to improper sealing (e.g., EPDM seals degrading in oil applications). Solution: Choose seals (elastomer, metal, PTFE) compatible with the fluid and temperature.

Question Poor Flow Characteristic Understanding 2025-06-26 12:02:44.336 +

Issue: Linear vs. equal percentage flow characteristics misunderstood, causing control instability. Solution: Select trim/design based on required flow control precision (e.g., V-port ball valves for modulation).

Question Pressure and Temperature Oversights 2025-06-26 12:02:36.263 +

Issue: Ignoring pressure/temperature ratings, leading to valve failure (e.g., thermal expansion or seal degradation). Solution: Ensure valves meet PN/Class ratings and account for extreme conditions (e.g., cryogenic or high-temperature applications).

Question Mismatched Valve Type for the Application 2025-06-26 12:02:28.263 +

Issue: Selecting a valve type unsuitable for the process (e.g., using a butterfly valve for high-pressure throttling). Examples: Ball valves for on/off service vs. globe valves for precise flow control. Check valves for preventing backflow in pump systems. Solution: Match valve type (ball, gate, globe, diaphragm, etc.) to the function (isolation, regulation, backflow prevention).

Question Incorrect Material Compatibility 2025-06-26 12:02:18.570 +

Issue: Choosing materials incompatible with the fluid (e.g., corrosion, erosion, or chemical reactions). Example: Using carbon steel valves for highly corrosive acids. Solution: Verify material compatibility (e.g., stainless steel, Hastelloy, PTFE-lined) with the fluid properties (pH, temperature, concentration).
