General industry

Compressed air, steam, thermal oil

Limitations for 304 SS body:

  • Not suitable for strong oxidizing media (e.g. concentrated nitric or sulfuric acid – use 316/316L)
  • Avoid high chloride concentrations (risk of stress corrosion cracking)
  • For >200°C, use PPL seats or metal seated design

  1. Installation & Maintenance Notes
  1. Pre-installation check: Verify valve size, material, pressure rating match line requirements. Clean pipe interior to avoid damaging sealing surfaces.
  2. Flange connection: Use gasket conforming to ASME B16.5 (e.g. spiral wound or PTFE). Tighten bolts evenly in a cross pattern to avoid flange misalignment.
  3. Əməliyyat: Handle parallel to pipe = open; perpendicular = closed. Do not use extension levers or impact tools.
  4. Temperature effect: PTFE/RPTFE seats may expand at high temperature, increasing torque. Allow margin in actuator sizing.
  5. Maintenance: Inspect operation and sealing every 6 months. For valves idle for long periods, cycle the valve periodically to prevent seat adhesion.
