Features
- ENVIRO-SEAL™ packing systems that provide an improved stem seal to help prevent the loss of process fluid are available. These packing systems feature PTFE or Graphite ULF packing with live-loading for reduced packing maintenance.
- Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise.
- Streamlined flow passages in the ED, EAD, and EDR valves provide excellent capacities and flow.
- Increased wear resistance of hardened stainless steel trim means longer-lasting service.
- Use of multiple graphite piston rings permit Class IV shutoff up to 593°C (1100°F). Use of C-seal trim permits Class V shutoff up to 593°C (1100°F).
- Valves are available with dimensions specified by EN/DIN standards.
- Unless otherwise noted, references are to NACE MR0175-2002. Optional materials are available to meet NACE MR0103 and NACE MR0175 / ISO 15156.
