The Iso-Dome accessory for the 400 pilot provides protection of the critical pilot internals from the process media.
The pilot is actuated by the process fluid and is ASME Section VIII Code stamped for gas and liquid service.
Features & Benefits:
- Critical Pilot Internals and Main Valve Dome Protected from Process Media – Expands the application of pilot operated valve technology.
- Valve is Fail-safe – Meets ASME code requirements.
- Allows System Operating Pressure to be Near Set Pressure – SRV tightness is maintained, resulting in greater system throughput.
- All Adjustments are Factory Sealed – Just add the clean gas supply for simple and inexpensive field installation.
- Modulating Action – Minimizes fugitive emissions, product release, product loss, and noise.
- Valve Operation Insensitive to Back Pressure – Costly and fragile metal bellows not required.
- Unique Field Test Capability – Set pressure may be verified while valve remains in service protecting the system. No system isolation valve or rupture disc required.
