Features
- Installation in straight, vertical or horizontal pipe.
- Minimal headroom is required for mounting
- Standard connections to ASME B16.5
- Rapid evaporation of water is achieved to minimize the accumulation of water in the line.
- Control within 10°F (6°C) of saturation is possible.
- Water turndown capacity of 50:1 (typically) or higher is available.
- Forged body with, stainless steel internals eliminates corrosion and vibration issues.
- Inconel 718 nozzles minimize wear.
- Replaceable Stellite® or 17% Cr seat for long life tight shut-off.
- Long trim life. Pressure drop is taken across the nozzles rather than the seating surfaces.
- Injection probe unscrews from body for easy capacity changes without changing stem/disc or seat.
- Actual performance depends on the application and in many instances may exceed the design characteristics above.
