- Total Steam Control—Combines pressure and temperature control in a single valve.
- Full Pressure Drop Capability—Rugged cage-guided design enables handling of full pressure drop of main steam.
- Noise Attenuation—Whisper III and WhisperFlo trims help to attenuate the noise by 30 to 40 dBA, respectfully.
- High Temperature Capability with Standard Class V Shutoff—Use of the patented Fisher Bore Seal trim gives capability of Class V shutoff as a standard up to 593°C (1100°F). This unique balanced trim is field-proven.
- Forged Valve Body—FEA designed valve body can handle the most demanding applications without thermal stress problems.
- Flow Up Angle—Permits vertical stem orientation for ease of maintenance in most applications.
- Thermally Compensated Trim—The cage is case-hardened for maximum life and is allowed to grow during thermally induced excursions. The plug is continuously guided and employs cobalt-based overlays for guide bands and tight metal-to-metal shutoff against the seat.
- Easy Maintenance Seat Ring—No bolting or gaskets used in the flow stream. Welded design provides Class V shutoff and long life. Deep Alloy 6 overlay can be refinished multiple times to maintain tight shutoff.
- Spiral-Wound Gaskets for Excellent Bonnet Sealing Under All Service Conditions—Premium gaskets provided with N06600 windings and graphite filler material.
- Precise Spraywater Injection—CFD designed spray manifold determines water injection point and insertion depth to maximize mixing and quick vaporization.
- High Turndown—Standard trim control rangeability is 50:1. Special construction can provide up to 75:1 turndown.
- Quick Stroking Actuation—High performance pneumatic piston actuators with FIELDVUETM digital valve controllers can achieve full stroke in less than 2 seconds while still maintaining highly accurate step response. Optimized digital valve controllers are available when high stroke speeds are required. Contact your Emerson Process Management sales office for assistance.
- Performance Diagnostics—With the self-diagnostic capability, questions can be answered about a valve's performance, without pulling the valve from the line. The present valve/actuator signature (seat load, friction, etc.) can be compared against previously stored signatures to discover performance changes before they cause process control problems.
