Fisher 667 HPS Globe Valve SS 316 with Emerson DVC6200

Fisher 667 HPS Globe Valve SS 316 with Emerson DVC6200 Positioner

The Fisher 667 HPS Globe Valve SS 316 with Emerson FIELDVUE DVC6200 Valve Positioner is the ultimate high pressure fluid control. The severe-service control valve assembly is developed specifically for severe differential pressures, corrosive media and demanding marine and industrial situations. This device features a heavy-duty, reverse-acting pneumatic diaphragm actuator and best-in-class digital diagnostics for superior throttling accuracy, long-term structural integrity and fail-safe reliability.

The Fisher HPS series single-port, high-pressure globe valve with durable cage guiding and unbalanced valve plug design. This assembly is constructed of high quality Stainless Steel 316 (SS 316) providing great resistance to pitting, crevice corrosion and harsh chemical attack.

Model Details:

• Valve Body Model: Fisher HPS
• Actuator Model: Fisher Type 667
• Positioner Model: Emerson FIELDVUE DVC6200
• Estimated MPN Configurations: HPS-667-DVC6200-SS.

Technical Specifications: Fisher 667

Key Features:

1. Superior Corrosion Resistance: All SS 316 body and trim metallurgy protects internal components from hostile maritime brines, offshore conditions and sour gas applications.
2. High Pressure Drop Capability The heavy-duty unbalanced plug and cage-guided design permits the valve to operate with a consistent throttling performance under severe pressure dips without extreme vibration.
3. Non-Contacting Stem Position Sensor The DVC6200 includes a non-contacting stem position sensor that minimizes the number of failure points associated with mechanical vibration and corrosive atmospheres.
4. Fail Safe Reliability: On loss of supply air, the Fisher 667 pneumatic actuator will positively place the system in a closed position.
5. Advanced Predictive Diagnostics The digital positioner features HART connectivity and provides valve health reports, friction levels and air usage without disturbing the online process.

Maintenance Guide by NDMarineTech:

• Instrument Air Quality: The Emerson DVC6200 is highly sensitive to moisture and particulate matter. Ensure your supply air passes through a fine-coalescing filter-regulator (like a Fisher 67CFR). Wet or oily air will clog the internal I/P converter.
• Packing Adjustment: If experiencing minor packing weeping under high pressure, tighten the ENVIRO-SEAL™ packing nuts in small, incremental quarter-turns. Avoid over-torquing, which increases stem friction and causes sluggish valve response.
• Bench Set Calibration: Always verify the actuator’s bench set limits on the nameplate before configuring your digital calibration sequence via a HART communicator.
