Fisher CV500 Eccentric Plug Valve
Product Introduction
The Fisher CV500 Eccentric Plug Valve is a high-performance eccentric rotary control valve suitable for flow regulation and shut-off control under medium and high pressure conditions, and is suitable for industrial systems such as petrochemical, power, and water treatment.
Detailed parameters
|
Available Configurations |
Flanged valve body assembly with reversible(1) metal seat ring and splined shaft |
|
Valve Body Sizes |
NPS 3, 4, 6, 8, 10, 12; also available in DN 80, 100, 150, 200, 250, 300 |
|
End Connection Style |
Raised-face or ring-type joint flanges (per ASME B16.5); valve bodies with EN PN10 to PN100 flanges are also offered |
|
Maximum Inlet Pressure(2) |
Consistent with applicable ASME or EN flange ratings |
|
Shutoff Classification |
Class IV per ANSI/FCI 70-2 and IEC 60534-4 (0.01% of valve capacity at full travel), valid for both flow directions |
|
Flow Characteristic |
Modified equal percentage |
|
Flow Direction |
Forward (normal) flow is into the convex side of the V-notched ball; bidirectional flow is allowed from either side |
|
Flow Coefficient Ratio(3) |
200:1 (ratio of maximum to minimum usable flow coefficient, also referred to as rangeability) |
|
Actuator Mounting |
Right-hand or left-hand (viewed from the valve's upstream side). Mounting position depends on the required open valve position and flow direction for operational conditions; see the Installation section for details. |
|
Valve V-Notch Ball Rotation |
90-degree counterclockwise rotation to close (when viewed from the actuator side of the valve body) |
|
Valve Body/Actuator Action |
With a diaphragm or piston rotary actuator, field-reversible between push-down-to-close (extending actuator rod closes the valve) and push-down-to-open (extending actuator rod opens the valve) |
|
Options |
Sealed bearing constructions, purged bearings |
Core Advantages
Eccentric Structure: The eccentric rotation design reduces friction between the valve core and seat, minimizing wear.
Reliable Sealing: Meets Class IV sealing standards, with leakage ≤ 0.01% of rated flow.
Precise Adjustment: A high adjustability ratio of 200:1, combined with improved equal percentage flow characteristics, enables precise adjustment over a wide range, reducing fluctuations.
Bidirectional Flow: Supports bidirectional flow, adapting to different piping designs and reducing on-site installation limitations.
Applications
Petrochemical industry: Used for regulating high-temperature and high-pressure media, reducing the risk of leakage.
Electric power steam systems: Stabilizes steam flow and improves operating efficiency.
Water treatment systems: Suitable for circulating water and wastewater applications, ensuring stable flow.
Metallurgy and mining: Applicable to highly abrasive media, reducing replacement frequency.
Quality Control
Reliable Materials: Utilizes materials conforming to ASTM/EN standards; material reports are available.
Precise Manufacturing: CNC precision machining ensures accurate sealing.
Rigorous Testing: Comprehensive testing covering airtightness, pressure resistance, flow rate, and lifespan.
100% Factory Inspection: Complete machine inspection; factory test reports are available upon delivery.
