Rotary Plug Valve Type 72.4

Product catalog summary

Overview: The document is a technical data sheet for the Rotary Plug Valve Type 72.4, designed for process engineering and industrial applications. It provides detailed specifications, operational principles, and ordering information.

Specifications:

Valve Size: DN 25 to DN 300 (NPS 1 to NPS 12)
Nominal Pressure: PN 10 to PN 40 (ANSI Class 150 and 300)
Temperature Range: -100 to 400 °C (-148 to 752 °F)
Materials: Cast/carbon steel or stainless cast/carbon steel
Seat Versions: Metal sealing (armored/unarmored) or soft sealing

Design and Features:

Double eccentric design for smooth operation and stable control response.
Available in sandwich-style body without flanges.
Compatible with various accessories like positioners and solenoid valves.

Operational Principles:

The valve features a double-eccentric design allowing smooth plug lift-off without initial breakaway torque.
Flow direction for gases and vapors is FTC (medium closes).
Flow characteristics can be modified to linear or equal-percentage using positioners or cam disks.

Fail-Safe Actions:

Valve can be configured to close or open without supply air using Type R/M/AT/S Rotary Actuators.

Technical Data:

Rangeability: 200:1
Opening Angle: 75°
Materials: Various materials listed for body, shaft, plug, and seals.

Flow Coefficients:

Detailed Kvs and Cv values provided for different seat types and flow directions.

Dimensions and Weight:

Face-to-face dimensions provided for both DIN and ANSI standards.
Weight varies from 6 kg to 168 kg depending on valve size.

Ordering Information:

Includes specifications for type, valve size, nominal pressure, body material, seat version, flow characteristics, actuator type, and fail-safe action.

Principle of operation The shaft/plug arrangement is eccentric (Figs. 3 and 4). The double-eccentric design of the rotary plug valve is achieved in combination with the offset of the plug's pivot. When turning the plug shaft from closed position in opening direction, the double-eccentric design allows the plug to lift off the seat smoothly without initial breakaway torque. The valve is not opened suddenly and shows a stable control response even with small opening angles. The rotary plug valve can be used for both directions of flow. Double-eccentric principle For gases and vapors, the direction...
