Product catalog summary
Overview: The document provides detailed specifications and features of Top-Flo® Automated Flow Control Valves, suitable for industries such as food, beverage, dairy, cosmetics, pharmaceuticals, biotechnology, and electronics processing. These valves are made from stainless steel and are designed for high-temperature and chemically resistant applications.
Key Sections:
  • DCx3 and DCx4 Valves: These sections describe single sealing shut-off and divert valves featuring a patented PFA floating plug seal, heavy-duty stainless steel pneumatic actuators, and various body configurations. Specifications include size ranges from 1” to 6”, materials used, connection types, and service conditions such as maximum temperature and pressure.
  • Fractional DCx3 and DCx4 Valves: Focuses on smaller size valves (1/2” to 1”) with similar features to the larger valves, emphasizing ease of cleaning and chemical resistance.
  • Diaphragm DCx3 and DCx4 Valves: Highlights the use of a PTFE diaphragm type stem/body seal for environmental isolation and includes an integral micro valve for diaphragm failure indication.
  • DCx3 DE – Double Sealing Shut-off: Describes a non-independent double valve system with an internal leakage chamber to prevent cross-contamination, suitable for sizes 2” to 4”.
  • DCx3 Regulating Valves: These valves feature a stainless steel parabolic stem profile for fluid control, with specifications for size ranges from 1” to 4” and service conditions including maximum working pressure and temperature.
  • DCx3 FdC – Tank Bottom Single Sealing Shut-off: Details the design for minimal fluid retention and options for rising or lowering plug types, suitable for tank bottom applications.
Performance and Testing: The valves meet ISO 5208 standards, with performance curves provided for pressure drop across various sizes and configurations.
Additional Features: Options for manual and automated operation, various seal materials, and network connectivity options are available to customize the valves for specific applications.
Seal Options: The document outlines optional seals including EPDM, FKM, or Silicone for plug, stem, and body seals. These materials are chosen based on their compatibility with different service conditions.
Tank and Connection Specifications: The tank connection is a special flange designed for welding. Connections include OD tube butt-weld and sanitary clamp with a 45° outlet, with other options available upon request.
Signal Equipment: The document specifies ICS and ACS control tops for different valve sizes, with network options including point-to-point and AS-i. Additional options are available upon request.
Surface Finish: The interior surface finish is specified as 32Ra, while the exterior is between 40-50Ra, ensuring smooth surfaces for sanitary applications.

Working Conditions: The working temperature range is from +23°F to 248°F, with a sterilization temperature of 266°F. The maximum working pressure is 130 psi, with specific conditions for cleaning operations.
Innovative Technology: The document highlights the use of PEEK intermediate plugs and sliding O-rings for enhanced sealing and maintenance ease. The ACS control top offers advanced control and command options.
Body Configurations: Various main body configurations are available, with additional configurations upon request.
Tank Bottom Mixproof Features: The VDCI-MC FdC series includes features like a patented PFA floating plug seal, minimal fluid retention design, and integral micro valve for secondary seal cleaning.
Specifications:
1. Actuator Air Supply: Minimum 80 psi, Maximum 116 psi.
2. Vacuum Resistance: 0.4 cm3/s.
3. Materials: Body and stem made of 316L stainless steel, operator made of 304 stainless steel. Valve seals include FKM and optional EPDM.
4. Surface Finish: Interior 32Ra, Exterior 40-50Ra.
5. Service Conditions: Max temperature 248°F, Min temperature -32°F.
Procedures and Features:
1. Manual Pressure Relief: Allows for manual adjustment of relief pressures with three spring ranges.
2. DCx3 Relief Valve: Predetermined relief pressure for overpressure protection, can be activated for clean-in-place operations.
3. Tank Service Vacuum-Pressure Relief: Automatic seat lift and retraction to prevent overpressure and vacuum conditions.
Norms and Recommendations:
1. Temperature Range: Recommended -5°C to +140°C.
2. Set Pressure: 0.2 to 12 bar with reduced tolerance due to fine thread.
3. Plug and Seals: Options include standard or balanced plug, PFA or elastomer seals.
Advantages:
1. High Precision: Easy adjustment with a standard wrench, high precision response during excess pressure.
2. Security: Meets standards for protection against excessive pressure.
3. Compact Design: Integrated adjustment system in the valve.
Additional Features:
1. ACS and ICS Control Units: Modular design with user-friendly interface, quick-fitting electric and pneumatic connections.
2. Customized Equipment: Pigging systems and manifold scraping systems tailored to specific processes.
Critical Information:
1. Pressure Tolerance: +/- 15% of set pressure.
2. Max Working Pressure: 116 – 174 psi depending on valve size.
3. Optional Features: Air assist with regulator for increased relief pressures.
