Swing Disc – In Line

UCC Inline Swing Disc Valves were designed for uni-directional on/off service in pneumatic conveying applications of dry ash. The design is rugged, easy to maintain and clean operating. This valve has replaceable abrasion resistant discs and seats that protect the valve body. The valve’s entrance incorporates a taper to concentrate the flow away from the valve body. Both of these features extends the service life and reduces the operating costs. The access cover allows the valve to be adjusted and maintained without removing it from the conveying line. UCC Inline Swing Disc Valves can be shipped pre-piped and fully assembled with an air cylinder and a variety of limit switches and solenoid valves which reduces field assembly and installation costs.

Swing Disk – In Line

  • Two piece body – Rugged and high strength design
  • Access Cover – Allows adjustments and maintenance to be performed in place.
  • Spring loaded packing design – Maintains loading during operation and prevents leakage
  • Swing disc design – Spring loaded disc pivots out of the flow path which increase component wear life
  • Heated seat option – Prevents build-up of sticky ash which improves performance and reduces maintenance
  • Valves are shipped pre-piped and fully assembled – reduced installation costs
  • Valves are rebuildable – extended service life of the valve
  • Limit Switches – Roller lever type and proximity are available with mounting brackets
  • Solenoids – Normally closed or open, voltage, manual operators, temperature rating and manufacturer
  • Pre-piping – Brass fittings with rubber hose, Swagelok stainless steel fittings and Swagelok stainless steel hoses, Swagelok stainless steel fittings and Swagelok rubber hoses

  1. Can maintenance be performed on the valve while it’s installed in the line[+]
    Yes, the two piece body and access cover allow the valve to be easily adjusted and maintained.
  2. When the valve is open, is the disc out of the flow of the ash? [+]

    Yes, the design of the body includes a “bluge” which allows the disc and lever to swing completely out of the material flow.

  3. What is the minimum air pressure required to actuate the air cylinder on these valves? [+]

    The operating range for the air cylinder is 60-125 PSI.

  4. What accessories can be ordered on these valves? [+]

    These valves can be ordered with an air cylinder and a variety of limit switches and solenoid valves. These valves can also be shipped assembled and pre-piped with the accessories.

NUVA FEEDER Dilute Phase Pressure System

The NUVA FEEDER® pressure system is optimal where conveying capacity requirements exceed the limits of a vacuum system. 

MultiDAC Dense Phase Pressure System

The MultiDAC™ system is intended primarily for short conveying distances.  Learn more about our MultiDAC Pressure System.


Vacuum Systems

The NUVEYOR® Vacuum System is an industry standard for efficient, reliable ash removal and is capable of conveying up to 80 TPH and distances of 1500 ft (450m).

Vacuum-Pressure Transfer System

UCC's Vacuum/Pressure Transfer systems combine the simplicity and lower headroom requirements of a vacuum system under the hoppers with the high capacity and long distance conveying capability of a positive pressure system.

Lime Handling

Lime Handling systems for wet scrubbers, dry scrubbers and fluidized bed boiler (FBB) applications.
