This manual shall be kept with care for future references. The symbols used in this manual have the following meanings.

  • Page 2: Specifications

    1. Specifications Model PF-7000 25A (Condensate inlet: 25A / Condensate outlet: 25A) 40A (Condensate inlet: 40A / Condensate outlet: 40A) Nominal size 50A (Condensate inlet: 50A / Condensate outlet: 50A) 80A (Condensate inlet: 80A / Condensate outlet: 50A) Application Steam condensate / Non-hazardous fluid...

  • Page 3: Dimensions And Weights

    2. Dimensions and Weights * Bush is attached at condensate inlet for the product of size 50A, and at condensate inlet and outlet for size 40A or less. * The unit is mm. Weight Size (kg) Rc1-1/2 Rc1-1/2 Driving Vent port fluid port Rc1/2 Fig.

  • Page 4: Operation

    4. Operation <State 1> Condensate flows into body [1] via the condensate inlet and then float [9] moves upward due to buoyancy. (See Fig. 3.) In this state, vent valve part of vent valve P is open and inlet valve part of inlet valve P is closed.

  • Page 5: Flow Rate

    5. Flow rate <Driving fluid: steam> Driving pressure <Driving fluid: air> Driving pressure * Flow rate described above indicates condensate volume when condensate flow-in height is 1,000 mm above the bottom of the product. (See 6.1 Piping example) Discharge capacity varies depending on condensate flow-in height. Multiply the volume by the following factors according to condensate flow-in height.

  • Page 8: Warning And Caution For Installation

    6.2 Warning and caution for installation Warning 1. Condensate may blow out from vent port following driving pressure drop or stop or failure of the product. Connect a pipe to the port and extend the pipe to safe place. * Failure to follow this notice may scald your skin by blowout of condensate. Caution Before installing the product, remove foreign substances and scale from the piping, and note that seal materials must not flow into the inside of the product or piping.
  • Page 9 11. Be sure to secure maintenance space needed for disassembly and repair of the product. (See Fig 7) The unit is mm. Fig. 7: Maintenance space 12. Recommended height of the condensate inlet is 300 mm or more. (See 6.1. Piping example.) 13.

  • Page 10: Operation Procedure

    7. Operation procedure 7.1 Warning and caution for operation Warning 1. Do not touch the product by bare hands when steam is flowing. * Failure to follow this notice may cause burn or injury. 2. Confirm that pipe joints are connected firmly and not unstable before letting the steam flow. * Failure to follow this notice may cause blowout of steam or condensate, resulting in scalds.

  • Page 11: Maintenance

    8. Maintenance Most of product failure is due to foreign substance inside piping. Be careful for foreign substance inside piping fully. Note that the customer will be required to pay repair charge for any defect that occurs due to foreign matter. Please understand. 8.1 Warning and caution for maintenance and inspection Warning 1.
