PlenaFlow® Plate Valve Installation

Proper plate valve installation is crucial for maximizing operating efficiency and extending the service life of your system. Like all Triangle Pump Component valves, the PlenaFlow® plate valve is designed to be long-lasting when accurately installed.

PlenaFlow® Plate Valve Components

To ensure the safe, proper installation of your PlenaFlow® plate valve, follow these steps:

  1. Pump ports must be clean and free from foreign matter, rust, or corrosion.
  2. Clean and dry the tapered part of the valve seat.
  3. Place the valve seat in the pump port and press down with the palm of the hand making sure the seat is aligned straight and level in the port.
  4. Place a short wood block on top of the seat. The wood block should be of sufficient size to cover the entire seating diameter.
  5. Tap lightly with a hammer or mallet. Under no circumstances should you use a sledge or heavy blow of any kind directly on the valve seat. A properly fitting valve seat will be “home” with light tapping. Pump action will seat the unit precisely and firmly by equalized liquid pressure.
  6. Install valve, springs, retainer, and fastener. For assembly order see Typical Plate Valve Assembly exploded diagram above. 
  7. Rotate the pump crankshaft by hand to make sure plunger and packing are in proper alignment.

Caution: It is possible to freeze a valve closed by:

  • Over tightening the fastener. This can possibly expand the retainer stem.
  • Positioning the retainer stem on top of the valve plate while tightening the fastener.
