Plate Valve Technical Specifications

At Triangle Pump Components, we offer a premium plate pump valve for rigorous applications and
environments. Capable of pumping ammonia, gasoline, petrochemicals, hydraulic fluid, sulfuric acid, and many other abrasive and corrosive materials, this double-sprung valve operates under pressures up to 15000 psi.

Our plate valves, available in a broad range of sizes, are made of:

  • 316 Stainless Steel
  • Monel®

In addition to this base material, customers may select a Delrin®, Stainless Steel, Sustakon® or a titanium disc for their valve.

We proudly manufacture and test all of our plate valves up to the highest industry and specialty standards,including:

  • ASTM
  • ISO 2001:9008
  • Mil-Spec
  • NACE

Triangle Pump takes on high and low volume orders, prototyping, and specialty production. In addition to our manufacturing capabilities, we offer CAD design and CAM programming services to reverse engineer parts for our customers. We accept TurboCAD (TCW, TCX) and Unigraphics (PRT) file formats for these services.Plate-Valve-Technical-Specifications

Plate Valve Installation

All Triangle Pump valves are designed to be long-lasting, but proper valve installation is crucial for maximizing operating efficiency and extending the service life of your system.
To ensure the safe, proper installation of your plate valve, follow along with these steps:

  1. Before beginning any installation work, familiarize yourself with all federal and state safety and environmental regulations.
  2. As a safety precaution, make sure that the pump’s power source is completely off, locked out, and tagged before starting.
  3. Prior to installation, pump ports must be clean and free of any foreign matter, rust, or corrosion. Clean and dry the tapered part of the valve seat, as well.
  4. Place the valve seat in the pump port and press down with the palm of your hand, making sure the seat is aligned straight and level in the port.
  5. Place a short wood block — of sufficient size to cover the entire seating diameter — on top of the seat.
  6. Tap the valve 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 and pump action will seat the unit precisely and firmly by equalizing liquid pressure.
  7. Apply three to four dabs of anti-seize compound to the threads in the valve cage and align the following pieces from top to bottom: valve cage, spring, valve member, insert (either an o-ring or a gasket), lock-ring, and seat.
  8. Push the cage down with the valve stem aligned in the hole and begin engaging the threads on the seat until they make contact with the lock-ring. At this point, you can use a Crescent wrench or similar tool to continue screwing the cage down until it becomes metal-to-metal with the seat.
  9. Once secured, the valve (wing) should be able to move freely up and down in the valve seat. Turn the pump over by hand to make sure the plunger and packing are in proper alignment.
  10. Note: Be cautious about over-tightening the fastener, as this could freeze the valve shut and possibly expand the retainer stem. Position the retainer stem on top of the valve plate while tightening the fastener.
  11. Once you’ve completed these installation steps, your plate valve is ready for use. Keep in mind, however, the importance of performing routine maintenance checks on your system. Repairing or replacing worn-out components including the valve disc, spring, sleeve, locknut, or bolt will optimize pump performance and extend its overall lifespan.
