Among our diverse product offerings at Triangle Pump Components, Inc. is the Abrasion Resistant (AR) Valve, designed for applications enduring some of the heaviest wear. This valve, available in two different varieties, is ideally suited for use in pumping environments containing abrasives or small solids and high pressures.

New Call-to-action

While our standard AR valve seats come in 316 Stainless Steel, they are also available in 17-4 hardened Stainless Steel and other alloys. The valve member is made of the same material as the seat, either with or without a polyurethane insert for use in temperatures below 160°F. For higher temperature applications, we provide fluoroelastomer inserts.

Abrasion Resistant (AR) Valve Technical Specifications

Triangle Pump’s abrasion resistant (AR) valve is ideal for the most rigorous applications and pump systems. Able to pump abrasive media such as acid, hazardous chemicals, chlorine, and small solids under pressures up to 15,000 psi, this reciprocating pump AR valve is the most durable product available in today’s marketplace.

The Triangle Pump Abrasion Resistant (AR) Valve encompasses a wide array of sizes and is most commonly sold in:

  • 316 Stainless Steel
  • 17-4 Hardened Stainless Steel
  • We also are capable of creating abrasion resistant (AR) valves using other materials for special applications. For an abrasion resistant valve made from a special or unique material please contact us today»

The valves, seats and seals of the abrasion resistant (AR) valve are composed of several materials:

  • Duplex stainless
  • Stainless Steel
  • 8620 Alloy
  • Hardfacing stellite
  • Monel®
  • Viton® – Fluoroelastomer (For temperatures exceeding 160° F)

At Triangle Pump, we handle high and low volume orders, prototyping, and specialty production. All of our valves are proudly manufactured and tested up to the highest industry and specialty standards, including:

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

Triangle Pump handles both high and low volume orders, as well as prototyping and specialty production. In addition to these capabilities, we offer CAD design and CAM programming services to reverse engineer and manufacture parts for our customers.

Abrasion Resistant (AR) Valve Installation

To ensure the safe, proper installation of your Abrasion Resistant (AR) Valve, follow these steps:

  1. Before beginning any part of the installation, make yourself aware of all federal and state safety and environmental regulations.
  2. Safety is of the utmost importance. The pump’s power source should be completely turned off, locked out, and tagged before starting.
  3. The pump ports must be clean and free of any foreign matter, rust, or corrosion. Be sure to clean and dry the tapered part of the valve seat as well.
  4. If the AR valve comes loosely assembled or unassembled, install all o-rings and lock rings.
  5. Place the valve seat inside the pump port and press down with the palm of your hand, making sure the seat is aligned straight and level in the port.
  6. If the valve comes fully assembled with the valve cage pre-tightened, place a short wood block – big enough to cover the entire seating diameter – on top of the seat.
  7. Tap the valve seat lightly with a hammer or mallet. Under no circumstances should you use a sledge or heavy blow of any kind directly on the seat. A properly fitting valve seat will be “home” with light tapping. Pump action will seat the unit precisely and firmly through equalized liquid pressure.
  8. From top to bottom, align the valve cage, spring, and valve member.
  9. After completing the installation, turn the pump over by hand to make sure the plunger and packing are properly aligned without any obstructions.
