Understanding AQ Matic Seal Kits: What’s Inside and How to Choose the Right One

Understanding-AQ-Matic-Seal-Kits

What Are Seal Kits and Why They Matter

AQ Matic diaphragm and seal kits are an important component in maintaining the life of your valve. Over time, seals can degrade for a variety of reasons. If your valve has evidence of a small leak (liquid or air service), we will typically recommend purchasing a diaphragm and seal kit.

The most common diaphragm and seal kits include the following items:

  • HYCAR Disc
  • Washer
  • O-Rings
  • Hex Nuts
  • Diaphragm

How Often Should You Replace the Diaphragm in AQ Matic Valves

It’s a good idea to keep diaphragm and seal kits on hand. The rate of replacement will depend on your system but we can estimate using the following:

  • The K52 and K53 Series are rated up to 10,000 cycles for liquid.
  • The V42 Series is rated up to 50,000 cycles for air or liquid.
  • The VAV Series is rated up to 200,000 cycles for air.
