  • The 693 Series Poppet Check Valve incorporates a thin elastomer disc supported by a poppet that seals on the seat.
  • Pressure in the flow direction moves the seal off the seat at about 1/3 psi before pressure builds enough to move the poppet away from the seat.
  • The 693 Series Check Valve maximum operating pressure of 125 psi covers a wide range of air and fluid applications.
  • The 693 Check is a compact design with a light cracking pressure, high flow rate, and a positive seal at very low back pressure or slight vacuum.
  • For  cracking pressure applications 1 psi and higher, an embedded o-ring poppet is substituted for the standard elastomer disc poppet.
