NPT Threaded - Pressures to 15,000 psi (1034 bar)
Prevent reverse flow where leak-tight shut-off is not mandatory. When differential drops below cracking pressure, valve closes. With all-metal components, valve can be used up to 800°F (425°C). See Technical Information section for connection temperature limitations. (Not for use as relief valve.)
Ball and poppet are an integrated, one-piece design to assure positive, in-line seating without "chatter". Poppet is designed for axial flow with minimum pressure drop.
Cracking Pressure: 20 psi (1.38 bar) +/- 30% No optional cracking pressures available.
With All-Metal components, valve can be used to 800°F (425°C).
Minimum standard operating temperature is -110°F (-79°C).
For Low Temperature operation below 0° to -423°F (-18 to -252°C) use suffix "-LT" (Low Temp Spring)
Installation: Vertical or Horizontal as required. Flow Direction arrow on valve body
