Description:

Valve body has loose ANSI Flanges (Class 300, Class 150) connected via threaded adapter. Valve is available with metal or Teflon poppet. Valve material is E-coated ductile iron (or Nickel plated) with steel main spring and stainless steel poppet spring. The valve has an independent poppet to prevent back flow during operation.

Rating : The rated pressure drop is 1 psi (0.07 bar) @ 1200 scfm (34.0m³/min) airflow (valve actual operating condition is @ 100 psig (6.90 barg) inlet pressure and 180°F (82.2°C) fluid temperature).  Here a scfm is one cubic foot per minute of air at 14.696 psia (1.01325 bara), 60°F (15.555°C) and 0.0% relative humidity.

Options

Notes

1) Valve can have auxiliary ports on the outlet side and/or inlet side of the poppet.

2) Valve height can change as cracking pressure changes.

3) Valve can be ordered as a high pressure check valve. The main spring is removed, stroke set and the poppet spring is set to meet customer requirements.
