Valve is normally open. Valve body has a 5.0 inch inlet OD and 7.75 inch outlet OD flange sized to adapt to a 4 or 8 bolt pattern. The inlet and outlet are in line. The poppet seals with special Teflon o-ring mounted in the body. Valve material is a ductile iron body, aluminum poppet and piston with steel main spring and stainless steel poppet spring. The valve has an independent poppet to prevent back flow during operation and at shutdown.
