FEATURES & BENEFITS
• Double door wafer check valves permit flow in one direction only and close
automatically if flow reverses.
• They are entirely automatic in action, depending upon pressure and velocity
of flow to perform the functions of opening and closing.
• Eyebolt tapped holes, to fit eyebolts to BS EN 1S0 3226: 2010 (Eyebolts are
not supplied with valve).
