The Cameron WHEATLEY Series 500 check valve is a fire-tested carbon steel flanged end check valve with a full-open, through-conduit design for low pressure drop and less turbulence. The valve’s flanges are back-faced. This is an extra manufacturing step that provides smoother bolting surfaces and even bolt loading.
