Butterfly Valve Spacers


Valve spacers are required when the opening of the inside diameter of the pipe is smaller than the diameter of the open valve disc. This can occur with some sizes of poly pipe. As the butterfly valve disc rotates, it may hit the ID of the poly stub flange. In some instances, JAG Poly can machine stub flanges to avoid using spacers and provide for full butterfly-valve opening. Valve spacers are used to off-set the standard HDPE flange face to provide for full wafer rotation, when machined flanges cannot be used.
