The Hayward SPX0710X32 Vari-Flo Multiport Valve is made for Hayward S200 and S240 Sand Filters and has 1.5 inch plumbing ports. This valve will only fit the S200 and S240 filter models and is not compatible with any other models. Vari-Flo multiport control valves are engineered for maximum flow at lower pressure drops. Hayward valves feature an easy-to-use lever action handle that lets you dial up to six valve/filter functions: filter, backwash, waste, rinse, closed or recirculate.
