Product Overview

The Pentair DE Multiport Valve, 2" Side Mount | 261152 is a complete 2" threaded multiport valve kit for Pentair side-mount D.E. filters, including the FNS and FNS Plus. One handle selects filter, backwash, rinse and the other valve positions.

This valve kit is cross-referenced to Praher SM20-2, SM2-PP2 and 27507-200-000, which helps when matching an older side-mount valve already on the equipment pad.

Ideal For

Pentair FNS and FNS Plus D.E. filters

Replacing a worn, leaking or cracked side-mount multiport valve

Equipment pads plumbed with 2" pipe

Key Features

Six-position, positive-lock operation

Dedicated winterizing position

2" threaded (FPT) ports

PVC valve body

Side-mount design for D.E. filters

Benefits

A complete valve kit lets you replace the whole multiport in one job instead of chasing leaks one part at a time. The positive-lock handle holds each setting firmly so the valve does not drift between positions.

The winterizing position makes seasonal shutdown simpler, and the PVC body resists corrosion from pool water and chemicals.

Specifications

Warranty & Compatibility

Before ordering, confirm your filter model and that your current valve is a 2" side-mount D.E. multiport. Top-mount valves and sand-filter valves are different parts. Use a thread sealant rated for PVC on the threaded ports and follow Pentair's installation instructions. Warranty is provided by Pentair under its standard terms.
