Product Introduction

Two 12-inch flow passages operate as one assembly, dividing a large branch duty across separate compensating cones. The side-by-side configuration is suited to high-volume systems where a single throat would restrict the required operating range.

Key Features

Two flow paths expand capacity within a modular assembly.
Shared support keeps the paired valve bodies aligned.

Applications

Large controlled-environment exhaust systems
Combined supply for substantial cleanroom suites

Solutions for Your Application

One round valve cannot cover the required full-flow duty.

Parallel passages provide the documented combined flow range.

Multiple separate valves complicate physical layout.

A paired assembly groups both bodies on a coordinated mounting arrangement.

Available Options

Common transition pieces
Building-management controller integration
