Product Introduction

A tapered stainless passage surrounds a translating cone and spring mechanism. The cone compensates mechanically for pressure changes while the actuator selects the requested volume, separating rapid pressure response from room-level demand control.

Key Features

Mechanical compensation limits flow disturbance from duct-pressure changes.
Single body simplifies connection to one round branch.

Solutions for Your Application

Pressure fluctuations can upset room airflow offsets.

The spring-loaded cone responds to pressure independently of the electronic demand signal.

A single equipment branch needs substantial turndown.

The selected single valve spans low standby flow through its medium-flow operating range.

Available Options

Horizontal or vertical orientation
Remote electronics
