Product Introduction

A compressed-air cylinder operates the external toggle linkage on an 800 × 755 mm welded frame. The mechanism converts actuator travel into positive seal compression, providing remote isolation while retaining a mechanically locked final position.

Key Features

Pneumatic drive suits systems with an instrument-air supply.
A larger near-square opening accommodates medium critical branches.

Solutions for Your Application

The branch is beyond convenient manual reach.

The pneumatic actuator transfers the command to the external linkage.

Loss of supply energy could release seal pressure.

The final over-centre position holds the sealing mechanism mechanically.

Available Options

Solenoid valve
End-position sensing
