STJH-AIRTIGHT-SHUT-OFF-DAMPER-800X755-PNEUMATIC

Airtight Shut-Off Damper 800 x 755 mm Pneumatic Gas-Tight

Pneumatic shut-off for remotely operated containment branches.

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

Giới thiệu Sản phẩm

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.
