Specline^® Damper

Regulators

Specline Damper Regulators

Specline Regulators are designed for minimum leakage applications. Each regulator is comprised of a frame, an indicator handle, a serrated cast alloy core and a cast alloy nut. Serrations on the cast alloy core mesh with serrations in the frame to firmly lock the regulator in position. A spring washer situated between the core and the cast frame allows for smooth non-binding adjustment. A wedge pin is used to eliminate rattle and take up slack between regulator and damper shaft.

•All SR and SRH type regulators include a cast alloy frame and a neoprene frame gasket.
•The SRHS and SRS utilize a stamped frame and include a neoprene frame gasket.
