Heavy-Duty Marine Controls - advantages at a glance
Heavy duty, industry proven
Our Heavy-Duty pneumatic controls are our traditional devices that feature very robust designs that have been proven with decades of dependable service.
Marine Controlair® and H-Controlair® pressure graduating valves typically used for clutch and speed controls. These valves feature 1/4" NPT ports for high flow capacity, metal-to-metal valve seats for very low hysteresis, and heat-treated steel cams for extremely long service life. The marine versions of these valves also have chrome plated bronze cam housings and handles for improved appearance and additional corrosion resistance.

LogicMaster® and GearMaster® timing and sequence controls for clutch fill, engagement and power boost timing, and interlock logic.
AA and A-2-H Actuators for accurate, high force pneumatic actuation of mechanical engine governor / speed control levers.
