Wholesale PricingThe Amerex 10147 Pneumatic Actuator, also called the control head, is a core component used in nitrogen-actuated Amerex fire suppression systems including the Amerex Industrial (IS) dry chemical and KP wet chemical kitchen systems. Made of extruded brass, this device mounts directly to the top of the agent cylinder's discharge valve. When the system triggers, nitrogen pressure from the actuation cartridge (12856) enters through the 1/4-inch NPT ports, pushing a piston inside the actuator that depresses the valve stem and releases the suppression agent. In plain terms: it's the device that physically opens the cylinder valve and gets the agent moving when the system fires.
The pneumatic actuator is the mechanical interface between the nitrogen actuation signal and the agent cylinder valve. Its design requires no electrical power; it operates purely on nitrogen gas pressure, making it inherently reliable in environments where electrical failures might compromise electronic actuators. The machined brass construction provides durability in industrial and commercial kitchen environments where the actuator is exposed to heat, vibration, and occasional grease contamination.
The 10147 mounts to the cylinder valve's discharge port, so when nitrogen pressure is applied it directly depresses the valve stem to initiate discharge. Inspect the actuator at every semi-annual NFPA 17A inspection. Check the 1/4-inch NPT ports for blockage, verify the piston moves freely, and look for any corrosion or physical damage. After any system discharge, the actuator should be inspected before re-arming and replaced if any deformation is found. Available through authorized Amerex distributors.

At every semi-annual NFPA 17A inspection, check the 10147 actuator for corrosion on the brass body and NPT ports, verify the actuation ports are unobstructed, and confirm the piston mechanism moves freely. In kitchen environments, grease can accumulate in the 1/4-inch NPT port and partially obstruct the nitrogen actuation path; clean if any accumulation is found. After any system discharge, inspect the actuator for deformation from the discharge event. Replace with a new 10147 if any damage is found. Do not return a deformed actuator to service. Document condition in the fire suppression system inspection record.
Is the 10147 the same as the ANSUL regulated actuator (429850 or 418691)?
No. The 10147 is an Amerex pneumatic actuator for IS and KP system cylinder valves. The ANSUL 429850 and 418691 are regulated actuators for ANSUL Automan systems. They use different valve interface geometries and actuation pressure specifications and are not interchangeable. Always use the actuator specified by the system manufacturer for your specific installation.
Does the 10147 come with the nitrogen actuation cartridge?
No. The nitrogen actuation cartridge (12856) is sold separately. The 10147 is the actuator body that mounts to the cylinder valve. The 12856 nitrogen cartridge provides the gas pressure that the 10147 uses to open the valve. Both components are required for a complete pneumatic actuation assembly.
