Air Valve Mufflers & Speed Controls

How to Choose Pneumatic Speed Control Valves & Porous Metal Mufflers

• Match the port: select 1/8 NPT or 1/4 NPT male connections.

• Select the function:

• Porous metal mufflers reduce exhaust noise and diffuse air at valve or equipment outlets.

• Adjustable speed control throttles the flow to set the cylinder or actuator speed.

• Pick the build and size: brass and zinc-plated steel porous elements in compact lengths such as 1.125 in, 1.20 in, 1.45 in, and 2.19 in.

• Brands: Allied Witan Co and Ingersoll-Rand Industrial US.

Industries & Resources

These components are used in compressed-air circuits to reduce exhaust noise (porous metal mufflers) and set cylinder/actuator speed (adjustable speed control). They thread into valve or cylinder ports using 1/8 NPT or 1/4 NPT connections.

• Manufacturing:
  Quiet solenoid-valve exhaust near operators and precisely meter extend/retract rates on slides, stops, and gates for assembly and material-handling lines.

• Construction:
  Control motion on compact pneumatic actuators in portable rigs and service equipment, while muffling manifold or valve exhaust to keep jobsites quieter.

• Industrial/Packaging:
  Tune cylinder speed on diverters, cartoners, and sealers, and add mufflers to exhaust/blow-off points for lower noise around indexing and eject stations.
