Product Description

The SMC Pneumatic Check Valve: Bushing (MPN AKB04B-N04S) is a pneumatics component with a brass body and 1/2 in (F)NPT connections. It features a maximum pressure rating of 1 MPa and includes NBR and aluminum alloy valve components with a stainless steel stopper.

Frequently Asked Questions

What is the SMC pneumatic check valve AKB04B-N04S used for?

The SMC AKB04B-N04S pneumatic check valve allows air flow in one direction while preventing backflow in pneumatic systems. It is commonly used in industrial automation, air preparation units, and actuator circuits to protect downstream components from reverse pressure surges.

What are the specifications of the SMC AKB04B-N04S check valve?

The SMC AKB04B-N04S check valve has 1/2 in (F)NPT connections on both ports, a brass body, NBR seals, an aluminum alloy valve, and a stainless steel stopper. Its maximum operating pressure is 1 MPa. The manufacturer part number is AKB04B-N04S.

Where to buy the SMC AKB04B-N04S check valve worldwide?

You can source the SMC AKB04B-N04S check valve through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

How to install the SMC AKB04B-N04S check valve?

Install the SMC AKB04B-N04S check valve by connecting the 1/2 in (F)NPT ports to matching male fittings in the pneumatic line. Ensure flow direction matches the arrow on the brass body. Use thread sealant on NPT threads and tighten to manufacturer torque specs. Test for leaks before system pressurization.
