Working Mechanism

  • Check valves use a poppet mechanism that allows fluid or gas to flow in one direction and blocks it in the opposite direction.
  • When fluid or gas flows in the desired direction, the poppet is pushed away from the seat, allowing the flow to pass through the valve unimpeded.
  • But when the flow tries to reverse, the poppet is forced back against the seat, blocking the flow and preventing backflow.

Features

  • Eaton check valves can handle flows up to 151 litres per minute and pressure up to 210 bar.
  • They feature steel construction to withstand temperatures ranging from -40 to 120 degrees C.
  • These direct-acting valves have Buna-N seals that minimise leaks.
  • They can connect and regulate flows from two different pipes.

Frequently Asked Questions

What type of fluids can these valves tolerate?

These valves can handle all general-purpose liquids and gases.

How do I choose the right check valve for my application?

To choose the right check valve, consider factors like the type of fluid / gas to be used, the pressure & temperature of the system, the flow rate and the size of the valve.

How do I maintain a check valve?

Maintenance for check valves involves regular inspection, cleaning and replacement of worn or damaged parts.

How to install these valves?

  • Turn off the system and relieve any pressure before installing the valve.
  • Identify the correct port locations for the valve.
  • Screw the valve into the designated port until it is hand-tight. Do not use tools to tighten the valve, as this could damage threads.
  • Once the valve is installed, turn the system back on and check for leaks.
