HMI ™133 SERIES
|
The HMI 133 Series Back Pressure Check Valve will allow any amount of flow, depending on line size, into the tank but closes if the flow is reversed or stopped. The flow is determined by the top female thread. This valve may also be used in other piping systems to limit the flow to one direction. A normally closed valve flow is toward the bottom male thread.
