Stainless steel jacketed check valve flanged

This industrial grade flanged jacketed check valve is constructed from premium CF8 304 stainless steel to deliver reliable automatic backflow prevention for heavy process fluids Designed with a fully welded external heating jacket it allows hot thermal oil or steam circulation to maintain process temperatures and eliminate media crystallization around the internal disc This robust unibody construction ensures uninterrupted one way flow control for highly viscous fluids such as liquid asphalt molten sulfur polymers and heavy chemical resins
