Threaded Horizontal Check Valves
A threaded horizontal check valve is a lift-type non-return valve fitted on horizontal pipes, in which the disc inside the body rises with the flow and drops onto its seat by its own weight when flow stops. As the disc moves on a straight path, it shuts off tightly.
It is used on water, heating and compressed air lines in small horizontal installations. Because of its globe-like body the pressure loss is slightly higher than a swing type; size and material are selected by model.
Main Applications
- Horizontal water distribution lines
- Heating circuits
- Compressed air lines
- After meters and devices
- Small boiler room lines

Which material? As a horizontal check valve closes by its own weight it does not work on vertical lines; choose a spring or vertical type check valve on vertical lines.
