Keystone™ Check Valves

Figure 87L Swing Check Valves
The Keystone F87L is a resilient seated double flange rubber disc check valve for reliable reverse flow protection in sewage/water applications. Double flanged design. The flap is totally encapsulated in NBR rubber for superior sealing and corrosion resistance. The flap rises above the flow path reducing wear and allows for a flushing action during operation. All iron components are coated in fusion bond epoxy resin. Top entry cover allows for easy access for cleaning and maintenance.

Applications: Water distribution, Wastewater treatment, Wastewater collection, Water Treatment

Sempell™ Check Valves

Model 801 Swing Check Valves
Sempell controlled and uncontrolled non-return or swing check valves prevent unallowable pressure built up in the turbine coming due to back-flowing steam.

Model 801 ASME Swing Check Valves
Sempell controlled and uncontrolled non-return or swing check valves prevent unallowable pressure built up in the turbine coming due to back-flowing steam.

Model 803 ASME Swing Check Valves
Sempell controlled and uncontrolled non-return or swing check valves prevent unallowable pressure built up in the turbine coming due to back-flowing steam.

Model 803 Swing Check Valves
Sempell controlled and uncontrolled non-return or swing check valves prevent unallowable pressure built up in the turbine coming due to back-flowing steam.
