Check Valves
Ball Check Valves are ideal when leak tight shut-off is not necessary. This valve uses no elastomers and employs a metal to metal seal. The temperature range for the Ball Check Valves is -420° F to 1200° F (-251° C to 648° C). Available in pressures up to 100,000 PSI (6895 bar).
The O-Ring Check Valves reliably prevents backflow where leak-tight shutoff off of liquids or gases is required. The standard construction uses a Buna-N o-ring, the O-Ring Check Valve is also available with the following O-rings: Viton, PTFE and Kalrez. Temperature ranges for the O-Ring Check Valve are: Buna-N -65° to 250° F (-54° to 121° C); Viton -40° to 500° F (-40° to 260° C); Teflon -320° to 400° F (-195 to 204° C); Kalrez -25° to 550° F (-29° to 288° C). Available in pressures up to 100,000 PSI (6895 bar).
