NOTE:

• Valves listed use a fluorocarbon o-ring for the gate seal and Buna-N o-rings for all other locations. We can supply gate valves with one or several roughing ports in a variety of locations. Please call to specify. We recommend using these valves only to 150° C in the closed position because of the performance of the o-rings.
• ASA flanged aluminum valves have flange o-ring grooves on both sides of the valve. Flange o-rings are included with valve.
