Our standard butterfly valves can be used for air, gas, and water applications where absolute "tight" shut-off is not required. These low pressure, metal seated valves are furnished with a cast iron body and disc. Type 304 stainless steel shafts, teflon bearing, teflon packing, steel packing gland and a steel pipe plug.
Our standard valves are:
- Available in wafer or lug.
- Suitable for 25 psi differential pressure through the 12" size and 15 psi differential in sizes 14" and above.
- Designed to fit between ANSI 125/150 LB. or RPM flanges.
- Able to handle temperature from -20ºF to +450ºF.
All standard valves are available in various seat configurations to meet specific applications and service conditions. Some of the available seat designs would be: angle seat, step seat, scissor seat, clearance seat, resilient seat, o-ring seat, and tadpole seat.
(Note: These valves can also be furnished for 50 psi differential pressure with the same trim options that are available for the low pressure series.)
