GHIBSON
Frequently asked questions
Common questions about GHIBSON from 3G Electric.
What are the pressure and temperature ratings for GHIBSON ductile iron butterfly valves?
GHIBSON ductile iron general-service butterfly valves are rated for a maximum cold working pressure of 250 psi. Temperature limits depend on the seal material: FKM seals typically handle up to 400°F (204°C), while Buna-N seals are suitable for up to 212°F (100°C). Always refer to the specific product datasheet for exact temperature-pressure derating curves.
What media are GHIBSON butterfly valves compatible with?
GHIBSON butterfly valves are designed for use with combustible gases, natural gas, steam, and water. The choice of seal material affects compatibility: FKM seals offer resistance to a wide range of chemicals and high temperatures, while Buna-N seals are suitable for water and general service. For specific media, consult the chemical resistance guide or contact 3G Electric for assistance.
What actuation options are available for GHIBSON butterfly valves?
GHIBSON butterfly valves are available with bare stem, lever handle, or gear-operated handwheel. Bare stem models are intended for mounting an actuator, such as pneumatic or electric, using the ISO 5211 mounting pad. Lever handles provide manual quarter-turn operation, while gear operators offer mechanical advantage for larger valves or higher pressure drops.
Are GHIBSON butterfly valves NSF certified?
Some GHIBSON butterfly valve models are NSF certified for use in potable water systems. Certification depends on the specific model and materials. Check the product datasheet or contact 3G Electric to confirm NSF certification for the valve you require.
What are the available sizes for GHIBSON ductile iron butterfly valves?
GHIBSON ductile iron general-service butterfly valves are available in pipe sizes ranging from 3 inches to 20 inches, as shown in 3G Electric's catalog. This range covers common industrial piping sizes. For sizes outside this range, contact 3G Electric to check availability.
