API609 Cast steel Butterfly valve 150#
Technical Requirement:
- Inspection and test API 598
Actuator Flange: Accommodates all types of actuators, handles, gear operators, electric actuators, and pneumatic actuators.
Bushings: Stem bushing reduces torque and isolates the stem from the valve body, preventing seizure of the stem due to corrosion in the stem journal baring.
Precision Profile Disc: Provides bubble-tight shut-off and assures minimum torque and longer seat life.
Shaft Weather Seal: (Below bushing on some models)
Seat Face: Eliminates need for flange gaskets.
Phenolic Backed Seat: Non-collapsible, stretch resistant, blow-out proof, field replaceable.
Butterfly valves are used to shut off or regulate the flow of fluids (isolation and regulation). For low pressure and non-critical applications, API 609 center butterfly valves (soft seal) are preferred over gate and ball valves because they are cheaper, lighter, and easier to install. Eccentric butterfly valves with metal seats (double and triple eccentric valves) are becoming increasingly popular and compete with globe and ball valves in some applications.
