Purchase details

Product Description

The Fisher™ 8590 High Performance Butterfly Valve is engineered to provide reliable performance for both throttling and on/off control in a wide range of process applications. Designed to maintain tight shutoff, this valve can be specified for a broad spectrum of pressure and temperature conditions.

Featuring a highly optioned, single design platform, the 8590 valve helps reduce overall engineering, procurement, installation, operation, and maintenance costs. Its robust construction ensures dependable service, making it a versatile solution for various industrial needs.

Key Features & Benefits:

Multiple Shaft Connection Options: The valve can be fitted with a splined shaft for spring-and-diaphragm or pneumatic piston actuators, or with a square or keyed shaft for use with hand levers, handwheels, or pneumatic piston actuators. This flexibility allows the valve to meet diverse actuator requirements.
Tight Shutoff: The pressure-assisted seal design ensures tight shutoff, enabling the use of smaller, more economical actuators while meeting full ASME B16.34 shutoff capabilities.
Emission Control: The optional ENVIRO-SEAL™ packing system features a micro-smooth shaft surface and live loading to provide superior sealing, guiding, and load distribution, effectively controlling emissions.
Resistance to Corrosive Environments: Trim and bolting materials are available for use in sour liquid and gas applications, complying with NACE MR0175/ISO 15156 standards.
Easy Installation and Alignment: The valve body self-centers on pipeline flange bolts, allowing for quick and accurate alignment within the pipeline.
Bidirectional Shutoff: The torque required to open and close the valve remains constant, regardless of the differential pressure direction, providing true bidirectional shutoff.
