Features
- The pressure-assisted seal design provides tight shutoff against the full pressure rating of the specified valve.
- The anti-blowout gland fits securely over the valve shaft, which has been turned down to form a circumferential shoulder that contacts the anti-blowout gland.
- A splined end connection on the drive shaft allows lever clamping by most Fisher rotary actuators.
- Optional keyed shaft is ideal for on/off applications and allows actuator selection flexibility.
- The optional ENVIRO-SEAL™ packing system is designed with very smooth stem surfaces and live-loading provides improved sealing, guiding, and loading force transmission.
- The valve body self-centers on the line flange bolts as a fast, accurate means of centering the valve in the pipeline.
- Seal retainer screws are located so there is no interference with the sealing function of either flat sheet or spiral-wound line flange gaskets.
POSI-SEAL A31D and 8580 & 8532 Valve Comparison
The following sections are intended to provide a nominal comparison between the Fisher POSI-SEAL A31D valve and the Fisher 8580 & 8532 valves.
Scope, Size, and Class
Sizes NPS 3 – 24 CL150 and 300 of the A31D valve will be made obsolete and replaced with the 8580 and 8532 valves in equivalent size and class. The 8580 valve covers NPS 3 – 12 and the 8532 valve covers NPS 14 – 24.
Capacity (Cv)
The flow capacity of the A31D valve is not equivalent to the 8580 valve. However, the A31D and 8532 have identical flow coefficients. Please see Catalog 12 Section 1.
Actuator Sizing (Torque)
The actuator sizing for the A31D valve and 8532 valve is the same. The sizing coefficients, breakout torque, and dynamic torque are also the same.
The actuator sizing for the A31D and 8580 are different. Please see Catalog 14 Sections C & D.
