Fisher 8580 Rotary Valves Agent Original

The Fisher 8580 Rotary Valves Agent Original disk design gives it an approximately linear flow characteristic that provides precise regulation control. Valves are supplied with soft or metal seals that provide capability for enhanced stops. Sealed interchange capability minimizes parts inventory requirements. API compliant Fisher 8580 Rotary Valves Agent Original and EN standards. The valve body meets PN 10 through PN 40, CL150 and CL300 ratings.Face-to-face teaching and enhancement of the face-to-face level meet EN 593, API 609, and MSS-SP68 standards.

Product Features:

The Fisher 8580 Rotary Valves Agent Original have following features:
1.Affordable tight shutoff system – this pressure-assisted seal design enables tight shutoff of selected valves at full pressure classes.
2. Fisher 8580 Rotary Valves Agent Original are designed with shaft blowout protection.The blow-out gland is installed firmly on the valve shaft, which turns downward to form a shoulder that contacts the blow-out gland.
3. Excellent flow control — the 8580 valve has a corrected equal percentage flow characteristic and can be used for throttling applications by turning the disc 90 degrees. The adjustable ratio is 100:1
4. Affordable design with minimal dead zones — spline port connections on the drive shaft allow most Fisher rotary actuators to perform rod clamping operation.

5.Diversification of applications – Standard construction materials and sealing assemblies allow for long service life and excellent performance in a wide range of liquid and gas applications.
6.Easy maintenance – all components are interchangeable, including shaft and disc, simplifying service and reducing maintenance costs.
7.Improved Environmental Performance — The optional Enviro-SEAL packing system uses a very smooth stem surface and dynamic load design for improved sealing, steering, and load transfer. The Enviro-SEAL packing system keeps emissions below the EPA limit of 100 parts per million.
8.Simple installation – the valve body automatically aligns with the center of the pipe flange bolt, quickly and accurately aligning the valve in the pipe.
9.Reliable flange gasket surface – does not interfere with the sealing function of flat or spiral wound pipe flange gaskets by the use of seal setting screws.
