Products Decription:
1. Lower torque ratings
enable the use of smaller, less expensive actuators.
2. The seal to atmosphere
is assured by using the triple PTFE O-rings around the base of the shaft.
3. A wide sealing face
prevents leakage at the flange.
4. Improved disc design
assures better stability.
5. Temperature Range
0° to 400° F 233 K to 453 K -20°C to 200°C
6. Pressure Range
Suitable for vacuum service (0.02 psi/1,33 hPa) Shut-off Pressure max. 150 psi/10 bar.
7. Direct mount actuation
ensures robust performance while providing compact system design.The large standard mounting pad conforms to ISO 5211.
8. Both the body and the shaft lining
continue past the PTFE-ring stem sealing components. The shaft and the seal components are protected from the flow media .
9. Better atmospheric corrosion resistance through high-end surface coating.
