Products Decription:

1.Lower torque ratings

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.
