DIAPHRAGM ACTUATOR

With eight different configurations available, there is an actuator size to meet your needs. multi-spring combinations allow for accurate selection of actuator thrust and valve for accurate selection of actuator thrust and valve travel.

FluoroSeal® Diaphragm Actuator

The simple design allows the change of action from direct to reverse acting without the requirement for extra parts, change of action can be easily made in the field. High thrust capability the moulded diaphragm and high strength casings allow for a maximum casing pressure of 6 bar, enabling a high stem thrust for a given size diaphragm.

 

Main Features

• Rugged Construction

• Severe Temperature Applications

• Compact Design

• Direct Action

• Reverse Action

• Valve Compatibility

LINED BALL VALVES

FluoroSeal lined ball valves have straight-through flow providing positive shutoff with minimal pressure drop and flow turbulence. With the ball independent of the stem, the ball has some freedom to move along the axis of the valve in the closed position, while having no freedom to rotate against the stem. When line pressure is applied to the closed ball, it moves slightly downstream to maintain contact with the downstream seat where primary sealing occurs.

FluoroSeal® PFA Lined Ball Valve

Lined ball valves can generally be installed without regard for flow direction, and are ideally suited for automation as they feature an ISO mounting pad. FluoroSeal’s standard fully PFA lined ball valve utilizes a ductile iron body housing with stainless steel ball and stem cores.

LINED BUTTERFLY VALVES

Due to its specially contoured disc profile, the FluoroSeal® fully PFA-lined butterfly valve offers high flow rates with minimal pressure drop throughout the entire range of disc rotation. Positive, bubble tight, bi-directional shut off is assured due to the elastomeric energized seat. With a standard live-loaded stem seal, tight control of fugitive emissions to atmosphere is maintained in both high cycle applications and those applications with temperature gradients. An engineered atmospheric seal at the stem prevents the ingress of foreign material into the packing chamber. Low operating torque is achieved via precision shaft bearings in combination with the spherical seat design.

Moreover, excellent corrosion resistance is provide by the GF2P lined body and the securely anchored, PFA lined disc.An integral, one piece investment cast disc-shaft core eliminates lost motion during operation. A “Double D” drive shaft and ISO 5211 mounting pad allow for easy and cost effective automation.
