DIAPHRAGM DRIVEN<br />
Diaphragm-driven type actuators are recognized in the<br />
industry for longevity of service, increased sensitivity to<br />
control pressure variation and more stability and forgiveness<br />
under varying environmental temperatures.<br />
SMALL DIMENSIONAL ENVELOPE<br />
Facilitates ease of installation/maintenance and eliminates<br />
the requirement for additional support of the<br />
actuator. The actuator design provides the same<br />
dimensional envelope regardless of operation mode.<br />
THERMOPLASTIC COVERS<br />
The l/4"–2" (DN 8–50) Advantage actuator is molded<br />
from Thermoplastic polyarylsulfone (PAS). PAS is warranted<br />
to temperatures up to 300°F (149°C), is FDA<br />
compliant and is capable of withstanding caustic,<br />
chloride and alcohol washdowns.<br />
VISUAL INDICATION<br />
The Advantage actuator provides a visual indication of<br />
the valve position.<br />
DIAPHRAGM SELECTION<br />
The Advantage is designed to provide positive closure<br />
with either FDA compliant elastomer or a two-piece<br />
PTFE body diaphragm. Two piece PTFE diaphragms are<br />
more durable by design than PTFE faced diaphragms.<br />
The result is increased reliability, higher cycle and<br />
longer life.<br />
FLOUROPOLYMER “O” RING<br />
FURNISHED<br />
The “O” ring prevents cleaning and sterilizing solutions<br />
from migrating into the actuator causing premature<br />
component failure.<br />
AIR INLET CONNECTION<br />
The air inlet connections to the Advantage actuator<br />
are positioned parallel to the piping system which<br />
enhances close racking of piping. The design of the<br />
inlet ports insures zero leakage to the atmosphere.<br />
AUTOCLAVABLE<br />
The Advantage actuator is autoclavable in sizes 1/4"–2"<br />
(DN 8–50).<br />
ADJUSTABLE OPENING STOP<br />
Optional on the 1/2"–2" (DN 15–50), the Adjustable<br />
Opening Stop is an externally adjustable device which<br />
can limit the opening of the valve.<br />
OPTIONAL SEALED BONNET<br />
A “V” notch vent plug serves as a leak detector and<br />
provides a secondary containment area in the case of<br />
diaphragm failure. This is furnished upon ordering a<br />
