ITT actuation choices for reliable valve operation.
A diaphragm valve is only as useful as the hardware operating it. Triplex helps match manual bonnets, pneumatic actuators, stainless actuator options, fail position, feedback, and service access to the way the valve actually runs in the plant.
Manual bonnets and topworks
Actuation selection should be tied to valve size, diaphragm material, process pressure, available air, fail position, control feedback, washdown exposure, and maintenance access.
Manual bonnets and topworks903 Cast Iron Manual
The 903 cast iron manual bonnet is a practical manual topworks option for Pure-Flo valve packages where the service does not require stainless external hardware.
Manual bonnets and topworks913 Stainless Steel Manual
The 913 stainless steel manual bonnet is selected when washdown, corrosion resistance, and sanitary plant expectations make stainless external hardware the better fit.
Manual bonnets and topworks963 Manual
The 963 manual bonnet is a familiar Pure-Flo handwheel option for valves that need reliable operator control and straightforward maintenance access.
Manual bonnets and topworks963 Colored Handwheel
Colored handwheel options help maintenance and operations visually identify lines, products, cleaning circuits, or critical valve functions.
Manual bonnets and topworks970 Stainless Steel Manual
The 970 stainless steel manual topworks option belongs in hygienic environments where corrosion resistance and clean external hardware matter.
Manual bonnets and topworksBio-Pure Manual Bonnet
Bio-Pure manual bonnets support compact high-purity valve assemblies where the valve package is smaller but the process expectations are still serious.
Manual bonnets and topworksBio-Tek Manual Bonnet
Bio-Tek manual bonnets are reviewed for small high-purity valve configurations where space, documentation, and precise manual operation all matter.
Pneumatic Advantage actuators
Actuation selection should be tied to valve size, diaphragm material, process pressure, available air, fail position, control feedback, washdown exposure, and maintenance access.
Pneumatic Advantage actuatorsAdvantage 2.1 Actuator
Advantage 2.1 is the current pneumatic actuator conversation for many smaller Pure-Flo valve sizes when automation, cycle life, and serviceability matter.
Pneumatic Advantage actuatorsAdvantage Actuator
The Advantage actuator platform is the core pneumatic actuation option for automated Pure-Flo diaphragm valves.
Pneumatic Advantage actuatorsAdvantage Actuator Series 33
Series 33 actuators are reviewed when valve size, diaphragm material, process pressure, or fail-position requirements call for a different actuator force range.
Pneumatic Advantage actuatorsAdvantage Actuator Series 47
Series 47 actuators support higher-force pneumatic actuation needs on larger or more demanding diaphragm valve assemblies.
Pneumatic Advantage actuatorsAdvantage Compact Stainless - ACS Actuator
The ACS actuator is a compact stainless pneumatic actuator option for tight installations and hygienic environments.
EnviZion, BioViZion, and PfuZion bonnets
Actuation selection should be tied to valve size, diaphragm material, process pressure, available air, fail position, control feedback, washdown exposure, and maintenance access.
EnviZion, BioViZion, and PfuZion bonnetsEnviZion Manual Bonnet
The EnviZion manual bonnet keeps the EnviZion platform serviceable when the valve does not need automated actuation.
EnviZion, BioViZion, and PfuZion bonnetsEnviZion Actuated Advantage Bonnet
The EnviZion actuated Advantage bonnet pairs the EnviZion valve platform with pneumatic operation for automated process control.
EnviZion, BioViZion, and PfuZion bonnetsEnviZion Actuated Stainless Steel Bonnet
The stainless actuated EnviZion bonnet is reviewed when the installation needs pneumatic operation and stainless external hardware.
EnviZion, BioViZion, and PfuZion bonnetsBioviZion Manual Bonnet
BioViZion manual bonnet selections should be tied back to the complete BioViZion valve package and the process expectations around it.
EnviZion, BioViZion, and PfuZion bonnetsBioviZion Actuated Bonnet
BioViZion actuated bonnets support automated bioprocess valve applications where cleanability, documentation, and controls alignment all matter.
EnviZion, BioViZion, and PfuZion bonnetsPfuZion Bonnet Assembly
PfuZion bonnet assembly selection should be reviewed as part of the full EnviZion-family valve package, not as an isolated hardware item.
What Triplex will verify before quoting.
Triplex reviews the complete valve package so the recommendation fits the process, the plant, and the maintenance reality.
| Selection point | Why it matters | Triplex note |
|---|---|---|
| Manual vs. pneumatic | Operator access, cycle frequency, safety, and automation requirements drive the choice. | Do not pick actuation without understanding how the valve is used. |
| Fail position and sizing | Fail-open/fail-closed behavior and actuator force depend on the full valve assembly. | Confirm valve size, diaphragm, pressure, and air supply. |
| Feedback and service access | Switch packages, position feedback, and washdown exposure can change the best hardware choice. | Triplex can coordinate actuator and controls conversations together. |
