Cordis Pressure Controls FAQ

Is the output pressure of the Cordis linear?

A: Yes, within +/- .05% BFSL of

How can I electronically control the Cordis?

A: The Cordis can be commanded with 0-10 VDC (standard) or serial communication. (Capable of 0-5 VDC for specials only)

Are there other plumbing options available?

A: The Cordis is available in 1/8" NPT or G 1/8". (Manifold mount for specials only).

Can PID changes be made in the field?

A: Yes. Refer to the IOM for command sets needed to accomplish this.

Can Cordis be calibrated 0 to 5.00 VDC instead of 0 to 10.00 VDC?

A: Yes, but under a special part number (Would result in a custom part number.)

Can the output pressure of the Cordis be customized?

A: Yes, with more detailed application specifications (Would result in a custom part number.)

Can flow of the valves be customized?

A: Yes, with more detailed application specifications.

What is the lowest full scale calibrated range of the Cordis?

A: 0-10" H2O full scale is available with a custom part number

Where can the Cordis be purchased?

A: From your local Clippard Distributor

Does the Cordis require a constant bleed orifice to function accurately?

A: No

Is the housed Cordis unit IP65?

A: Yes

Are the calibrated pressure ranges based on sensor ranges?

A: Yes. There are 7 ranges currently available as a standard product.

Will the Cordis unit be able to have external sensor feedback?

A: The Cordis was designed to work with an external sensor instead of the integrated sensor element on the PCB as a customer specific special. Clippard will need sensor details to qualify the specifications.

Can the Cordis unit work with vacuum?

A: Yes, as a special.

Will the Cordis product have multi-station manifolds available?

A: Multi-station manifold capable as a special.

The Cordis unit's flow capability is based on the capabilities of the EVP and DVP series valves. Is there or will there be an option to increase the flow capabilities?

A: Yes. Cordis will need to be coupled with a larger regulator or booster. Standard accuracy specifications will not apply.

Is there a program available for re-calibration in the field?

A: No. Not at this time.

Will the Cordis unit be capable of performing at higher pressures above 150 psig?

A: Special Orders

Will there be a digital display option for either the card or housed unit?

A: Not at this time.

What is meant by "serial communication"?

A: Serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. (Digital communication)

Can the calibrated output range be inverted?

A: Yes. Specials only.

Can the Cordis unit be used with water type media?

A: No. Clean, dry, inert gases only.

Can the Cordis unit switch between Static and Dynamic flow and still maintain control and stability?

A: Yes, to a certain level of flow. This is valve and application dependent.

Will there be a traceable calibration document per unit?

A: Yes. Each unit will be calibrated before release. Please contact us if you would like the calibration document. Please have your serial # on hand when contacting us to retrieve this record.

Are there any mounting or vibration concerns with the Cordis unit?

A: No for mounting. Vibration will need to be tested.

Will the online configurator help me configure a special calibration, or what is the process for this?

A: For specials, please contact Clippard or your local Clippard Distributor.

What types of materials are available for the Cordis manifold?

A: Aluminum is standard. All other materials are specials.

What is the recommended filtration for the Cordis unit?

A: 40 micron on the supply side.

What is the recommended supply pressure to the Cordis unit?

A: Inlet pressure needs to be 10% higher than the maximum calibrated range of your Cordis. Refer to the Operating Instructions for max. inlet pressure per calibrated range.

Is there a preferred sealant to use when applying fittings?

A: Preferred is Loctite 545 or equivalent.

Is the exhaust port threaded?

A: Yes. CPCC has 10-32 port. CPCH has a 1/8" NPT (G1/8)

What is the resolution of the Cordis unit?

A: The Cordis can respond to command signal changes of 5 mV.
