Disclosure of Risks / Responsibility of Customer:

Fluid controls have the potential to leak unexpectedly, either to an unintended port, to the exhaust port under inappropriate conditions, or externally. Elastomeric membranes specifically have the potential to rupture due to a combination of age, cycle fatigue, and pressure.

Fluid controls may also fail closed at unexpected times, especially if the valve has been exposed to foreign debris, either ingested or formed within the valve. SELLER’s regulators are not certified to be used as a safety relief of last resort for a process vessel.

The customer acknowledges awareness of these risks, and assumes the responsibility to configure fluid systems in such a way to minimize exposure of personnel and property damage in the event of an unexpected leak or failure of SELLER’s regulators. (See Limitation of Liability).


SELLER, Inc. warrants its products against defects in material and workmanship when used in those applications approved by SELLER, for a period of one (1) year from the date of original shipment by SELLER. SELLER’s liability under its warranty shall be limited to repair or replacement, at SELLER’s option, of such defective products, F.C. A. factory.

All products are provided AS IS. The warranties provided herein are exclusive and in lieu of all other warranties. SELLER expressly disclaims all other warranties express of implied, including but not limited to the warranties of merchantability and fitness for a particular purpose.

Limitation of Liability:

Customer acknowledges and agrees that SELLER’s sole responsibility or liability in the case of any breach of the foregoing warranty, shall be for SELLER, at SELLER’s election, to repair or to provide a replacement for the product or portion thereof with respect to which such warranty contract is breached or to return all payments made by customer with respect to such product or portion thereof.

Delivery Schedule:

Delivery dates are approximate. Shipments shall be made by SELLER in accordance with SELLER’s normal delivery schedule.


Returns: All Products
  • The customer is responsible for assuring that proper packaging protects the regulators in new and reusable condition. Any damage resulting from improper packaging will be accessed by Equilibar and added to the restocking charge. All outsourced components will be subject to the SELLER, policy of a restocking fee as well as any additional charges from outsourced vendors.
  • The end user assumes all liability for ensuring that all hazardous residue is
    cleaned and removed from any products returned to Equilibar. A hazard declaration must be fully completed by end user and must accompany all back pressure regulator returns for the return to be accepted.
  • All Products will be issued a Return Material Authorization and are valid for a period of (30) days from issued and are void and unusable at the end of this.
  • All returns must be accompanied by an RMA number. Packages sent to Equilibar without an RMA number will not be accepted. The end user is responsible for shipping costs unless specified otherwise.
Returns: Back Pressure Regulators and Vacuum Regulators
  • Equilibar back pressure regulators are warranted to be free from defects in material and workmanship at time of delivery. Written notification of defect is required within 14 days of receipt for a return to be authorized. Equilibar will cover the replacement cost of any manufacturing fault (quality, design, or other) of our single use polymer products. Furthermore, suspect material may also be replaced if a root cause analysis produces reasonable evidence that supplied regulators have a defect. Equilibar’s coverage will be limited to only replacing the single use products in question (not any additional cost incurred).
  • Valves are quoted based on customer-provided application specifications; to be eligible for return, the unit must be performing unsatisfactorily within the provided application specifications.
  • Units with a standard Equilibar part number may be returned within 30 days and will be subject to a minimum 25% restocking fee. The restocking fee may be greater if any of the following conditions apply:
    • Cosmetic damage to the regulator
    • Damage to threads or working face of the regulator
    • Residue or staining from process fluids
    • Discoloration of surfaces due to high heat exposure
  • Single use polymer products are only eligible for return undamaged and unopened in original double bagged packaging. Any deviation will result in a 100% restocking fee.
  • Units with non-standard Equilibar part numbers (i.e. EQ- units) are custom parts. These units require significant engineering design time and are manufactured in small batches or individually. Due to these factors, a restocking fee of 50% is required for EQ-units returned within 30 days. EQ- units are ineligible for return beyond 30 days.
  • For valves being returned, Equilibar may request performance data including pressure set point, inlet pressure reading, and flow rate. Equilibar may also request the end user to correspond with an Equilibar engineer and attempt to resolve the issue before a return is authorized.
  • Because Equilibar valves are extremely easy to service and have only one moving part, return or repair service is rarely needed. In most cases, the end user can easily replace spare parts. This paragraph is not applicable to the single use polymer products.
Returns: Pressure Reducing Regulators
  • Equilibar’s warranty for pressure reducing regulators is one year. Units that fail within one year of service will either be replaced or issued a repair kit at no charge, subject to evaluation. Evidence of use with non-inert gases or liquids will void warranty.
  • Units in like-new condition may be returned within 30 Days of receipt. Refunds will not be issued for units that have cosmetic damage (including damage to labels) or evidence of use with non-inert gases or liquids.
  • Qualifying returns of pressure reducing regulators are subject to a 50% restocking fee.
Returns: Electronic Regulators:
  • Electronic regulators sold by Equilibar undergo three tests in two facilities before shipment: an initial calibration at the factory, a verification of the calibration at the factory, and a secondary verification of the calibration at Equilibar facilities. Because of this, factory defects reaching the end user are extremely unlikely.
  • Electronic regulator units in like-new condition may be returned within 30 Days. Refunds will not be accepted for units that have cosmetic damage (including damage to labels) or evidence of use with non-inert gases or liquids.
  • Qualifying returns of electronic regulator units are subject to a 50% restocking fee.
  • All returns must be accompanied by an RMA number. Packages sent to Equilibar without an RMA number will not be accepted. The end user is responsible for shipping costs unless specified otherwise.
  • In the event of a return, the following must be considered. Without these details, it is difficult for us to determine what might be wrong and make a speedy repair.
    • The details surrounding the electronic regulator and how it stopped working must be provided to Equilibar.
    • Did it ever operate correctly?
    • For how long?
    • Does it respond at all now?
  • It is important that Equilibar be allowed to discuss a few simple troubleshooting options with a technical contact on your end. Often a quick troubleshooting session can reveal that it is not the electronic regulator that has failed but that the electronic regulator has stopped working because of something in the system it interfaces with. Many times, we find that there is something in your application that contributes to the premature failure. Contamination, voltage transients, and ESD can all cause the electronic regulator to fail. Unless these sources are addressed first the repaired electronic regulator will inevitably fail again a short time later.
  • Even if a warranty is suspected, warranty is not proven until the electronic regulator is examined by our technicians at the factory. Therefore, all repairs must be accompanied by a purchase order that would cover the cost of the inspection should it be determined that the electronic regulator repair is not covered by warranty.
  • Expedites fees may be used to speed a repair, but expedites are not always available. The expedite fee must be paid even if the failure is determined to be under warranty. If repairs must be expedited it is Equilibar’s recommendation that a spare electronic regulator be purchased by you and kept at your location. Any replacement unit must be purchased outright before it will be shipped.
    • Loaner units or in-kind replacements are not available, even if a warranty failure is suspected. The suspect warranty electronic regulator you have cannot be traded for a new electronic regulator. Expedite fees may be paid to speed the delivery of a replacement unit, but expedites are not always available.
  • All returns must be accompanied by an RMA number. Packages sent to Equilibar without an RMA number will not be accepted. The end user is responsible for shipping costs unless specified otherwise.
Returns: Responsibility

Any product claimed to be defective must be returned by Customer prepaid for inspection. Items showing abusive or improper use, used for purposes other than intended or having been altered in any manner will not be repaired or replaced except at the expense of the Customer. Products found to be defective by our examination will be repaired or replaced at no expense to the user if such is through our omission or error.
