At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

🚀 Fast and Secure Switching (ON/OFF) for Heating/Cooling Circuits

The ESBE Series ZRS220 Motorized Zone Valve is a crucial control component designed to manage fluid flow in closed HVAC circuits. This 2-way valve uses a 2-point (ON/OFF) control actuator and features a spring return safety function.

The spring return mechanism ensures that in the event of a power failure, the valve automatically returns to its predetermined home position (normally closed or open), protecting the boiler and the system. Its robust PN16 brass construction makes it ideal for the demands of residential and commercial installations.

✨ E-E-A-T and Benefits: Flow Control with Integrated Safety

The ZRS220 series offers a flow control solution that inspires Trust thanks to its technical design and performance proven by ESBE.

  • Spring Return Safety: The spring return function ensures the valve returns to a safe position in case of any power outage.
  • Fast and Easy Maintenance: The actuator is mounted to and removed from the valve via a screw fitting, allowing for safe and simple technical service, even with the system pressurized.
  • Fast Operation: The switching time is highly efficient, with an opening time of 15 seconds and an ultra-fast closing time of 5 seconds, optimizing system response.
  • Fluid Versatility: Suitable for water and water/glycol mixtures (up to 50%), with EPDM seals ensuring chemical compatibility.
  • Manual Control: Features a side lever to operate the valve manually, facilitating the purging and initial filling of the circuit.

❓ Technical Frequently Asked Questions (FAQ)

💡 Why is the valve closing time faster (5 s) than the opening time (15 s)?

The 5 s closing time is fast because it is driven by the actuator's spring. The spring keeps the valve closed by default, and the motor is only responsible for opening it (15 s). When power is cut, the spring closes it rapidly, ensuring immediate switching.

💡 What does the PN16 stamp mean and how does it relate to 1.6 MPa?

PN16 is the Nominal Pressure, indicating that the valve can withstand a maximum pressure of 16 bar (or 1.6 MPa) at room temperature. This certifies that the brass body and seals are suitable for the typical operating pressure of central heating systems.

💡 Can I use this valve in an open domestic hot water (DHW) circuit?

No. The ZRS220 series is designed and approved only for use in closed heating and cooling circuits. For DHW and other open systems, a valve with specific certifications is required, which are not guaranteed in this series.

📞 Technical Support and Installation Advice

If you have questions about sizing (DN) or the maximum differential pressure your specific ZRS220 model can handle, contact our technical support team. We offer the Trust that only deep knowledge of the ESBE product range can guarantee.
