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.

ESBE VLA100 2-way and 3-way ductile iron control valve for heating and cooling control

The ESBE VLA100 controls the flow or mixes the water of a circuit with an ESBE linear actuator, as a 2-way (VLA121) or 3-way (VLA131) valve from DN 15 to DN 50. At Q-Tech we fit it with its actuator in the pre-assembled plant room, tested in our workshop before it reaches your site.

What is the ESBE VLA100?

The ESBE VLA100 is a seat control valve for heating and cooling with a ductile iron body and tight shut-off on both ports, according to ESBE. The actuator moves the stem 20 mm and the plug adjusts the water flow up to 16 bar.

What problem does it solve?

In a heating or cooling plant, the flow or supply temperature of each circuit has to follow demand. With an ESBE linear actuator, the VLA100 gives continuous control with a rangeability of more than 50, according to ESBE, and the VLA131 mixes water from two ports.

If the Kvs does not match the circuit flow, the valve works almost closed or almost open and the temperature swings. That is why the DN and Kvs should be chosen from the flow and pressure drop of your installation.

Compatibility and limits

  • Supplied without actuator: ESBE pairs it with its ALFxx1 (230 V), ALFxx4 (24 V) and ALB140 linear actuators.
  • ESBE specifies it for mixing and flow control; to divert water between two circuits, see the VLE132.
  • Media from −20 to 130 °C: heating water to VDI 2035, with glycol up to 50% or ethanol up to 28%. With 30 to 50% glycol, ESBE advises a Kvs one size larger.
  • ESBE recommends fitting it on the return where possible, not mounting the actuator below the valve and fitting a strainer upstream.
  • ESBE spare parts not included on this page: VLA901 packing box (27000100) and VLA821 adaptor kit for Siemens SQX actuators (26000700).

Frequently asked questions

Which model do I need?

It depends on the ports and the flow: the 2-way VLA121 controls flow and the 3-way VLA131 mixes. The DN and Kvs come from the flow and pressure drop of your circuit; with that data we will tell you the model.

Is the actuator included?

No. The VLA100 is supplied without actuator; ESBE pairs it with its ALFxx1, ALFxx4 and ALB140 linear actuators.

What is the difference from the VLE100?

The VLA100 is ductile iron, with internal Rp thread, tight shut-off and media up to 130 °C. The VLE100 is bronze, with external G thread and media up to 150 °C, according to ESBE.

Is it suitable for cooling?

Yes. ESBE specifies it for heating and cooling, with water and glycol up to 50%.

Can I install it myself?

It is not advisable: it should be installed by a professional following ESBE's instructions. Q-Tech supplies it fitted in the plant room or installs it with an Expert Technician.

What is the delivery time?

We have it in stock in Málaga and dispatch it as soon as we confirm your order.

Q-Tech installation and support

In the pre-assembled plant room, Q-Tech fits the VLA100 with its actuator, connects it to the controller and tests it in our workshop: it arrives ready to connect. You can book workshop pre-assembly, an on-site hourly Expert Technician or a technical call to choose the Kvs. See also our valves and accessories or message us on WhatsApp.
