    ESBE control valves for HVAC: PN16 2-way and 3-way seat valves

    A seat control valve is a 2-way or 3-way linear valve that, driven by an actuator, controls the flow or temperature of a heating or cooling circuit. In this subcollection of ESBE valves we bring together the ESBE control valves for boiler rooms, commercial HVAC and processes, in stock in Málaga.

    The valves are supplied without actuator: ESBE pairs them with its ALFxx1 (230 V), ALFxx4 (24 V) and ALB140 linear actuators. Ask us for the actuator for your valve.

    How to choose the control valve

    1. Connection: external G thread, the VLE100; internal Rp thread, the VLA100.
    2. Function: the 2-way valve controls flow; the 3-way valve mixes. To divert water between two circuits, the VLE132, with a maximum differential pressure of 50 kPa according to ESBE.
    3. Kvs: it comes from the flow and pressure drop of the circuit. With 30 to 50% glycol, ESBE advises a larger Kvs. Below 0 °C, add the ALF802.

    For domestic circuits with rotary valves, see ESBE mixing valves.

    Applications

    • Boiler rooms and heat generation in buildings.
    • Comfort cooling with water or glycol mixtures.
    • Ventilation, district networks and processes, according to ESBE.

    Why rely on Q-Tech for your plant room?

    1. We fit the valve with its actuator and controller in the pre-assembled plant room, tested in our workshop before it reaches your site.
    2. With a technical call we choose the DN and Kvs with your circuit data, and an on-site Expert Technician installs or checks it.
    3. The valves are in stock in Málaga, and we answer you on WhatsApp.

    Frequently asked questions

    Is the actuator included?

    No. ESBE supplies them without actuator and pairs them with its ALFxx1, ALFxx4 and ALB140 linear actuators.

    What is the difference between the VLE100 and the VLA100?

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

    Are they suitable for cooling?

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

    What is the delivery time?

    They are in stock in Málaga and we dispatch them as soon as we confirm your order.

    Choose the valve by its connection and Kvs and control your circuit with ESBE and Q-Tech.
