Dwyer Instruments HBAV0724 | 2-Way ball valve | 2" NPT | Modulating | 24 VAC
Genuine Dwyer HBAV0724 electric ball valve from General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping available.
Part No. HBAV0724
Product Overview
The Dwyer HBAV0724 is a 2-way, normally closed electric ball valve with 2" female NPT connections and a modulating actuator powered by 24 VAC. It is designed for HVAC flow control and can be used in air-conditioning systems, heating systems, water treatment and production applications.
The modulating actuator accepts a 4–20 mA input, allowing the valve to hold intermediate positions for proportional flow control. The actuator operates from a 24 VAC, 50/60 Hz supply and has a power consumption of 4 VA.
The valve is rated for a maximum pressure of 375 psi (25 bar), with an 87 psi (6 bar) close-off rating. It handles process media from -5 to 50°C (23 to 122°F), while the allowable ambient temperature range is -30 to 70°C (-22 to 158°F).
Wetted materials include brass, stainless steel, NBR and PTFE. The detachable actuator includes a manual override, position switches and a visual indicator. On the 2" model, the actuator cycles through 90° in approximately 50 seconds and has a NEMA 1 (IP10) enclosure rating for indoor use.
For applications requiring a different supply voltage or control mode, compare the HBAV0724 with the Dwyer HBAV0714 and confirm compatibility with the controller before ordering.
