Belimo Z3075QS-J Valve
The Belimo Z3075QS-J Valve is a high-performance 3/4" 3-way zone valve designed for demanding commercial HVAC applications. Part of the Belimo ZoneTight (QCV) series, this valve features a 4.6 Cv rating and is specifically engineered for precise hydronic control in space-restricted areas like fan coil units, VAV reheat coils, and radiant panels. Constructed with a forged brass body and a chrome-plated brass ball, the Z3075QS-J utilizes self-cleaning ball valve technology to prevent clogging and ensure a 0% leakage rate, which significantly reduces energy loss compared to conventional zone valves.
This diverting valve is built to handle chilled or hot water systems with up to 60% glycol and maintains a body pressure rating of 360 psi. With its sweat end fittings and maintenance-free design, it allows for reliable tool-free snap assembly when paired with compatible CQB or CQKB actuators. This ensures a streamlined installation process for technicians working in tight mechanical enclosures or plenum spaces.
Key Benefits
- Superior close-off pressure performance to eliminate ghost flows in 3-way diverting configurations.
- Field-adjustable flow settings and a linear flow characteristic for optimized system balancing.
- Robust EPDM O-ring seals and PTFE seats provide high-cycle reliability in various water temperatures.
- Compact footprint with a low installation height, ideal for unit ventilators and fin tube casings.
- Maintenance-free operation with a design that resists particle debris and scale buildup.
Common Questions
What is the maximum glycol concentration for this valve?
The Z3075QS-J is rated for use with water containing up to 60% glycol, making it compatible with most chilled water and hydronic heating systems.
Can this valve be installed in any orientation?
It can be installed in any orientation from upright to horizontal. However, it should not be mounted with the stem pointing downwards to prevent moisture or debris from entering the actuator interface.
What type of connection does the Z3075QS-J use?
This specific model features 3/4" sweat (solder) connections for a permanent, leak-proof seal in copper piping systems.
