## Long description

Honeywell V135-3/4B is a compact dividing and control valve with an internal 3/4" thread and a flow coefficient kv = 3.2. Built for hydronic heating and cooling systems, this valve enables controlled flow splitting and fine regulation in distribution circuits. Its 3/4" internal thread makes it compatible with common plumbing fittings and manifolds used in residential and light commercial installations.
Advantages
The valve offers stable hydraulic performance and precise flow control thanks to its defined kv value. Its compact design and standard internal 3/4" thread simplify installation into existing manifolds and mixing assemblies. Constructed for system reliability, the valve supports consistent operation in heating and cooling circuits and helps maintain balanced flow between branches.
Suitable for
Hydronic heating manifolds and distribution circuits
Cooling system distribution panels
Mixing stations where flow division and regulation are required
Retrofit projects using standard 3/4" fittings
Key specifications
Connection type: internal 3/4" thread
Flow coefficient (kv): 3.2
Function: dividing / control valve for flow splitting and regulation
Application: hydronic heating and cooling distribution
Installation: inline within manifolds, mixers, or distribution circuits
How to use
Install the valve into the distribution line or manifold using compatible 3/4" fittings, ensuring thread sealing appropriate for the system medium. Position the valve to allow access for adjustment or servicing. Use the valve to regulate flow between branches by adjusting to the required setting for hydraulic balance. Verify system pressure and temperature limits of the installation before commissioning and perform leak tests after assembly.
Usage recommendations
Use the valve in systems that match its hydraulic characteristics and connection size; confirm compatibility with the system fluid, operating pressures, and temperatures. During installation, follow standard plumbing practice for thread sealing and support piping to avoid strain on the valve body. Periodic inspection for leaks and correct function is recommended as part of routine system maintenance.
