Valve Solution’s Series V High Performance Segmented Ball Valve is a high capacity control valve with precise control?and superior close-off for liquid, gas and steam applications.
The VSI’s Series V high performance ball valve is ideal for high pressure high flow service where control is a priority.? The ?V? notched stainless steel ball allows for a very high control range for this equal percentage flow characteristic valve.? The soft seat TFM material also enables the valve to close off with class VI rating which means ?zero leakage?.
Sizes range from 1? to 12? for large flow applications where butterfly valves don?t adequately control.? The 1? thru 2? valve bodies are multi-rated for ANSI 150 and ANSI 300. For sizes 3? and larger, ANSI 150 and ANSI 300 are available.

Additional Product Information
To reduce headaches and simplify installation, the Series V segmented control valve is available with either a flangeless wafer style body with NPT threads or an integral double flange body.
With lay lengths conforming to common industry standards the Series V can be used to easily replace other valves including obsolete linear globe valves.
Designed for Automation
The Series V, from design brief to over 10 years of production, has been designed specifically for automation of all varieties in HVAC control applications.
The standard mounting plate for actuators and square or double-D type shafts allow mounting of all VSI or third party actuators to meet any project requirement.
The single seat design and offset actuation of the valve ensure low operating torque allowing for a more broad and cost effective choice of automation.
Special configurations such as 3-way assemblies, spring return actuators, or explosion proof accommodations are available through Valve Solutions or your Authorized Reseller.
Easy Inspection and Service
With an in-line replaceable packing and a seat that only requires simple hand tools to replace, the Series V is designed to ensure that the valve lasts for the life of the system with little or no downtime.
The heavy duty TFM seat and stainless backup ring can be removed and inspected by removing as little as two screws then pulling them from the body by hand. For double flanged and NPT installations a full seat replacement can be preformed with the valve in-line by removing an upstream pipe segment or fitting.
A self adjusting spring loaded set of PTFE packing rings requires no preventative maintenance.
Packing replacements are a painless affair, with the available packing service kit containing all necessary parts including the packing rings, o-rings, and even the spanner wrench for the packing gland.
A complete packing replacement can be preformed with the valve remaining in the line, and without draining the line in most cases.
The characterized “V” port type notched ball of the Series V is designed to provide a modified equal percentage flow curve. This flow characterization matches well in coil and temperature control applications, both modern and as retrofit for obsolete or damaged control valves such as globe valves.
The high 300:1 turn down rangeability ensure that each valve can be used for flow control over essentially its entire range of travel with minimal cavitation and noise.
Designers utilizing the Series V are able to create systems with wider swings in flow than traditional control valves while still maintaining the accuracy required by modern building automation packages.
