Siral CVW Series

The CVW is a characerized control ball valve designed specifically to improve the overall capabilities of a control valve. The CVW sets new standards in control accuracy, leakage efficiency and life durability.

Stability and Control

• The valve’s equal percentage characteristic provides a linear change in thermal output based on the valve’s opening angle that is controlled by the actuator’s input signal.
• With its built-in stainless-steel ball and brass disc, the CVW is designed to provide durability and flow accuracy that are lacked in other plastic disks lack.
• The brushless DC motor technology has longer life due to its low friction design.
• The valve is designed with efficiency in mind. It incorporates a leak-free auto-cleaning ball assembly. Its thermal barrier flange reduces heat-transfer to the actuator extending its life.
• Internal leakage in a valve causes energy waste. Most 3-way valves in the industry usually have some level of internal leakage even when new. With our unique valve design both our 2-way and 3-way valves are bubble tight with zero leakage through all ports.
• Brushless motor technology improves efficiency due to reduced heat output compared to conventional motors.
• The CVW has a large range of Cv options for each valve size. This reduces installation costs created by multiple pipe reductions.
