VB-8223-0-5-14

The Schneider Electric VB-8223-0-5-14 model functions as a 2-way globe valve body capable of controlling fluid flow with precision. Designed with a 4-inch valve size, it effectively supports a close-off capability of up to 125 psi, making it ideal for various system pressures. This valve demonstrates a flow coefficient (Cv) of 145, enabling it to facilitate significant flow rates.

Constructed with a connection type using flanges, the body is made of durable cast iron complemented with brass trim. This design ensures optimal performance and longevity in demanding environments. The stem action is configured such that when it moves up, the A port closes, effectively managing media flow.

The valve boasts an impressive ANSI Class IV rating for seat leakage, quantified at 0.01% for Port A, ensuring minimal leakage under operating conditions. Encasing self-adjusting spring-loaded packing enhances the valve’s reliability and maintains functionality. This specific valve is compatible with various media, including 25 to 50% glycol solutions, steam, and water, thus providing versatility in application use.

The flow characteristic follows a modified equal percentage curve, facilitating gradual adjustments to flow rates. It operates effectively across a temperature spectrum ranging from -7 to 138 °C. Lastly, the unit is capable of managing a saturated steam inlet pressure of up to 35 psi, making it suited for complex thermal applications.
