VK4-7223-303-4-11

Designed for precise fluid control, the Schneider Electric VK4-7223-303-4-11 is a 2-way globe valve assembly paired with an advanced pneumatic actuator model MK-4621. This setup features a spring return mechanism that guarantees reliable performance by repositioning positively.

The valve's effective diaphragm area measures 11 square inches, which aids its responsive action across a wide operational temperature spectrum extending from -29°C to 104°C. Conversely, the storage capability remains robust within a range of -40°C to 104°C, ensuring functionality even in extreme conditions.

The design supports a nominal spring range between 10 to 13 psig and requires an air supply pressure of up to 30 psig, confirming it can handle demanding operational scenarios. At a nominal actuator stroke of 1/2 inch and a flow coefficient of 40 Cv, the valve efficiently regulates flow through a 2-inch NPT threaded connection, marking it suitable for various installations.

This 2-way valve operates in a stem-up-closed (normally closed) fashion, promoting effective isolation when not in use. Constructed from bronze for the body, coupled with a brass plug and a stainless steel stem, the assembly ensures resilience and longevity even amidst harsh environments. The valve linkage is provided by the AV-401 type, while the actuator housing is made of die-cast aluminum, further enhancing the overall durability of the assembly.
