VK-7213-611-4-11

The VK-7213-611-4-11 2-way globe valve assembly is engineered by Schneider Electric as part of the VB series. This component incorporates an MK-6601 pneumatic actuator that features a spring return design for reliability. The actuator is equipped with an effective diaphragm area of 50 square inches, which significantly enhances its capabilities in various control scenarios.

Operating within a nominal spring range of 3-8 psig, this assembly allows for precise adjustments to system pressure. The actuator stroke measures at a nominal length of 1/2 inch, ensuring suitable response times for applications. Air connections compatible with the actuator are 1/8 inch FNPT, which simplifies installation and integration with existing pneumatic systems.

With a flow coefficient (Cv) rating of 40, this valve assembly enables considerable fluid flow while retaining a compact design. The valve connections are designed to accept a 2-inch NPT threaded configuration for simplicity and effective utility. The valve exhibits a 2-way stem-up-open action, being normally open, which facilitates standard operational efficiency in designated systems.

The construction of the valve body consists of durable bronze, while the plug is brass, enhancing longevity. The stem is crafted from stainless steel, ensuring reliable operation across a range of conditions. Valve linkage is achieved through the AV-430 model, providing robust support, while the actuator housing is constructed from die-cast aluminum, enhancing both resilience and stability during operation.
