VK4-7313-303-4-11

The VK4-7313-303-4-11 is a 3-way globe valve assembly from the Schneider Electric VB Series, suitable for various fluid control applications. This component employs a pneumatic actuator model MK-4621, which features a spring return mechanism, allowing for consistent positioning through its positive positioner. The effective diaphragm area measures 11 square inches, ensuring responsive action when regulating flow.

Designed for a broad operating temperature range from -29°C to 104°C, the valve assembly can also withstand storage temperatures from -40°C to 104°C. The nominal spring range operates between 10 to 13 psig, with a maximum air supply pressure capped at 30 psig, providing flexibility for different system setups. The actuator stroke is set at a nominal 1/2 inch, making it compatible with various applications.

For fluid dynamics, the assembly features a flow coefficient (Cv) rated at 41, which enhances its capability to mix flows effectively. The valve's connection size is 2 inches with NPT-threaded fittings, making it easy to install within existing systems. Constructed with a bronze body, a brass plug, and a stainless steel stem, the assembly is designed for longevity and resistance to corrosion, while the actuator housing is made of die-cast aluminum for added strength. This ensures that the valve assembly holds up in rigorous operating conditions, making it a reliable choice for controlling various types of fluids.
