Johnson Controls manufactures the VG7441ST+3008E, a durable bronze control valve featuring a pneumatic actuator for fluid control applications. This valve is constructed from cast bronze and weighs 17.2 lbs, offering a sturdy option for demanding environments. It has an integrated two-way body design that remains normally closed, activating with a push-down action to facilitate flow management. The valve's size is specified at 2 inches, which allows for significant flow capacity while maintaining precise control.

The design includes brass trim that enables equal percentage flow characteristics, providing optimized flow regulation across varying conditions. The valve's Cv rating stands at 46.2, indicating its capability to handle substantial fluid volumes. Threaded NPT end connections simplify installation processes and enhance versatility for different piping setups.

A notable feature of the VG7441ST+3008E is its exposed V-3000-8012 pneumatic actuator, which is engineered to operate within a spring range between 9 to 13 psig. This actuator’s operation aligns perfectly with the valve’s requirements, especially under fluid pressures that can reach a maximum closeoff threshold of 14 psig (96 kPa).

This valve is adept at handling fluid temperatures ranging from 2°C to 140°C for water and up to 38 psig with saturated steam. Additionally, the operational temperature for the valve itself ranges from 2°C to 65°C, making it suitable for various industrial applications. Its impressive rangeability, rated at greater than 100:1, ensures that this valve can perform well across a diverse range of flow conditions.
