VG7281NT+3008DP

The VG7281NT+3008DP model from Johnson Controls serves as a robust bronze control valve coupled with a pneumatic actuator. Weighing 8.5 lbs, this valve is engineered from cast bronze material for enhanced durability in demanding environments. It is classified as a two-way valve with a normally open configuration that can be pushed down to close. Customers benefit from its union sweat end connections that facilitate straightforward integration with standard tubing.

In terms of flow characteristics, the valve utilizes brass trim and is designed for equal percentage flow, providing precise control over fluid motion. It has a nominal size of 1 inch and is rated with a control port Cv of 11.6, ensuring it can handle a substantial flow volume.

This valve's actuator is the V-3000-8012 pneumatic type, featuring an exposed design and comes equipped with a V-9502 positioner for accurate positioning control. The actuator spring operates within a pressure range of 4 to 8 psig, making it effective for various operational scenarios. Notably, the maximum closeoff pressure for this valve is 76 psig (524 kPa).

This control valve is suitable for a wide temperature range, able to operate effectively from a minimum of 2 °C to a maximum of 65 °C. For fluid media, it supports up to 140 °C for water and can handle saturated steam pressures up to 38 psig. Furthermore, it boasts a rangeability exceeding 100:1, providing excellent control flexibility across different flow rates.
