The VG7441ST+3008D is a specialized control valve from Johnson Controls' VG7000 Series, crafted from durable cast bronze. This unit weighs 17.2 pounds and is designed for two-way operation, functioning in a normally closed mode and opening by a push-down mechanism. Its dimensions include a 2-inch size, making it suitable for various plumbing configurations.

Fitted with threaded NPT connections, this valve provides a secure and effective installation. The actuator employed is the V-3000-8012 pneumatic type, which is exposed and operates within a spring range of 4 to 8 psig. Achieving a maximum closeoff pressure of 6 psig (approximately 41 kPa), this valve ensures reliability even under pressure conditions.

The trim features brass to facilitate an equal percentage flow characteristic, enhancing control precision in fluid management applications. This valve demonstrates a Cv rating of 46.2 and a Kv rating of 40.0, providing excellent flow capacity. With a rangeability exceeding 100:1, it can handle varying flow rates effectively without compromising performance.

This valve is engineered to handle a fluid temperature range between 2 and 140 degrees Celsius for water and can manage saturated steam pressures up to 38 psig. The overall operational temperature for the valve itself extends from 2 to 65 degrees Celsius. The VG7441ST+3008D control valve serves as a reliable option for controlling fluid dynamics in industrial settings.
