The VG7441RT+823E00 from Johnson Controls is a robust 2-way globe control valve known for its reliability and functionality. This normally closed valve features a 1-1/2 inch diameter and is constructed from durable cast bronze, allowing it to withstand demanding conditions. Designed for precise fluid regulation, it employs NPT threaded connections for secure integration into piping systems.
Weighing in at 19.0 lbs, the valve is equipped with an MP82 pneumatic actuator, which features a 25 square inch diaphragm and operates on a spring-return-up mechanism. This actuator facilitates an effective stroke of 3/4 inch (19 mm) and maintains a spring range of 9 to 13 psig (62 to 90 kPa), granting users flexibility in pressure settings.
The actuator supply pressure can reach a maximum of 25 psig (172 kPa), making it suitable for various operational environments. The valve is capable of handling an operating temperature range from 2°C to 65°C, ensuring efficiency in diverse settings. It supports a maximum fluid temperature of 140°C, making it appropriate for hot water applications, while also handling saturated steam pressure up to 38 psig.
The VG7441RT+823E00 has a body rating of ANSI B16.15, Class 250, assuring its durability and strength in service. In terms of performance, it exhibits an impressively low leakage rate of just 0.01% of maximum flow, conforming to ANSI/FCI 70-2, Class 4 standards. This valve achieves a maximum closeoff pressure of 79 psig (545 kPa), ensuring operational effectiveness in controlling fluid flow.
