Part of the VG7000 series, the VG7842RT+3008EP is a 3-way mixing globe valve that excels in fluid control applications. With NPT threaded connections, installation is straightforward, and the cast bronze construction provides reliable durability.
Weighing 14.1 lbs, this valve's dimensions of 1-1/2 inches make it versatile for various setups. It uses a brass trim, ensuring proper flow management, while the integrated V-3000-8012 pneumatic actuator offers exposed access for easy maintenance and operation.
In terms of performance, the spring range operates between 9 to 13 psig, equating to 62 to 90 kPa, and supports a maximum actuator supply pressure of 25 psig (172 kPa). Operating temperatures can range from 2°C to 65°C, and it can handle fluid temperatures up to 140°C when dealing with water, along with pressures of 38 psig for saturated steam. The valve body meets ANSI B16.15, Class 250 standards ensuring robust ratings under various conditions. A minimal leakage rate of 0.01% of maximum flow complies with ANSI/FCI 70-2, Class 4, further confirming its reliability. The maximum closeoff pressures are 16 psig (110 kPa) for the normally open port and 23 psig (158 kPa) for the normally closed port.
