The VG7241LT+71CHGC control valve, part of Johnson Controls' VG7000 Series, is designed as a two-way valve that typically remains open and is activated to close via a push-down mechanism. It measures 3/4 inches in size and is made of cast bronze, which ensures robust performance under a variety of conditions.
The valve’s trim features brass and allows for equal percentage flow, providing optimal accuracy in flow regulation. With a control port Cv value of 7.3, it facilitates efficient fluid passage. The actuator used in this configuration is the VA7810-HGC-2, which operates without a spring return and is rated for a voltage of 24 VAC. It offers proportional modulating control, making it suitable for precise application scenarios.
Auxiliary switch functionality is included with two auxiliary switches, enhancing its operational versatility. This valve can withstand a maximum closeoff pressure of 289 psig, affirming its durability during high-pressure scenarios. For temperature management, it is rated to operate in environments between 2 °C and 65 °C. The seat of the valve is crafted from brass with a molded elastomeric disk, ensuring reliable sealing and longevity. The threaded NPT end connections facilitate straightforward installation into existing piping systems.
