The Johnson Controls VG2831TM+916GGA is an electrically-actuated, 3-way globe valve specifically designed for fluid handling. This component weighs 68 lbs and is sized at 2-1/2 inches. It ensures reliable operation across a fluid temperature spectrum of 2°C to 138°C.
Constructed from cast iron, the valve is built to meet ASME B16.1, Class 125 specifications, which guarantees its durability and resilience in various applications. It can sustain water pressures of 175 psig at 66°C and 125 psig at 138°C. For steam service, it accommodates a saturated steam pressure of 35 psig (241 kPa) at 138°C.
With a voltage rating of 24 VAC/VDC, the valve operates under a proportional control mechanism requiring a 0 to 10 Volts DC input. The closeoff pressure for this valve stands at 37 psig, ensuring secure sealing when closed. Its flow characteristic is modified linear, providing smoother flow rates based on input control signals.
The stem of this valve is made from 316 stainless steel for enhanced corrosion resistance, while the packing utilizes EPT (Ethylene Propylene Terpolymer) ring packs that offer reliable sealing and long service life. The combination of robust materials and thoughtful design makes the VG2831TM+916GGA suited for demanding fluid control applications.
