The VG7241CT+72CHGC model from Johnson Controls serves as a two-way globe control valve, constructed with threaded NPT end connections for seamless integration into piping systems. The valve has a compact size of 1/2 inches and is made from cast bronze, ensuring endurance within various operating environments.
Equipped with a brass trim for equal percentage flow, this control valve maintains excellent performance in regulating fluid movements. Its actuator (VA7820-HGC-2) operates on a spring-return mechanism, effectively delivering an actuator force output of 180 lb. This setup allows for smooth adjustments and precise control.
The control logic of the VG7241CT+72CHGC can accommodate a voltage rating of 24 VAC, while the control type allows for field-selectable options ranging from proportional control to On/Off or Floating configurations, accommodating diverse operational needs.
Designed to handle fluid temperatures between 2°C and 65°C, the valve supports a maximum fluid temperature of 140°C under conditions of up to 38 psig for saturated steam. The maximum closeoff pressure stands at 345 psig (2,377 kPa), ensuring safe operation in high-pressure applications.
The valve's body rating conforms to ANSI B16.15 Class 250, exemplifying strength and reliability. Its leakage is limited to a minimal 0.01% of maximum flow, adhering to ANSI/FCI 70-2 Class 4 standards, which indicates efficiency in maintaining system integrity.
