VG1841ER Johnson Controls Ball Valve

Overview

The Johnson Controls VG1841ER is a 1-1/2 inch 3-way forged brass ball valve designed to regulate the flow of hot or chilled water in response to the demand of a controller in HVAC systems. Part of the VG1000 Series, this valve configuration features a chrome-plated brass ball and stem assembly and is supplied without an actuator, allowing for flexible field pairing with compatible spring or non-spring return electric actuators.

Features

• Forged brass body provides a high static pressure rating of 580 psig.
• Chrome-plated brass ball and stem handles standard water applications reliably.
• Graphite-reinforced PTFE seats backed with EPDM o-rings ensure low operating torque and long-term wear resistance.
• Maintenance-free design tested to perform leak-free in excess of 200,000 cycles.
• High rangeability of greater than 500:1 provides precise control under all load conditions.
