VG1245ER Johnson Controls Ball Valve

Overview

The Johnson Controls VG1245ER is a high-performance, two-way ball valve designed to regulate the flow of hot water, chilled water, and low-pressure steam in commercial HVAC and building automation systems. Engineered for precision modulating control, this 1-1/2 inch valve features a robust forged brass body and durable stainless steel trim. It is designed to be field or factory mounted to compatible Johnson Controls electric actuators for seamless integration into environmental control systems.

Features

• Equal percentage flow characteristic ensures stable and accurate modulating control.
• Characterized flow disk optimizes loop stability and eliminates the need for pipe reducers.
• Forged brass body provides superior mechanical strength and structural integrity.
• 300 Series stainless steel ball and stem assembly offers enhanced corrosion resistance and an extended service life.
• Dual EPDM stem seals and 15% graphite-filled PTFE ball seats provide leak-free operation.
• Maintenance-free design eliminates the need for packing adjustments or rebuilding.
