Johnson Controls VG7000-1007 Spring Kit

The Johnson Controls VG7000-1007 is a specialized field mounting spring kit designed for heavy-duty pneumatic actuation in commercial HVAC systems. This 3-6 PSI spring range kit is engineered specifically for 1-1/2" and 2" (DN40 and DN50) VG7000 series bronze valve bodies featuring a 3/4" stroke (19 mm). Built to provide precise mechanical tension for V-3000-8001 pneumatic actuators, this kit ensures reliable normally open (PDTC) or normally closed (PDTO) valve positioning based on your specific control sequence requirements.

Constructed for simplified field installation, the VG7000-1007 includes the high-tension spring, upper spring seat, stem extension, and critical locking hardware necessary to restore or modify actuator performance. This kit is essential for technicians managing proportional control of hot water, chilled water, or saturated steam. By maintaining the V-3000 series actuator with the correct spring rate, you ensure accurate modulation and tight shutoff across the ANSI Class 250 rated valve bodies, preventing hunting and improving overall loop stability in air handling units and heat exchangers.

• Specifically calibrated for 1-1/2" to 2" valve bodies with a standard 3/4-inch stroke.
• Compatible with V-3000-8001 and V-3000-8003 pneumatic valve actuators.
• Provides a consistent 3 to 6 PSI compression range for reliable spring-return safety functions.
• Includes all necessary components for field retrofit or routine pneumatic valve maintenance.
• Maintains the 25:1 rangeability of Johnson Controls VG7000 bronze valves.

Does this kit work with the smaller 1/2" VG7000 valves?
No, the VG7000-1007 is sized specifically for the larger 1-1/2" and 2" bodies with the 19mm/0.75-inch stroke. Smaller valves typically require the VG7000-1001 or VG7000-1003 series kits.

Can I use this spring kit for steam applications?
Yes, when used with the appropriate VG7000 stainless steel trim valves, this kit is suitable for modulating saturated steam up to 100 psig.

Is this compatible with the V-3801 actuator?
No, this kit is engineered for the V-3000 series. The V-3801 actuator requires a different mounting kit and bonnet adapter (typically the VG7000-1010).
