Johnson Controls VG7000-1008 Spring Kit

The Johnson Controls VG7000-1008 Spring Kit is a professional-grade field mounting solution engineered for precise pneumatic valve actuator calibration. Designed specifically for Johnson Controls V-3000 series actuators, this kit allows technicians to establish a reliable 4-8 PSI spring range on larger valve bodies. It is fully compatible with 1-1/2 inch and 2 inch valve bodies featuring a 3/4 inch stroke (19 mm), ensuring optimal seating force and close-off pressure in demanding HVACR environments.

Constructed for durability in high-cycle applications, the VG7000-1008 facilitates accurate modulation of steam and water flow within commercial HVAC systems. This kit is essential for field retrofits or maintenance where the original spring rate must be adjusted to meet specific system requirements. By utilizing a genuine Johnson Controls replacement part, contractors ensure seamless integration with the actuator?s internal diaphragm and stem assembly, maintaining the ANSI Class 250 pressure rating integrity of the VG7000 series bronze valves. This valve linkage kit provides the necessary mechanical resistance to return the valve to its fail-safe position effectively.

• Precise Actuation: Provides a calibrated 4-8 PSIG range for accurate proportional control.
• Broad Compatibility: Engineered for DN40 (1-1/2") and DN50 (2") valve bodies with a standard 3/4" stroke.
• Heavy-Duty Reliability: Designed to withstand the thermal and mechanical stresses of saturated steam and hot water applications.
• Field Interchangeability: Simplifies the process of adapting V-3000-8001 and V-3000-8012 actuators to various plumbing configurations.

Which actuators are compatible with the VG7000-1008?
This kit is primarily designed for use with Johnson Controls V-3000 pneumatic actuators, specifically models such as the V-3000-8001, V-3000-8003, and V-3000-8011/8012 during field mounting or spring replacement.

Can this kit be used on 1/2" or 1" valves?
No, the VG7000-1008 is specifically sized for 1-1/2" and 2" valves. Smaller valve bodies (1/2" to 1-1/4") require different spring kits, such as the VG7000-1001 or VG7000-1004, to accommodate shorter stroke lengths.

What is the primary function of the 4-8 PSI range?
The 4-8 PSI spring range determines the air pressure required to move the valve stem. It is typically used in applications where specific sequencing or close-off forces are needed to manage system flow against varying line pressures.
