Description
Overview
The Type 7500V Vacuum Regulator is designed to control pressure in high-flow pneumatic systems operating both above and below atmospheric pressure. A single regulator can control pressures ranging from vacuum up to 150 psig, providing a versatile solution for applications requiring vacuum regulation, positive pressure control, or operation across both pressure regions.
A fixed negative 15 psig bias spring enables vacuum outputs up to 29″ Hg, while an adjustable opposing range spring controls positive pressure outputs up to 150 psig. An aspirator minimizes output pressure droop, and an isolated output pressure control chamber helps eliminate vibration during high-flow conditions.
The Type 7500V combines flow capacity up to 250 scfm with sensitivity to output pressure deviations within 1 inch water column. Available with 1/4″, 1/2″, or 3/4″ NPT porting and three output pressure ranges, it provides flexible pressure and vacuum control for demanding industrial pneumatic systems.

How to Select the Right Configuration
Selecting the correct Type 7500V configuration depends on the required output pressure range, connection size, installation environment, adjustment requirements, and desired accessories.
- Select the Vacuum to 15 psig range for systems requiring vacuum control with low positive-pressure capability
- Select the Vacuum to 30 psig range for applications requiring vacuum control with moderate positive-pressure capability
- Select the Vacuum to 150 psig range for applications requiring the widest available positive-pressure operating range
- Select 1/4″ NPT porting for smaller pneumatic connections
- Select 1/2″ or 3/4″ NPT porting for installations requiring larger piping connections
- Select the Stainless Steel Knob Stem option when increased corrosion resistance is required at the adjustment mechanism
- Select the Stainless Steel Adjust Screw option when maximum corrosion resistance is required for the pressure adjustment screw
- Select the Tamper-Proof Cover option when casual or unauthorized adjustment of the output pressure should be prevented
- Select the ATEX option when ATEX 2014/34/EU compliance is required
- Choose pipe, panel, or bracket mounting based on installation requirements

Applications
The Type 7500V is designed for high-flow pneumatic systems requiring controlled vacuum, positive pressure, or both operating conditions from a single regulator.
- Vacuum chamber control
- Chamber evacuation
- Positive-pressure chamber purging
- Vacuum pump systems
- Pressure and vacuum testing systems
- Industrial process control
- Pneumatic automation systems
- Packaging equipment
- Material handling systems
- Vacuum handling equipment
- Process vessels and chambers
- Systems transitioning between vacuum and positive pressure
- High-flow vacuum regulation
- High-flow positive pressure regulation
The typical installation diagrams on page 2 of the specification sheet show two operating arrangements. The first illustrates chamber evacuation below atmospheric pressure using a vacuum pump, while the second illustrates chamber purging with positive pressure. These configurations demonstrate the Type 7500V’s ability to regulate both vacuum and positive pressure in a single system.
Principle of Operation
The Type 7500V uses opposing spring forces to regulate output pressure across vacuum and positive-pressure conditions. A fixed negative 15 psig bias spring establishes the force required for vacuum regulation, allowing the regulator to maintain vacuum outputs up to 29″ Hg. An adjustable opposing range spring provides control of positive output pressure up to the selected range.
When system pressure deviates from the desired setting, the regulator responds by controlling the appropriate pressure or vacuum flow path. The aspirator helps compensate for pressure droop as flow changes, while the isolated output pressure control chamber prevents flow-induced vibration from interfering with regulation.
The cutaway diagram on page 2 identifies the regulator’s atmosphere or positive pressure supply, regulated vacuum, vacuum supply, and atmosphere pressure paths. Together with the two typical installation diagrams, it illustrates how the Type 7500V can be configured for both chamber evacuation and positive-pressure purge applications.
