Description
Overview
The Type 3500 High Pressure Regulator is a dependable first-cut pressure regulator designed to reduce inlet pressures as high as 6000 psig (413 bar) down to usable working pressures ranging from 0 to 225 psig. Constructed from durable brass materials, the Type 3500 provides an economical solution for high-pressure gas regulation in industrial, OEM, and process control applications.
Available in five spring ranges, the Type 3500 delivers stable pressure control while accommodating a wide variety of operating requirements. Its non-relieving design, replaceable valve seat, and multiple outlet ports provide installation flexibility and long service life in demanding environments.
The Type 3500 is commonly used as a pilot supply regulator where high-pressure operating valves require stable gas pressure for pilot operation. Its compact design and high-pressure capability make it ideal for industrial gas systems and process control applications utilizing non-corrosive gases.

How to Select the Right Configuration
Selecting the correct Type 3500 configuration depends on required outlet pressure, gas type, and application requirements.
- Select the 0-30 psig range for low-pressure pilot systems
- Select the 0-60 psig range for general instrumentation service
- Select the 0-125 psig range for medium-pressure control systems
- Select the 0-150 psig range for higher pressure pilot applications
- Select the 0-225 psig range when maximum outlet pressure capability is required
- Choose socket head adjustment for tamper-resistant installations
- Choose tee handle adjustment for convenient field adjustment
- Use the Type 3500 for non-corrosive gas applications
- Take advantage of the three outlet ports for simplified system plumbing
- Consider the replaceable seat design to reduce maintenance costs over the regulator lifecycle
