Tech Master GPS 421 (GA3500) 5 Port Single Stage Piston Cylinder Regulator
The Tech Master GPS 420/421, is a robust single-stage piston cylinder regulator designed for primary pressure gas control of non-corrosive or toxic, technical grade inert gases up to grade 4.5 purity (99.995%).
It is particularly suitable for applications where slight pressure variation from decreasing cylinder pressure is acceptable.
The regulator’s construction in brass ensures durability, making it ideal for various process control applications, high-pressure vessel testing, and purging, as well as in industrial, laboratory, and research settings.
- All Brass Construction: Ensures durability and resistance to daily wear and tear.
- Five-Port Configuration: Offers versatile connection options for different system needs.
- Encapsulated Valve and Seat Design: Minimizes contamination risks, essential for maintaining gas purity.
- Front and Rear Panel Mounting Capabilities: Allows for flexible installation in diverse environments.
- Low Wetted Surface Area: Reduces the risk of gas contamination.
- High Pressure Vessel Testing: Ideal for testing scenarios requiring precise pressure control.
- Process Control: Suitable for various industrial control applications.
- Laboratories and Research: Effective in settings where precise regulation of inert gases is necessary.
