Home > First Stage Pressure Regulator (Primary Gas Cylinder Regulator) | High Pressure Gas Control Valve
The First Stage Pressure Regulator (also known as Primary Pressure Regulator) is designed to reduce high-pressure gas from cylinders to a stable intermediate pressure for downstream systems. It ensures safe operation, protects equipment, and provides consistent gas flow in industrial and laboratory environments.

A: The regulator body is made of high-quality brass, providing excellent strength, corrosion resistance, and durability. Precision-machined internal components and premium sealing elements ensure reliable pressure control and long service life.
A: Yes. The regulator is compatible with CO₂ cylinders and compressed air systems. Available inlet thread options include W21.8, G5/8, CGA320, M22, and G3/4, making it suitable for various regional gas cylinder standards.
A: The regulator is rated for a maximum inlet pressure of 3000 PSI and features an adjustable outlet pressure range of 0–60 PSI. The pressure gauge provides an accuracy of ±2 PSI for precise pressure adjustment and monitoring.
A: Regular maintenance includes inspecting all threaded connections, valves, and seals for leaks or wear. Keep the regulator clean and dry, periodically check the pressure gauge for proper operation, and replace damaged O-rings when necessary to maintain optimal performance and safety.
