SR Series Full 316 Stainless Steel Air Pressure Regulators

The SR Series sets the standard for precise and stable pressure control in the most demanding environments. As a full 316 stainless steel air pressure regulator, every major component is crafted from SS316 for maximum durability. Designed to handle inlet pressures up to 1.6 MPa (16 bar), this corrosion-resistant regulator is engineered to deliver reliable performance in washdown, saline, or chemically aggressive atmospheres. Ideal for the food, pharmaceutical, and chemical industries, the SR series provides the high-precision pressure control necessary for critical applications.

Features & Key Specifications

Features & Key Specifications of Our SR Series:

Full 316 Stainless Steel Construction:

Unlike standard regulators, the SR series features a SS316 body and components, offering unparalleled resistance to corrosion and physical damage.

High-Pressure Operation (up to 1.6 MPa):

This regulator is built to handle high-pressure main lines, safely accepting an inlet pressure of up to 1.6 MPa (16 bar / 232 PSI) while providing stable, adjustable output pressure.

Precise & Stable Pressure Regulation:

The high-resolution control mechanism allows for precise adjustment of the downstream pressure and maintains a stable output, even with fluctuations in the inlet pressure.

High Flow Capacity:

Designed for minimal pressure drop, these regulators offer excellent flow rates (up to 7600 L/min) to power even large pneumatic components without starving them of air.

Universal Thread Options (BSPP, BSPT, NPT):

To ensure global compatibility, we offer three thread standards: G (BSPP) for most regions, P (BSPT), and T (NPT) for the North American market.

Designed for Harsh Environments:

The robust construction makes this an ideal washdown air regulator. It is built to withstand the rigors of hygienic cleaning protocols and harsh industrial conditions.


Application Fields

Essential for Precision Control in Critical Industries:

Food & Beverage: Providing clean, stable air pressure for processing and packaging machinery in sanitary environments.

Pharmaceutical & Biotech: A perfect food grade pressure regulator for bioreactors, tablet presses, and cleanroom automation.

Chemical Processing: Reliably regulating air pressure in corrosive atmospheres where standard regulators would quickly fail.

Marine & Offshore: A saltwater-resistant solution for controlling deck machinery and onboard pneumatic systems.

Paint & Finishing: Delivering clean, consistent pressure for high-quality spray finishing applications.


Technical & Selection Guide

Why Choose a Full Stainless Steel Regulator?

Ultimate Corrosion Resistance: If your environment involves moisture, washdowns, salt, or chemicals, a standard aluminum or zinc regulator will corrode. The full 316 stainless steel construction of the SR series is essential for a long, reliable service life.

Hygienic Compliance: For any food grade or pharmaceutical application, stainless steel is the required material to prevent contamination and withstand sanitation processes.

Enhanced Durability: The SS316 construction is inherently stronger and more resistant to physical impact than die-cast alternatives, making it ideal for tough industrial settings.


FAQ

Frequently Asked questions

Q: What is the function of an air regulator?

A: An air pressure regulator takes a higher, often fluctuating, inlet air pressure from a compressor and reduces it to a lower, stable outlet pressure that is required by the pneumatic device.

Q: What is the maximum inlet pressure for this regulator?

A: The SR series is rated for a maximum working inlet pressure of 1.6 MPa (16 bar / 232 PSI).

Q: Can this be used for regulating water or other gases?

A: This regulator is specifically designed and calibrated for use with compressed air. For regulating other media like water, nitrogen, or other gases, please consult with our technical team to ensure a safe and compatible solution.
