SSA Series Stainless Steel In-line Speed Controllers

Features & Key Specifications

Features & Key Specifications of Our S-SA Series:

In-Line Tube-to-Tube Control:

Designed to be placed anywhere along a pneumatic tube run, this fitting provides speed control flexibility that port-mounted controllers cannot offer.

Precise Needle Valve Adjustment:

The knurled adjustment knob allows for fine-tuning of the flow rate. This fitting typically provides meter-out or meter-in control by restricting flow in one direction while allowing free flow in the other.

Premium Stainless Steel Construction:

Available in both 304 and 316 stainless steel, these fittings offer exceptional resistance to corrosion, chemicals, and high temperatures.

Comprehensive Size Options:

We stock a full range of sizes to fit any system.

Tube OD (Metric): 4mm, 6mm, 8mm, 10mm, 12mm

Tube OD (Inch): 5/32", 1/4", 5/16", 3/8", 1/2"

Food-Grade & Oil-Free Design:

Manufactured to be oil-free and compliant with the Food Hygiene Law, our food grade speed controllers are safe for use in sanitary applications.

Application Fields

Precise Speed Control Anywhere in Your Circuit:

Remote Speed Adjustment: Placing the speed controller in a location that is easier for operators to access than a direct cylinder port.

Controlling Cylinder Speed: The primary application is to provide smooth, controlled extension or retraction of a pneumatic cylinder.

Food & Beverage Machinery: A hygienic stainless steel flow control valve for processing and packaging lines.

Chemical & Process Lines: A durable, corrosion-resistant fitting for controlling actuator speed in harsh environments.

Technical & Selection Guide

In-Line (S-SA) vs. Port-Mounted (S-SC) Speed Controllers

Choose this In-line (S-SA) Speed Controller if:

The cylinder port is inaccessible.

You want to place the adjustment knob on a control panel for operator convenience.

You need to control flow in the middle of a long tube run.

Choose a Port-Mounted (S-SC) Speed Controller if:

You want the most direct and responsive control of the cylinder's speed.

The cylinder port is easily accessible.

For the smoothest control, it is almost always recommended to use a speed controller in a "meter-out" configuration (controlling the air exhausting from the cylinder).

FAQ

Frequently Asked questions

Q: What is an in-line flow control valve?

A: It is a speed controller designed to connect a tube on its inlet and a tube on its outlet, allowing it to be installed anywhere "in the line" of a pneumatic circuit.

Q: Does this fitting control flow in both directions?

A: Typically, a pneumatic speed controller has a built-in check valve. This means it provides adjustable flow restriction in one direction (for control) and allows free, unrestricted flow in the opposite direction.

Q: Can I use this fitting for steam?

A: No, this fitting is not rated for the high temperatures of steam. The standard seals are designed for a maximum temperature of 60°C. For steam-compatible fittings, please see our other stainless steel series with FKM seals.
