SS-ASC Series Stainless Steel Pneumatic Speed Controllers

Features & Key Specifications

Features & Key Specifications of Our SS-ASC Series:

Premium 316 Stainless Steel Construction:
The entire valve body and adjustment knob are made from SS316 stainless steel, delivering maximum durability and resistance to rust, chemicals, and frequent washdowns.

Precise Flow Adjustment for Speed Control:
The knurled adjustment knob allows for fine-tuning of the exhaust air flow from a cylinder, providing smooth and precise control over the actuator's speed.

Extreme Temperature Performance (-30°C to 130°C):
Utilizing high-performance HNBR seals, this high temperature flow control valve operates flawlessly in both freezing conditions and high-heat applications.

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.

Full Range of Port Sizes:
This series covers a wide array of flow requirements with port sizes available from 1/8" up to 1", suitable for both small and large pneumatic cylinders.

In-Line Design for Easy Installation:
These speed controllers are designed to be installed directly in the tubing line or at the cylinder port for simple and effective "meter-out" or "meter-in" control.

Application Fields

Essential for Controlled Motion in Harsh Environments:

Food & Beverage Processing: Controlling the speed of cylinders on packaging, bottling, and conveying equipment in washdown areas.

Pharmaceutical & Medical: Precise speed regulation for actuators in cleanroom automation and medical devices.

Chemical Plants: A durable, corrosion-resistant method for controlling actuator speed in aggressive atmospheres.

Industrial Ovens & Furnaces: Reliable speed control for pneumatic components operating in high-temperature zones.

Marine & Offshore: A saltwater-resistant solution for controlling the speed of pneumatic equipment on ships and platforms.

Technical & Selection Guide

How to Use a Speed Controller

A pneumatic speed controller is a type of flow control valve, typically with an integrated check valve. This allows free flow in one direction and restricted (adjustable) flow in the other.

For "Meter-Out" Control (Most Common): To control the speed of a cylinder, you should restrict the air leaving the cylinder. Install the speed controller on the cylinder port so that it restricts the exhaust air. This creates back pressure and results in much smoother, more stable cylinder motion.

Choosing the Right Thread:

G (BSPP): Straight thread with a seal. Common in Europe and Asia.

T (NPT): Tapered thread. The standard in North America.

P (BSPT): Tapered thread. Also known as Rc thread.

FAQ

Frequently Asked Questions

Q: What is the difference between a speed controller and a simple needle valve?
A: A speed controller (flow control valve) typically restricts flow in only one direction and allows free flow in the reverse direction, thanks to an internal check valve. A needle valve restricts flow equally in both directions. For controlling cylinder speed, a speed controller is the proper device.

Q: Can I use this for liquids like water?
A: While primarily designed for pneumatic (air) service, the 316 stainless steel construction is compatible with water and many other liquids. However, its flow characteristics are optimized for compressible air. Please consult our technical team for liquid applications.

Q: Why choose stainless steel over a standard brass or plastic speed controller?
A: You must choose stainless steel for any food grade, hygienic, or corrosive application. It is also far more durable and resistant to high temperatures and physical damage.
