SS3A Series 316 Stainless Steel 3/2 Way Air Control Valves

Features & Key Specifications

Features & Key Specifications of Our SS3A Series:

Premium 316 Stainless Steel Body:
The valve body is machined from solid SS316 stainless steel, offering maximum durability and resistance to corrosive chemicals, cleaning agents, and saline environments.

Extreme Temperature Performance (-30°C to 130°C):
Designed to operate flawlessly in a vast temperature range, this high temperature air valve is ideal for use in cold storage, near industrial ovens, or in hot processing lines.

Safe, Non-Electrical Air Actuation:
As a non-electrical 3-way valve, it provides a secure control method in areas where electrical components are not permitted or desired.

Comprehensive Range of Port Sizes:
This series is highly versatile, available in a full spectrum of port sizes including M5, 1/8", 1/4", 3/8", and 1/2" to meet any flow requirement.

Optimized for Single-Acting Cylinders:
The 3/2 way, normally closed (NC) function is the industry standard for controlling single-acting, spring-return pneumatic cylinders.

Application Fields

Critical for Safe Control in Harsh Environments:

Food & Beverage Processing: Controlling single-acting clamps or diverters in both refrigerated and high-temperature (e.g., steam cleaning, hot-fill) areas.

Pharmaceutical Manufacturing: Used in cleanrooms for controlling small actuators where non-sparking components and temperature resistance are essential.

Chemical Plants: A durable, corrosion-resistant pilot valve for larger chemical process valves, even in fluctuating ambient temperatures.

Industrial Ovens & Furnaces: Controlling pneumatic components located in high-temperature zones.

Marine & Offshore: Safe and reliable control in saltwater environments with exposure to extreme weather.

Technical & Selection Guide

When is the SS3A the Right Choice?

The SS3A is a highly specialized valve. Select it when your application meets these criteria:

You need to control a SINGLE-ACTING cylinder. (This requires a 3-way valve function).

The environment is CORROSIVE, HYGIENIC, or has EXTREME TEMPERATURES. (This requires 316 stainless steel and a high-temp design).

The area requires NON-ELECTRICAL control. (This requires an air pilot valve).

If your application meets these conditions, the SS3A is the perfect, purpose-built solution.

FAQ

Frequently Asked questions

Q: What is the difference between an SS3A and an SS4A valve?
A: The function. The SS3A is a 3-way valve designed for single-acting cylinders. The SS4A is a 5-way valve designed for double-acting cylinders. Both are high-performance stainless steel air pilot valves.

Q: Can this valve really be used at 130°C?
A: Yes. The valve is constructed with materials, including seals, that are rated to perform continuously at an operating temperature of 130°C (266°F), making it ideal for high-heat applications.

Q: Why would I use this instead of a stainless steel solenoid valve (SS3V)?
A: You would choose this SS3A air pilot valve over an SS3V solenoid valve specifically for safety reasons in certain environments, or for building a simple, purely pneumatic control system without any wiring.
