SS3M Series 316 Stainless Steel 3/2 Way NAMUR Solenoid Valves

Features & Key Specifications

Features & Key Specifications of Our SS3M Series:

Premium 316 Stainless Steel Construction:
The valve body and all wetted parts are manufactured from SS316 stainless steel, making it ideal for hygienic applications and use with corrosive media.

Optimized for Single-Acting Actuators:
The dedicated 3/2 way, normally closed (NC) function is purpose-built to pressurize and vent a spring-return actuator, making it the correct choice for fail-safe valve automation.

Extreme Temperature Performance (-30°C to 130°C):
Engineered to perform flawlessly from deep-freeze to high-heat processes, this high temperature NAMUR valve is exceptionally versatile for any thermal environment.

High-Protection IP65 Coils:
Valves are fitted with Class F insulated coils, allowing them to operate safely at the maximum 130°C temperature. The entire coil assembly is rated to IP65, providing complete protection against dust and water jets.

Direct NAMUR Mounting Interface:
Fully compliant with the VDI/VDE 3845 (NAMUR) standard, this valve bolts directly onto the actuator, ensuring a secure, leak-free connection and simplifying installation.

Application Fields

The Specialist Valve for Fail-Safe Actuation:

Food & Beverage Industry: Controlling spring-return hygienic ball or butterfly valves for fail-safe shut-off.

Chemical Processing: Automating fail-safe process valves in corrosive atmospheres.

Water Treatment: A durable solution for spring-return automated valves exposed to water treatment chemicals.

Pharmaceutical & Biotech: Used in high-purity systems where fail-safe operation and hygienic design are critical.

Industrial Safety Systems: Actuating spring-return dampers or valves in emergency shutdown (ESD) air circuits.

Technical & Selection Guide

Why Choose a 3-Way (SS3M) vs. a 5-Way (SS4M) NAMUR Valve?

This is the most critical selection choice, and it depends entirely on your actuator:

Choose this 3-Way (SS3M) Valve for a SINGLE-ACTING (Spring-Return) Actuator. This type of actuator uses air pressure for one direction (e.g., open) and a large spring to return to its "fail" position (e.g., closed). The 3-way valve is designed to supply air for the power stroke and exhaust it for the spring stroke.

Choose a 5-Way (SS4M) Valve for a DOUBLE-ACTING Actuator. This actuator requires air pressure to both open AND close the valve.

FAQ

Frequently Asked questions

Q: Can I use a 5-way valve on a single-acting actuator?
A: While it's possible by plugging one port, it is not the correct or most efficient method. Using a dedicated 3/2 way NAMUR valve like the SS3M is the proper engineering choice for a single-acting actuator.

Q: Is this valve suitable for a "fail-close" ball valve application?
A: Yes, perfectly. If your ball valve is connected to a single-acting, spring-return-to-close actuator, this SS3M valve is the exact component you need to control it.

Q: Can it handle high-heat, washdown environments?
A: Absolutely. With its 316 stainless steel body, IP65 rating, and 130°C temperature limit, it is designed specifically for these challenging conditions.
