SS4M Series 316 Stainless Steel NAMUR Solenoid Valves

Features & Key Specifications

Features & Key Specifications of Our Stainless Steel NAMUR Valves:

Full 316 Stainless Steel Body:
The valve body is machined from solid SS316 stainless steel, providing superior protection against aggressive chemicals, washdown procedures, and harsh industrial atmospheres.

Extreme Temperature Range (-30°C to 130°C):
Built to perform in the toughest conditions, this high temperature NAMUR valve operates reliably in environments from deep cold to extreme heat, making it suitable for a vast range of applications.

High-Performance Industrial Coils:
Valves are fitted with energy-efficient coils featuring Class F insulation, which allows them to withstand the 130°C maximum operating temperature. The entire coil assembly is rated to IP65 for dust and water jet protection.

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

Dedicated 5/2 Way Function:
Designed as a dedicated 5/2 way stainless steel NAMUR valve, it provides the two distinct output paths required for reliable control of standard double-acting pneumatic actuators.

Application Fields

The Standard for Actuator Control in Harsh Environments:

Chemical & Petrochemical Plants: Automating process valves in corrosive atmospheres with fluctuating temperatures.

Food & Beverage Industry: Controlling hygienic butterfly or ball valves on process lines. The washdown NAMUR valve design is essential here.

Pharmaceutical & Biotech: Used in high-purity systems where both cleanliness and temperature resistance are critical.

Water & Wastewater Treatment: A durable solution for automated valves exposed to water treatment chemicals.

Marine & Offshore: The SS316 NAMUR valve is ideal for resisting corrosion from saltwater spray on ships and platforms.

Technical & Selection Guide

Why Choose a Stainless Steel NAMUR Valve?

For Corrosive Environments: If the actuator is located in a washdown area, outdoors, or in a chemically aggressive atmosphere, a standard aluminum NAMUR valve will fail. The SS4M's 316 stainless steel body is essential for a long service life.

For Hygienic Applications: In food or pharmaceutical processing, all components should meet sanitary standards. A food grade actuator valve system requires a stainless steel NAMUR valve.

For Simplified, Robust Installation: The direct-mount NAMUR design is inherently cleaner and more reliable than using a remote inline valve with tubes and fittings, as it eliminates potential leak points.

FAQ

Frequently Asked questions

Q: What is a NAMUR valve?
A: A NAMUR valve is a solenoid valve designed to be mounted directly onto the side of a pneumatic actuator, following the VDI/VDE 3845 standard. This direct connection simplifies plumbing and improves reliability.

Q: Can this valve be used in hot environments?
A: Yes, absolutely. With its Class F insulated coil and robust construction, this valve is rated for a maximum operating temperature of 130°C (266°F), making it ideal for use near ovens, steam lines, or in hot climates.

Q: What is Class F insulation for a coil?
A: Class F insulation means the coil is designed to operate safely at higher temperatures (up to 155°C) compared to lower classes. This results in a more robust coil that is less likely to burn out, especially in demanding conditions or warm environments.
