Product Description

Overview

The Leybold Secuvac Vacuum Safety Valve DN 100 ISO-K is a protective valve designed for specific vacuum systems. Below is a detailed overview:

Basic Information

Part Number: 215225

Nominal Size: DN 100 ISO-K

Actuation: Solenoid-driven, pilot valve 24V DC

Features & Applications

Designed specifically for rotary vacuum pumps without a built-in anti-suckback valve. It prevents accidental venting of the vacuum system through the foreline pump during a power failure, ensuring the vacuum system remains sealed and in a vacuum state until the foreline pump restarts and evacuates the gas from the connected pipelines.

It can also be used as a vent valve for vacuum systems, meeting the needs of different vacuum system operating conditions.

Material and Seals

The valve body is typically made of aluminum, which is lightweight and corrosion-resistant. Equipped with FPM (FKM) gaskets, this material is highly resistant to hydraulic fluids, chemicals, and many organic compounds, providing reliable sealing performance and ensuring an overall valve leakage rate of less than 10⁻⁹ mbar·L/s.

Operating Specifications

Pressure Range: Wide operating pressure range, from as low as 10⁻⁹ mbar (7.7 × 10⁻¹⁰ Torr) to as high as 2100 mbar (1575 Torr, 30 psi), meeting the pressure requirements of various vacuum systems.

Temperature Range: Operating temperature range is -20°C to +210°C, ensuring stable operation in a wide range of temperature environments.

Structural Advantages

The compact design and lightweight design take up little space, making it easy to install and maintain.

A clear position indicator visually displays the valve's open or closed status. It is fully operational within the entire specified pressure range and has undergone a helium leak test to ensure that the valve body and valve seat leak rate is less than 10⁻⁹ mbar·L/s, with excellent sealing.

Frequently Asked Questions (FAQ)

What is the primary function of the Leybold Secuvac DN 100 ISO-K valve?

It is designed to protect vacuum systems connected to rotary vacuum pumps without built-in anti-suckback valves. It prevents accidental venting during power failures, keeping the vacuum system sealed. It can also serve as a system vent valve.

What materials are used in the construction of this safety valve?

The valve body is constructed from lightweight, corrosion-resistant aluminum, and it uses FPM (FKM) gaskets, which offer exceptional chemical and thermal resistance for optimal sealing.

What is the operating pressure and temperature range of this valve?

The valve operates across a broad pressure range from 10⁻⁹ mbar (7.7 × 10⁻¹⁰ Torr) up to 2100 mbar (1575 Torr, 30 psi), and handles temperatures from -20°C to +210°C.

What is the actuation voltage requirement for the pilot valve?

The pilot valve is solenoid-driven and requires a control voltage of 24 V DC.

How is the sealing capability verified, and what is the leak rate?

Each valve undergoes a rigorous helium leak test. The verified leak rate for both the valve body and the seat is less than 10⁻⁹ mbar·L/s.
