Technical Parameters

Introduction

A cryogenic check valve is a type of valve specifically designed for fluid systems in extremely low-temperature environments. Its primary function is to prevent backflow of liquids or gases in cold chain systems, thereby protecting equipment and maintaining stable system operation.

Features

Unidirectional Flow

The unidirectional valve core structure ensures that fluid flows in only one direction, preventing the backflow of low-temperature liquids.

Low Leakage Risk

High-precision seals and valve stem packing design reduce gas or liquid leakage.

Low-Temperature Durability

Stainless steel and HF valve bodies and seals ensure that the valve maintains corrosion resistance and pressure resistance at -196°C.

Installation Compatibility

The flange and butt-weld end designs of the Cryogenic Check Valve facilitate quick connection to different piping systems.

FAQ

Q: Are you a trading company or a manufacturer?

A: We are a professional manufacturer specializing in valve and actuator products. And we directly trade our products with our clients.

Q: Can you do OEM and ODM?

A: Yes, OEM and ODM are both acceptable. The material, size, and connection can be customized; the basic quantity will be confirmed after we discuss.

Q: Can we use our own logo?

A: Yes, we can print your private logo according to your request.

Q: What are the trade and payment terms?

A: Amount less than $1000, 100% paid before production, more than $1000 can be negotiated!

Q: May I have a new sample made with my design for confirmation?

A: Yes. Sample charge means the setup charge for the production line. For a small quantity, we suggest that straight to production. Large quantity we suggest that sample first, and sample fee can be refund.
