What is a chip-type stainless steel valve?

A chip-type stainless steel valve is a type of valve composed of multiple valve bodies connected by bolts. It is primarily made of stainless steel (such as 304 or 316L), offering corrosion resistance and excellent sealing, making it particularly suitable for applications requiring frequent opening and closing or demanding high media cleanliness. It mainly comes in three structures: one-piece, two-piece, and three-piece, each with its own characteristics:

Structure and Types:

One-piece: A single valve body with a plug securing the ball. The simplest structure and easy maintenance, but it typically features a reduced bore design, with a flow port diameter smaller than the threaded diameter.

Two-piece: Two valve bodies are bolted together, clamping the ball. Maintenance is more complex than the one-piece type, but it is suitable for both normal and high-pressure environments.

Three-piece: An additional valve body in the middle, clamped on both sides by necked flanges. The most robust structure, suitable for ultra-high-pressure environments, and the easiest to disassemble and maintain.

Working Principle:

The system controls the flow of media by rotating a ball. A 90° rotation fully opens or closes the system. It features low fluid resistance, fast switching, and supports manual, pneumatic, or electric operation.

Main Features:

Corrosion Resistance: Made of stainless steel (304/316L), it is corrosion-resistant and suitable for chemical, food, and pharmaceutical industries.

Reliable Sealing: PTFE or other plastic sealing surfaces isolate the ball from the media during opening and closing, providing high pressure and high temperature resistance (-40℃ to 350℃).

Low Flow Resistance: The channel is unobstructed when fully open, resulting in energy efficiency.

Compact Structure: Small size, light weight, and flexible installation.
