Comprehensive Guide to Pinch Valves

Pinch valves are essential components in various industrial applications, providing a reliable solution for controlling the flow of fluids and gases. These valves utilize a unique mechanism that pinches a flexible tube to open or close the flow, making them ideal for handling slurries, powders, and other media that may clog traditional valves. In this guide, we will explore the technical features, types, and applications of pinch valves, along with insights from leading manufacturers in China.

Technical Features of Pinch Valves

Pinch valves are designed with several key features that enhance their performance and reliability. Below is a comparison table highlighting the technical specifications of pinch valves:

Feature	Description
Body Material	Typically made from lightweight metals or plastic polymers.
Sleeve Material	Commonly uses elastomers like EPDM, NBR, or FDA-approved rubber.
Operating Pressure	Ranges from 3 to 40 Bar, depending on the valve type and size.
Temperature Range	Designed to withstand varying temperatures, depending on the sleeve material.
Flow Control	Provides full bore opening for unobstructed flow, reducing clogging risks.
Maintenance	Low maintenance due to the simple design and self-cleaning properties.
