How Diaphragm Check Valves Work

Check valves are used in many applications to control the flow of gases or liquids using varying mechanisms. Vacuum systems and small-bore, low-pressure systems often incorporate diaphragm check valves to prevent reverse flow and the risks associated…

What Is Check Valve Cracking Pressure?

Check valves are used in various tubing and pipeline systems to control the flow of liquid or gas. One critical specification of check valves is their cracking pressure, which affects the check valve’s reseal pressure and overall performance.…

How Vacuum Regulators Work

A vacuum regulator controls and stabilizes pressure through the use of inlet and outlet ports that allow higher pressure air into or out of the system as needed. Vacuum breakers and regulators operate under similar principles, but where a regulator…

How Check Valves Work

Check valves—also referred to as non-return, one-way, or clack valves—are valves designed to allow for unidirectional fluid flow. They are employed in a wide range of fluid handling systems as a preventative measure against backflow, overflow,…

How Pressure Switches Work

Pressure switches are important components for controlling the activation and deactivation of pumps in fluid systems when pressure thresholds are reached. They are also used in process control systems for maintaining steady pneumatic or mechanical…

The Basics of Pressure Relief Valves

Pressure relief valves—also known as pressure release valves—open at predefined pressure threshold to release fluid or air until the internal pressure of the system returns to tolerable levels. These valves are essential in many processes…
