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 with it. This blog post will discuss the types of diaphragm check valves and how they work. What […]

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 will not allow air into the process line, a vacuum breaker will. Depending on the […]

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, and other unsafe operating conditions. The following article provides an overview of these valves, including how they work, typical […]

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 pressure. Understanding how pressure switches work, the various types of pressure switches, and the common applications for them is useful […]

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 to ensure that a pressure overload doesn’t break seals or cause an explosion.  Usage/Applications Typically, a spring attached to a […]
