Pneumatic Pressure Switches: Reliable Pressure Monitoring for Industrial Automation
Pneumatic pressure switches are versatile pressure control valves designed to monitor and respond to air pressure changes in pipelines, vessels, and process equipment. With adjustable setpoints and electrical outputs, they provide a cost-effective solution for detecting pressures and initiating control actions or alarms. In this post, we’ll provide an overview of how pneumatic pressure switches…
Read MorePneumatic Valve Actuators for Efficient Automation
Pneumatic Valve Actuators for Efficient Automation Pneumatic valve actuators are critical for ensuring smooth and efficient operation in industrial valve automation. These devices use compressed air to actuate and generate linear or rotary motion, enabling precise control over valve positioning and activation. Gate valves, globe valves, ball valves, and butterfly valves benefit from actuators that…
Read MorePressure Relief Valve Testing Procedures: Best Practices for Pneumatic Systems
(Updated 20 October 2025.) Pressure relief valves protect pneumatic systems from catastrophic overpressurisation that can destroy equipment and endanger workers. Yet many facilities still treat pressure relief valve testing procedures as an afterthought, waiting until an audit forces their hand. Here’s what you need to know about testing pressure relief valves in pneumatic control systems,…
Read MoreHow to Specify Pneumatic Valves and Cylinders
Pneumatic cylinders or pneumatic valves are offered with different industry standards. Within these standards, pneumatic cylinders come in a wide variety of shapes, sizes, and types, and embrace a wide range of optional features. Of course, each pneumatic type and configuration has a place in today’s motion-centric automation environment. But sometimes, a special job falls…
Read MorePressure Control Valve: All About Air Pressure Sensors
For optimal HVAC systems and the proper performance of such systems, accurate air pressure measurement is important. Air pressure sensors are used to measure very low to high pressures in air and refrigerants. Pressure control valve sensors provide precise measurement of air pressure, any differential pressure, and high accuracy volumetric flow needing reliable monitoring. Air…
Read MoreTypes of Pneumatic Valves: The Pneumatic Gripper
Pneumatic grippers are pick-and-place machines that use compressed air to operate gripper jaws that are also called gripping fingers. These fingers, almost similar in design to human fingers, help in holding, grasping, and releasing work or load items. Commonly, grippers have two fingers that can be parallel or angular, or three fingers with single or…
Read MoreUnderstanding Air Rams Shut Off Systems or Shut Off Valves
Shut off valves are also called air rams shut off systems, lockout valves, cut off valves, shutdown valves, emergency valves, ball valves, and exhausting valves. Shut off valves are designed to safely manage compressed air used for pneumatic applications. They are also used to block compressed air in any industrial automation process during emergencies or…
Read MoreThe Right Pressure Control Valve Matters: Poppet Valve or Spool Valve?
The most common designs for a pressure control valve are the spool and poppet. When you need to choose between 3- and 4-way valves for pneumatic or pressure control circuits, you need to take the internal design of a poppet valve or spool valve into consideration. Using either a poppet valve or spool valve will…
Read MoreThe Flow Control Valve Called a Spool Valve
A spool valve is a type of flow control valve that is part of a hydraulic or pneumatic system that controls or regulates the flow of fluid or compressed air in a system. The valve is made of cylindrical spools that slide or rotate which allows or stops the flow of liquid. The spool valve…
Read MoreMack Pneumatic Valves: Proudly Australian Made
Mack Valves are made in Australia. Its pneumatic valves and other valves and cylinder systems are widely known internationally for their reliability, robust designs, and longevity. Master Mac 2000 is proud to be one of its distributors, especially in Queensland and Northern New South Wales. And as the leading Australian valve manufacturer, Mack Valves is…
Read MorePressure Control Valve: All About The Check Valve
How does a check valve work? A check valve is a type of pressure control valve that allows only a single direction for the flow of fluids. There are only two ports: an inlet port and an output port. Since the media is only allowed to flow in one direction, check valves’ main purpose is…
Read MoreAir Rams: What are Shuttle Valves?
Oil unloader This is a specialised shuttle valve that is mounted on the front of the pump assembly housing. This valve in an oil unloader allows air pressure to flow to the power unit. During a power exhaust stroke, when airflow is reversed and the shuttle valve is lifted from its seat, any oil inside…
