To withstand aggressive and corrosive solutions in miniature chemical-processing pipelines, these tiny valves have a chemical-resistant fluoroelastomer seal and a corrosion-resistant 303 stainless steel body. They are standard port, so they slightly restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Also known as diaphragm valves, these have a PTFE body and seals that stand up to harsh acidic solutions. The diaphragm can handle dirty liquid, slurries, and abrasive media without damage. All valves operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation.
All have a single-acting actuator that only requires air pressure to open the valve; they automatically spring closed when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valves are normally closed unless actuated.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Calibration Columns
Calibrate the flow rate of metering pumps. A graduated scale with zero at the top lets you easily see how much fluid is lost over the course of a one-minute test. This will tell you your pump’s flow rate. Periodic testing helps alert you to issues in your system, such as worn or dirty valves. Checking the flow rate after performing maintenance ensures your pump is working properly.
Install the column between your reservoir and pump. They require shutoff access to your reservoir and an on/off valve (not included) at the point where they connect to your system. To start the test, open the on/off valve as the system is running to fill the column with fluid up to the zero mark. Shut off the valve and wait one minute before observing the liquid level in the column. After you've taken the reading, close the on/off valve to the column and reopen access to the reservoir.
Borosilicate glass calibration columns and their fittings stand up to sulfuric acid, hydrochloric acid, and other corrosive chemicals.
