Back Pressure Valves

Ensure that certain types of pumps deliver consistent flows or allows for high accuracy and stable operation.

Pressure Relief Valves

Protect from an upset condition including pressure spike, over pressurization, and closed valve.

Calibration Columns

Designed to enhance the performance of chemical feed system by providing a verification of the flow rate of the chemical feed pump. Offering a wide range in sizes and material options that work in many different applications.

Injection Valves

Designed to ensure that chemical feed systems inject into the center of a process stream for better mixing and to prevent corrosion along the process pipe.

Gauge & Instrument Guards

Designed to enhance the performance of chemical feed systems.

Corporation Stops

Designed to ensure that chemical feed systems inject into the center of a process stream for better mixing and to prevent corrosion along the process pipe. retractable and offer a ball valve to seal the process stream for servicing.

Pulsation Dampeners

Designed to enhance the performance of the chemical feed systems by reducing harmful shock waves and delivering continuous chemical dosage at the injection point.

Y-Strainers

Designed to enhance the performance of chemical feed systems, with this addition to the suction side of the chemical feed pump, it prevents debris from entering the pump and clogging the check valves or causing damage to the interior of the pump head.
