Valves & Valve Assemblies

PPI can satisfy your valve needs, whether it is replacement of a single ball valve or a complete stream distributor assembly with diverter valve, solenoid valve, actuator, valve position indicator and lubricator.

We offer a wide range of replacement valves that are compatible with equipment from leading polyurethane machinery manufacturers, including diverter valves (also known as stream distributors, DN-16 and DN-25 valves), ball valves, butterfly valves, and pressure relief valves.

We can supply the valves individually or as an assembly, with all necessary components for automatic operation and lubrication. Our process experts can help you select the correct type, size and configuration for your system and application.

Valve Actuators

We supply double acting and spring return actuators to automate the operation of diverter, butterfly, plug or ball valves and dampers.

Solenoid valves and a variety of actuator types and sizes are available, in torque ranges from 25 in-lb to 58,000 in-lb, with 90 to 100-degree travel, and clockwise or counterclockwise adjustment for open and closed positions.

Contact us for details and pricing.

PPI offers high pressure filters and replacement elements to remove particles from the process chemicals before they reach the mix head and restrict flow through the orifices.

We stock European MP Filtri elements and Viking strainers, as well as filter elements and strainers to protect Rexroth and Rotary Power (RHL) metering pumps.

Flow Meters

We offer a wide range of flow meters that precisely measure the volumetric output of chemical metering pumps.

The fluid rotates the meter’s internal gears and a non-contact sensor sends a PNP or NPN pulse output that corresponds to a precise volume. The impulse can be transmitted to a PLC, integral LCD flow display or any other electronic readout.

Our process experts can help you select the correct type and size flow meter for your application.
