PULSAtron J41873 Injection Valve Assembly
PULSAtron J41873 injection valve assembly with PVC body, PTFE seat, ceramic check ball, 1/2-inch OD tubing and 1/2-inch NPT male process connection.
The PULSAtron J41873 is an injection valve and back-pressure check valve assembly designed for compatible PULSAtron chemical metering pump systems. Installed at the end of the discharge tubing, the valve provides a controlled chemical injection point while helping prevent process fluid from flowing backward toward the metering pump.
The J41873 features a PVC body, PTFE valve-seat material, a ceramic check ball, a 1/2-inch OD tubing connection and a 1/2-inch NPT male process connection.

Injection Valve Function
The J41873 is installed at the chemical injection point at the end of the pump discharge tubing. During operation, chemical delivered by the metering pump passes through the valve and enters the process stream.
The internal check-valve mechanism helps maintain one-way chemical flow while restricting process fluid from flowing backward into the chemical feed line.
Back-Pressure Check Valve Operation
The ceramic check ball works together with the PTFE valve seat to provide directional flow control. This helps protect the chemical feed line from reverse flow and supports dependable metering pump operation.
PVC, PTFE and Ceramic Construction
The J41873 combines a PVC valve body with a PTFE/TFE valve seat and ceramic check ball. The valve accepts 1/2-inch OD discharge tubing and connects to the process through a 1/2-inch NPT male connection.

Installation
The J41873 is installed at the end of the pump discharge tubing. The 1/2-inch OD tubing connects to the valve using the coupling connection, while the 1/2-inch NPT male end connects to the compatible process injection point.
Maintenance & Replacement
Inspect the injection valve periodically for chemical deposits, restricted flow, sealing wear or contamination around the ceramic check ball. Proper valve operation helps maintain consistent chemical injection and prevents unwanted reverse flow.
Always verify the complete PULSAtron pump model, wet-end configuration, tubing size and process connection before installing the J41873.
