Neptune QC-316-50 Injection Quill | 1/2" 316SS 3,000 PSI

Neptune QC-316-50 High-Pressure Injection Quill

The Neptune QC-316-50 is a professional-grade 1/2" injection quill designed for the rapid dispersal of water treatment chemicals into the turbulent flow zones of high-pressure lines. By injecting chemicals into the center of the pipe stream, this quill prevents corrosive wall travel and localized pipe thinning, significantly extending the life of your steam and boiler piping.

Advanced Chemical Compatibility Engineered for reliability, the QC-316-50 features a full 316 Stainless Steel body and an integrated Hastelloy C-276 spring-loaded ball check. This high-spec material combination ensures the check valve remains functional even when exposed to aggressive boiler chemistries and extreme thermal cycling. The use of Hastelloy C for the internal spring provides a superior level of protection against stress-corrosion cracking compared to standard alloy springs.

Technical Specifications:

• Process Connection: 1/2" Male NPT

• Body Material: 316 Stainless Steel

• Spring Material: Hastelloy C (C-276) for superior corrosion resistance

• Maximum Pressure: 3,000 PSI

• Maximum Temperature: 750°F

• Check Valve: Internal ball-check to prevent process backflow

The Water Treatment Resource Advantage: Most standard quills fail at the spring or the check valve seat. By utilizing a Hastelloy C spring, the QC-316-50 maintains its tension and sealing capability far longer than standard stainless springs when exposed to high-pressure chemical feeds. This unit is built specifically for the demands of industrial mechanical rooms and high-output boiler systems.
