Griffco Brass Corporation Stop CSB Series with PVC Nozzle Assembly

Griffco Brass Corporation Stop CSB Series with PVC Nozzle Assembly is an advanced solution for optimizing chemical feed systems in municipal and industrial applications. They ensure precise chemical injection, improved mixing, and corrosion prevention by directing chemicals to the center of the process stream. Featuring an integrated check valve, they prevent backflow and maintain system integrity. Their robust design allows hassle-free quill servicing without shutting down operations, offering durability and easy installation. Built for high performance under up to 150 PSI and 140°F, these stops ensure fluid isolation, positive shut-off, and seamless maintenance, making them an essential upgrade for reliable chemical injection systems.

Griffco Chemical Injectors

Griffco Chemical Injectors are designed to enhance chemical injection in process systems, ensuring optimal mixing and preventing scale build-up and pipeline corrosion. They feature a built-in check valve to prevent backflow, a 4-inch extended quill for deeper chemical feed, and durable machined construction for long-term reliability. Key benefits include cost efficiency, ease of connection with a Viton O-ring and Hastelloy C spring for flexible installation angles, and the option for custom quill lengths up to 24 inches for specific requirements.

Griffco PVC Calibration Cylinders with EZ Clean Removable Top

Griffco PVC Calibration Cylinders with EZ Clean Removable Top provide a reliable, cost-effective solution for optimizing chemical feed systems by allowing real-time flow rate verification. Made from durable Schedule 40 PVC with clear, easy-view tubes, they ensure accurate measurement in both mL and GPH, featuring high-contrast markings for easy readability. Available in various sizes (200–7000 mL), they support maximum flow rates of up to 221.9 USGPH and are designed for simple installation in the suction line of chemical metering pumps. The cylinders include a ventilated top cover with a Viton O-ring for easy cleaning and operate with a maximum pressure of 15 PSI. Measurements can be converted to LPH or GPH using the provided formulas.

Griffco M-Series PVC Pressure Relief Valves

Griffco M-Series PVC Pressure Relief Valves safeguard chemical feed systems from over-pressure damage caused by defective equipment or line blockages, ensuring operator safety and system integrity. Designed for municipal, industrial, agricultural, and pharmaceutical applications, these valves feature a PTFE/EPDM diaphragm held by an internal spring, which opens to divert excess chemicals back to the storage tank when system pressure exceeds the adjustable preset range of 10–150 PSI (factory set at 50 PSI). Reliable and cost-effective, they are easy to install close to pumps and compatible with NPT threaded connections. Available in various sizes, they support flow rates up to 15 USGPM and pressures up to 350 PSI.

FAQs

1. What are back pressure valves used for?

Back pressure valves maintain consistent pressure in metering systems, ensuring accurate dosing and preventing siphoning or overfeeding in low-pressure applications.

2. Why are pressure relief valves important?

Pressure relief valves protect systems from damage by releasing excess pressure, safeguarding equipment and preventing accidents.

3. What is a pulsation dampener, and why is it needed?

A pulsation dampener reduces pressure fluctuations caused by pump strokes, providing a smoother flow and protecting downstream components.

4. What are injection valves, and where are they installed?

Injection valves ensure the correct injection of chemicals into the process line while preventing backflow; they are typically installed at the discharge point.

5. When should a back pressure valve be adjusted?

Adjust back pressure valves when the system's discharge pressure changes to maintain consistent dosing performance.
