Flanged Liquid Turbine Flow Meter

The CONCOA 312 Series is a five-port, chrome-plated brass barstock, dual-stage cylinder regulator designed for high-purity inert gas applications. It provides primary pressure control for non-corrosive, high-purity (up to grade 5.5) or liquefied gases. Its two-stage design reduces pressure fluctuations caused by supply cylinder depletion, making it ideal for applications requiring stable delivery pressure. Configurable at the factory, it can serve as a single-station manifold with options such as purge, low-pressure alarm, or multiple inlets.

This spring-operated liquid relief valve features a cartridge-type assembly that can be easily withdrawn from the body without disturbing the spring setting, thus relieving pressure efficiently. This innovative design allows for the cleaning of seating surfaces without the need to reset the valve, making maintenance straightforward and hassle-free. Commonly used with positive displacement pumps for relief or bypass applications, the spring cartridge assembly can also be supplied separately for integration as a pump bypass relief valve. Furthermore, the spindle is equipped with an ‘O’ ring to safeguard the spring, especially in corrosive environments.
