Valfonta Model 260 Steam Reheater Injector

The Resideo DRU Three-Way Rotary Valve is designed to optimise water temperature control in heating and air-conditioning systems. This sophisticated valve is engineered to provide precise mixing control between supply water and return-flow temperatures. Constructed from robust red brass, it ensures durability and reliability, particularly when used with M6061/VMM and M7061/VRM actuators. Its innovative inner housing design features an interchangeable rotary plug, allowing for seamless adaptation to various applications without the need to drain the system. Furthermore, when paired with the distance-adjustable H-Extension, it can function effectively within a diverse range of pre-piped systems. **Key Features:** - Interchangeable rotary plug for versatile use - Durable cast iron housing for long-lasting performance - Chrome-plated plug to enhance longevity - Optimised characteristics for efficient supply water temperature control - Simple and reliable installation of electrical actuators - Available in two housing sizes to accommodate a broad spectrum of flow rates - Streamlined, compact design - Suitable for manifold use with the optional H-Extension - Thermal insulation package included **Product Codes:** DRU25-6.3, DRU25-10, DRU32-10 Optimise your heating and air-conditioning systems with the Resideo DRU Three-Way Rotary Valve – the reliable solution for effective water temperature control.

Four-Port, Brass Barstock, High Flow Pipeline Regulator for High Purity Inert Gas Applications

The CONCOA 483 Series regulator is designed for high flow inert gas applications, including bulk gas distribution, high purity chamber pressurization, and liquefied hydrocarbon analysis. Its internal pressure equalization minimizes delivery pressure variations typical in pipeline systems. Rated to full cylinder pressure, the 483 Series ensures safe operation even in the event of primary pressure control failure.
