This article describes the processes used in Pulp & Paper manufacturing and how to select valve styles to meet the demands of each application.

Brewery High-Strength Receiving Station & Force Main Project

This article describes how Stevens Point Brewery was part of a public-private project to change how the brewery’s industrial wastewater was pumped to the wastewater treatment facility. Stevens Point Brewery installed DeZURIK Cast Iron Eccentric Plug Valves (PEC), Glass Lined Eccentric Plug Valves and Level Sensor Isolation Valves as part of this project.

Narragansett Bay Commission's Field's Point Integrated Fixed-Film Activated Sludge Systems 

Narragansett Bay Commission was required to upgrade its two wastewater treatment facilities to exceed a permit limit of 5 mg/L total nitrogen. Since starting up, the system has effectively reduced total nitrogen concentrations in the upper bay, exceeding expectations. DeZURIK was proud to supply pneumatically operated AWWA Butterfly Valves as part of this project.

Performance Factors and Installation Procedures for AWWA Butterfly Valves  

This article identifies many performance factors to consider when locating or installing AWWA butterfly valves in a pumping, distribution or plant piping system. These factors include the direction of fluid flow through the valve; the presence of upstream and downstream fluid disturbances; the shaft orientation; the rotational direction of disc closure; the proper swing clearance for the valve disc; the valve’s proximity to liquid or solid chemical injection systems; fluid hammer; and the requirements of installation, start-up and maintenance.

Back To Basics: The Always Reliable Plug Valve

Eccentric Plug Valves have been a proven performer for decades and have developed a reputation as a reliable workhorse in everything from water to chemical service, clear liquids to mining slurries, and many applications in between. This article describes the design, how a plug valve works, proper installation, multi-port valves, actuation and applications.
