The man behind MPI's well-known Waterman brand was W.A. Waterman, who was born in 1875 and began manufacturing water control products in Exeter, California in 1911. This is his story.
This white paper explains the basic components of extended bonnets, the applications in which they are used, and the many considerations that go into determining the size and other design features for each individual project.
This white paper provides practical selection guidance to help engineers, owners, and project stakeholders consistently choose the right Waterman water control gate for each application – in order to drive performance and avoid issues like leakage, difficult operation, frequent maintenance, and avoidable costs.
This white paper discusses the three primary elastomers used in AWWA valves in the waterworks industry – EPDM (Ethylene Propylene Diene Monomer), NBR (Buna-N®), and FKM (Fluorocarbon, Viton®) – including the key properties and primary uses of each.
This third edition in our series of glossaries covers a vast array of valve types, as well as a number of key industry standards.
MPI is proud to introduce the new AWWA C518 Double Disc Swing Check Valve, which is designed to provide a cost-effective solution for clean water applications. This reliable new valve is also NSF 61 and NSF 372 certified, making it an ideal choice for drinking water applications.
Part 2 of our valve terminology glossary covers a broad range of industry terms related to actuators and closure controls.
MPI is proud to introduce the Waterman F-55D Heavy-Duty Flap Gate, designed and constructed for long life in critical and high head water control applications.
This white paper covers the basics of Eccentric Plug Valves and focuses specifically on the many factors that determine plug valve orientation.
The first in a series of glossaries developed by MPI, this comprehensive list of industry terms and definitions covers a broad range of general valve terminology.
The Rotating Disc Gate Valve is a staple within the waterworks industry. Its metal seated design, conforming to AWWA C500, makes it ideal for both clean water and wastewater applications. Get the facts on this popular and critical valve in our new white paper.
Swing check valves are probably the most misunderstood valve in the municipal water works industry. Learn the basics of swing check valve design, the pros and cons of each type of closure device, and much more in this informative white paper.
The new High-Performance Butterfly Valve is the latest addition to MPI’s extensive valve lineup, and was designed to deliver exceptional performance, superior sealing capabilities and long life in extreme operating environments
The new Waterman S-6000 Heavy-Duty Sluice/Slide Gates are designed and constructed for long life in critical applications such as dams and rivers, tidal environments, wastewater treatment plants, and any critical operation where the ultimate in reliable, long-lasting performance is essential.
