Superior Valve Solutions for the Water Treatment Industry

DeZURIK has a Full Complement of Valve Products for the Water Treatment Market

Search no further than DeZURIK for the most trusted and reliable isolation and control valves for your water treatment facility. Throughout our 250 years of combined history, DeZURIK, APCO, HILTON and Willamette brand valves have been recognized worldwide manufacturing products that provide superior performance and value in a wide range of applications. We specialize in collaborating with our customers to engineer valves that offer superior performance at the lowest cost of ownership, including the following valve styles:.

Innovative Valve Products for Water Treatment Facilities

Plug Valves

Matt DeZURIK developed the eccentric plug valve in 1928. Continued design enhancements have advanced valve reliability and application capabilities in clean, dirty, viscous, and corrosive liquids, abrasive and fibrous slurries, sludge, and clean and dirty corrosive gases. Eccentric Plug valves are ideal for both on-off isolation and control services. DeZURIK also manufactures 3-way and 4-way plug valves that can accommodate various flow control combinations for mixing or diverting applications.

Butterfly Valves

DeZURIK’s AWWA C504 butterfly valves are used for isolation of clean water and gases. These valves are designed to provide years of trouble-free service in applications throughout water treatment plants. AWWA butterfly valves range in size from 3-144” with pressure ratings to 250 psi.

Check Valves

DeZURIK manufactures a variety of check valve designs and types including swing, rubber flapper, silent, slanting/angle/tilting disc, and vertical check.  All check valves are designed to prevent reverse flow, but engineered with specific performance characteristics to accommodate an endless potential of application and service conditions. From the complex SmartCHECK pump control valve to the simplistic rubber flapper check valve, DeZURIK manufactures each valve in adherence to the highest quality design, manufacturing and testing standards.

Air Valves

DeZURIK manufactures an array of air valves. There are two purposes for air valves. Air Release Valves remove entrained air from a piping system to improve operation by reducing damaging water hammer and also by increasing pumping efficiency. Air Vacuum Valves allow air into the system during shut down procedures to prevent pipe damage from vacuum scenarios. The various designs of DeZURIK’s air valves accommodate clean liquids and gasses as well as dirty liquids containing solids in sewage applications.

Control Valves

DeZURIK’s control valve products include V-Port Ball, Rotary Control and High Performance Butterfly valves. When paired with our double-acting or spring-return actuators and high accuracy positioners, DeZURIK’s control valve package can help improve your facility’s overall operation, efficiency, and profitability. Our control valves are suitable for clean, dirty, viscous, and corrosive liquids and gases.

Ball and Cone Valves

Utilizing unique link and lever torque units, our ball and cone valves allow the controlled opening and closing of waterway valves with less head loss than other types of valves. Perfect for pump stop/start and check services, our ball and cone valves function with electric, hydraulic, pneumatic, and manual handwheel operation. Available in sizes 6-60” and pressure ratings of 125, 150, and 300 psi service.

Surge Relief Angle Valves

DeZURIK’s APCO surge release angle valve is designed to prevent damage to the pump system caused by a pressure surge. The Surge Relief Angle valve is an elbow-body style valve with disc that is held normally closed by a spring assembly. The spring assembly is set to open at a specific pressure and discharges media until the surge subsides and the valve slowly reseats itself. Valves are available in sizes ranging from 2-16” with pressure relief ratings up to 200 psi.

Knife Gate Valves

DeZURIK’s long history of proven knife gate valve technology is easily recognized in the bi-directional, resilient seated KGC-BD knife gate valve specifically designed and manufactured for the water industry. The patented perimeter seat design provides bubble-tight, bi-directional isolation in applications including clean, dirty, viscous, and corrosive liquids; sludges; slurries; clean and corrosive gasses. This valve is fully AIS compliant.  

Hydraulic Power Units

As a system-solutions provider, DeZURIK manufactures standard and custom-designed hydraulic power units for in-plant and remote locations. Each hydraulic power unit is designed to operate per application conditions including extreme conditions such as hazardous atmospheres and submergence applications. All units are performance-tested prior to shipment.  


DeZURIK provides complete actuation for all valves we manufacture. Our offering includes rugged manual lever, nut, handwheel and chainwheel operators, gear units, robust double acting rotary and linear units, and spring diaphragm actuators. DeZURIK also partners with all major actuator manufacturers to provide the ideal valve/actuator package for your application.

Valve Accessories

In order to provide a complete valve solution package, DeZURIK offers many optional valve accessories. Pump & Control Valve and Hydraulic Power Unit Interfaces, valve positioners, valve position indication, solenoid valves, and speed controls are just some of the accessories provided by DeZURIK. DeZURIK also offers a wide variety of extensions for remote operation. All accessories are installed and tested as part of the complete valve assembly.
