Manual Actuators
Tek-Sales supplies a wide range of DeZURIK manual actuators engineered for reliable, low-maintenance operation on key valve families such as BHP High Performance Butterfly Valves, BOS-US Resilient Seated Butterfly Valves, BAW AWWA Butterfly Valves, RCV Rotary Control Valves, VPB V-Port Ball Valves, and small Eccentric Plug Valves. Our team helps engineers and operators choose the right manual operator based on torque requirements, environment (including buried/valve vault applications), safety/lockout needs, and access constraints.
DeZURIK MG Manual Gear Actuators
DeZURIK MG Manual Gear Actuators provide smooth, high-torque manual operation for a variety of DeZURIK rotary valves, including BHP, BOS-US, RCV, VPB and ½–3" eccentric plug valves. Built with cast iron housings and robust gearing, MG actuators are ideal where dependable manual control is required without the complexity of powered actuation. Key design elements include:
-
Bronze-supported input shafts for long bearing life and a ductile iron gear sector sized for demanding service.
-
MG actuators are available with handwheel or chainwheel inputs, making them suitable for both floor-level operation and overhead or pit installations.
-
External position indication and adjustable open/close stops allow straightforward setting and verification of travel limits in the field.
MG operators are factory-sealed against moisture and contaminants and filled with high-temperature lubricant for long service intervals. Tek-Sales can assist with torque checks, selection, and integration of MG gear operators into new or retrofit projects.
DeZURIK G-Series Cylinder Actuators
The G-Series Manual Gear Actuator is DeZURIK’s heavy-duty manual operator for larger or higher-torque rotary valves, including PEC/PEF eccentric plug valves, BAW AWWA butterfly valves, BHP high performance butterfly valves, and BOS-US resilient seated butterfly valves. These actuators are designed for applications where consistent torque, precise travel limits, and long service life are critical.
G-Series actuators use a cast iron housing with a rugged ductile iron gear, supported by bronze bearings at both ends of the input shaft to maintain alignment and reduce wear. They are available with handwheel, chainwheel, or 2" square operating nut, allowing flexibility for buried service, vaults, or overhead access. Standard features include:
-
External, easy-to-read position indicator
-
Externally adjustable open and close travel stops
-
Weatherproof, sealed housings to keep out dirt and moisture
-
Factory grease fill suitable for wide temperature ranges
-
Optional lockout capability for safely securing the valve in open, closed, or intermediate positions
G-Series manual gear actuators can also be supplied for buried service, making them a strong choice for critical water and wastewater infrastructure.
Spring Diaphragm Actuators
Tek-Sales supplies and supports DeZURIK spring diaphragm actuators for applications requiring accurate throttling, dependable shutoff, and reliable fail-safe positioning. Commonly used on butterfly, ball, plug, and rotary control valves in water and wastewater systems, these actuators provide smooth, repeatable performance for both modulating and on/off service. Our team works with engineers to match actuator sizing, spring range, and control requirements to each valve and operating condition—ensuring stable response and long-term reliability in the field.
DeZURIK rotary diaphragm actuators are engineered for consistent torque output and precise control across the full valve stroke.
Available in multiple sizes and materials to suit both corrosive and general plant environments, these actuators offer externally adjustable travel stops, clear position indication, and factory-caged spring assemblies for safe installation and maintenance.
Tek-Sales helps specify the correct actuator configuration—including fail-open or fail-closed operation—to ensure dependable performance in critical water treatment and industrial flow control applications.
PowerRac Double Acting & Spring Return Actuators
High-Torque, Repeatable Performance for Demanding Valve Service. Tek-Sales supplies DeZURIK PowerRac actuators for applications requiring dependable torque output, precise modulation, and long service life on quarter-turn valves. Designed for both throttling control and on/off operation, PowerRac actuators provide smooth, consistent motion across the full stroke—making them a strong choice for municipal water and wastewater systems where reliability and repeatability are critical. Available in double-acting and fail-safe spring return configurations, PowerRac actuators can be matched to butterfly, plug, ball, and rotary control valves across a wide range of sizes and pressure classes.
These actuators convert linear cylinder motion into smooth rotary movement while maintaining consistent torque across the entire stroke—making them well suited for butterfly, plug, ball, and rotary control valves in water and wastewater systems.
PowerRac actuators are factory-assembled, tested, and ready for installation, with a compact close-coupled design that minimizes footprint and eliminates backlash between the actuator and valve shaft. Their sealed, permanently lubricated construction protects internal components from moisture, grit, and corrosive environments, while adjustable travel stops and modular mounting allow flexible configuration in the field. Double-acting and optional spring-return configurations are available to meet both standard and fail-safe requirements.
Tek-Sales works with engineers and operators to properly size and integrate PowerRac cylinder actuators based on valve torque, operating pressure, and control strategy—ensuring reliable, repeatable performance across the life of the system.
Compak Cylinder Actuators
Tek-Sales supplies DeZURIK Compak cylinder actuators for applications where space constraints, reliable torque output, and straightforward installation are key design considerations. These rack-and-pinion actuators are available in both double-acting and spring-return configurations and provide consistent, repeatable performance for quarter-turn valves in municipal and industrial systems.
The Compak actuator’s low-profile, modular construction allows for flexible mounting in tight mechanical rooms, vaults, and skid assemblies while maintaining enclosed, protected internal components. Adjustable dual travel stops enable precise valve positioning, and a range of actuator sizes ensures proper torque matching across small- and mid-diameter valves. Tek-Sales frequently specifies Compak actuators for eccentric plug valves and resilient-seated or high-performance butterfly valves where compact footprint and dependable actuation are required.
Motor Actuators
DeZURIK maintains close relationships with all motor actuator manufacturers and can automate valves with any brand of motor actuator.
DeZURIK Knife Gate Valves are available with a wide choice of actuators including handwheel, chainwheel, bevel gear, pneumatic cylinder, hydraulic cylinder or electric motor actuators.
DeZURIK Knife Gate Valve Cylinder actuators are designed with a removable and replaceable cartridge assembly that houses the wear components for ease of maintenance. The cylinder tube is glass wound, vinyl ester, epoxy impregnated fiberglass. The seals are acrylonitrile butadiene (NBR) with a maximum temperature rating of 180ºF (83ºC). For higher temperature applications fluoro rubber (FKM) seals with the standard fiberglass tube are offered with a maximum temperature rating of 275ºF (135ºC). Steel tubes with FKM seals are available for a maximum temperature rating of 392ºF (200ºC) upon request. The minimum standard temperature rating is -58ºF (-50ºC). For corrosion resistance applications, stainless steel components are offered. All cylinder actuators are cycle tested to 50,000 cycles and are mounted to a heavy duty cast superstructure in carbon steel or stainless steel to minimize corrosion.
LA-Series Actuators are designed for use on large 30–72" (750–1800mm) DeZURIK AWWA Butterfly Valves. The LA-Series Actuator meets the requirements of AWWA C504 standards. The link-arm mechanism allows the LA-Series Actuator to provide characterized closure that slows valve travel and increases torque as the disc comes into the seat. The actuator is self-locking, maintaining valve position under varying flow conditions.
The LA-Series actuators feature an input torque capability of 450 foot pounds against the open and closed position stops as standard. An optional spur gear provides a 2:1 mechanical advantage while maintaining an input torque capability of 300 foot pounds against the stops. The spur gear slows closing of the valve, minimizing the possibility of water hammer.
Manual, Pneumatic, Hydraulic, Spring Return and Electric. Custom designed failsafe air systems are also available to prevent loss of air supply.
