E-Ball Rotary Control Valves

Series 3800 models are eccentric, segmented ball, characterized rotary valves, particularly best suited for erosive service. Various trim selections include stainless steel, Alloy 6, and Teflon or PEEK for Class VI shutoff, or ceramic trim for slurries or gritty material control applications. Models are available in essentially any castable alloy body material. They are unbeatable for highly erosive slurries in power plants like flyash and lime slurries with the ceramic trim design.

Sizes: 1” to 8”
Two-Way Rotary, Flow to Open / Flow to Close
Body: Steel, Stainless Steel, or Custom Alloys
Temperature: -20° to 800°F
Pressure: up to 740 PSI

Lever Valves

Pilot operated 1/2” through 2” threaded bronze or stainless steel body; semi-balanced 2 1/2” through 3 flanged iron body. Lever actuators can be reversed from rising lever opens valve to rising lever closes valve.

Float Cage

The 377 Float Cage can be utilized to open a 322 or 326 lever valve to supply intake liquid to a tank. When the liquid reaches the desired level the float cage closes the lever valve to accurately maintain the liquid at the desired level. Buoyancy of its internal float ball provides the force to actuate the valve.

Vacuum Breaker

Opens gradually to admit outside air to relieve a vacuum in a tank and resets when tank pressure is restored. Features iron, steel, or stainless steel body; non-asbestos or TFE disc.

Pressure Independent Control

PICV Pressure Independent Control Valves

The PICV allows a building management system to control differential temperature to the coil or HEX and vary the control valve without external disturbances influencing flow rates. It maximizes ?T, stability, efficiency and energy savings. Designed for large complexes where attention to the carbon footprint is important. Allowing ±1 degree of setpoint versus the typical 3 degrees, equaling much less energy wasted, and much tighter temperature control.

AmurAct Fast Electrically Actuated Control Valves

The first electric actuator that replicates the speed and tight shutoff of a pneumatic and at 1% of the operating costs of making air. Think about $800/year/valve versus $8/year/valve. Made possible by an innovative, specially designed linkage that enhances a valve’s equal percentage flow characteristic providing rapid response to load changes and accurate, stable control of water, steam and common energy transfer fluids in a variety of demanding industrial and commercial applications. Warren Controls’ compact AmurAct electrically operates 1/2” through 4” control valves with shutoff capability rivaling pneumatics. It works with multiple supply voltages and signals. Electronic fail-safe needs no electrical energy to maintain lockup against elevated water or steam pressures. Stainless steel linkage construction is maintenance-free.

Building Automation

Warren Controls offers control valve configurations to meet the needs of nearly any building automation control system. A configuration is a valve body assembly, complete with an actuator that can modulate the valve plug to control flow. Stem operating forces are dependent upon packing friction, the size of the seat opening, or area of imbalance, and the differential pressure against which the valve must operate or close. Actuator selections include a variety of pneumatic and electric operators.

Electric Motor Actuated Valves

For electric actuation… power, efficiency, compactness, flexibility and economy are combined in Warren Controls Series MP and VM actuators. Ttechnology and state-of-the-art electronic control circuitry team up to provide a multitude of control features, high force output and amazingly low energy consumption. So many features are built in that add-ons are seldom needed.

Diaphragm Actuated Valves

When an air supply is available, the features of spring-and-diaphragm pneumatic actuators provide a cost effective solution. These powerful operators incorporate large diaphragm areas that in combination with the wide variety of valve types can achieve high close-off and tight shut-off. Warren Controls Building Automation pneumatic actuators use air pressure to extend their stems, and spring force to retract them, so attached stem-in-to-close valve bodies will open upon reduction or loss of air pressure (fail open), and stem-out-to-close valve bodies will shut (fail shut). Control precision, split range and close-off forces are optimized by the use of positive positioners.
