Taco Zone Sentry zone valves provide on/off, normally closed control in closed hydronic systems. The unique patented technology in the Zone Sentry utilizes a microcircuit based logic to control a gear driven electronic actuator which drives a ball valve based body design. The valves can be used in a wide variety of heating and condensing cooling applications, primarily designed for use with baseboad, fan coils, radiators, convectors, air handlers, heat pumps and radiant applications.

The versatile Setpoint version of the Varailble Speed 00 can be set up to deliver a fixed temperature, maintain a specific temperature drop between sensor locations, used as a bypass/shunt pump or integrated into a fan coil package to vary the speed of the pump based on supply air temperature. The 007-VS can be either direct acting or reverse acting.
The 1600 Series has a maximum operating pressure of 175 psi, and a maximum operating temperature of 300 F. Replaceable "cooler running" bearing cartridge extends bearing life, and with permanently sealed greased lubricated ball bearings it is virtually maintenance free. Pressure tappings allow for differential pressure readings to be taken across the pump. Dynamically balanced stainless steel impeller assures long life and higher pump efficiencies. Non corrosive shaft sleeve protects the shaft by preventing contact between the shaft and system fluid eliminating the need for more expensive corrosion resistant shaft materials. 1600 Series In-Line pumps utilize a Type 21 seal design which facilitates quick and easy replacement. One size seal fits all models. Flexible coupler absorbs shock, vibration and misalignment that could be transmitted to the cartridge and motor bearings while also isolating and preventing any motor related noise or vibrations from being transmitted to the system. Resilient mounted motor insures quiet reliable vibration free operation of the pump. Superior parts flexibility: one cartridge, one seal, and two motor frames fit all pump models. All 1600 series pumps are factory tested, and are built in accordance with Hydraulic Institute Standards.
2 way Injection, 3 way mixing - Operates off constant power or relay end switch - Ball valve design - Manual operation button - Solid state microprocessor design - Compact design - Easy one handed actuator removal - 125 PSI shutoff pressure - Plug in low voltage connections - Multi-status LED indicator light - Fail safe mode - Sensors included - Selectable maximum supply temperature (110F, 130F, 150F, or off) - Selectable minimum supply temperature (85F when maximum supply temperature is set to 150F or off ) Adjustable minimum boiler return temperature (120F, 135F, or off ) - Warm weather shutdown (70F or off) - Adjustable heating curve (0.2-2.2 reset ratio) - Use the Taco Outdoor Reset iSeries Mixing Valves instead of a conventional injection system. With a full featured outdoor reset control built right into the actuator there is no need for an externally mounted reset control or expensive control valve. The iSeries valves can also be set up to do zone by zone outdoor reset, providing optimal comfort control for every zone. The direct drive actuator modulates a 3 way valve that injects different rates of hot water, supplying virtually any water temperature to the heating system. Working off an adjustable reset ratio, the valve's maximum and minimum system supply temperatures can be adjusted to support all types of jobs, including staple up radiant floors that require a higher starting temperature. The iSeries valves include an adjustable boiler protection function which prevents low water temperatures from returning to the boiler. With a multi-status LED indicator light, plug-in wiring connections and an easy to remove actuator, the installation could not be easier.

It is a shut off Valve, a non slam check Valve, a balancing valve, a flow metering valve, and now it is field convertible from a straight pattern to a 90 degree right angle pattern. In addition, the Plus Two multi purpose valves have low pressure drops, equal to or better than any valve on the market today, and the stem seal packing can be replaced under full system pressure.
The PC605 Priority Protection Plug In Card is a solid state control that helps prevent freezeups in the event of a priority zone failure. If the priority zone calls for heat continuously for more then one hour, power is returned to the space heating (non priority) zones, allowing all zones to function independently. Once the priority zone is satisfied, the PC605's auto reset is activated and the priority zone is again allowed to have priority for up to one hour the next time it calls. The one hour time frame is not adjustable.The red LED light is energized only when the Priority Protection Card is operating in priority override mode.

Taco PAX partial acceptance bladder captive air expansion tanks are applied in commercial, institutional and industrial applications for the control of pressure in potable systems. PAX bladder tanks use a field replaceable bladder to permanently separate the air and water This permanent separation allows the tank to be precharged on the air side to the minimum operating or fill pressure. The precharge eliminates the many gallons of water typically used to compress the atmospheric pressure found in a plain steel tank application. A reduction in the required tank size when incorporating a captive air expansion results in tank sizes of up to 80% smaller when compared to air cushion or plain steel tanks. In a PAX bladder tank the partial acceptance bladder is not attached to the tank wall like a diaphragm tank. Rather it sits in the bottom of the expansion tank utilizing an internal assembly connecting to the stainless steel system connection located on the top of the tank. The partial acceptance bladder inside the tank operates very much like a balloon. It is critical to the sizing of any partial acceptance tank that both the bladder acceptance volume and total tank volume be adequate to accept the net system expansion volume without exceeding the pressure limitations of the system design. Taco is pleased to offer a selection app for the selection of these styles of tanks. Expanded water flows into the inside of the bladder. The air/precharge is on the outside of the bladder between the bladder and the tank. As a result no water is in contact with the tank wall minimizing corrosion. In a partial acceptance bladder tank the bladder is of limited acceptance volume and does not stretch.
Digital Timer can be programmed to operate at different times on different days, weekdays or weekends, for maximum comfort and convenience to match family schedules. Easy circular programming clock face and LCD readout screen. Run time intervals as short as 1 minute provides maximum energy efficiency. A capacitor backup saves settings for up to 2,500 hours during power outages.

The Taco 409 air vent is a heavy duty brass vent rated to 150 psi system operating pressure. The conical shapeof the vent significantly increases the clearance between the water level and internal mechanisms, reducing the potential that dirt floating on the top of the water could foul the venting operation. It features a convenient outlet connection for a 3/4 ID flex tube waste connection. It’s high capacity design makes it ideal for placement throughout commercial systems
Designed for high head, open system zone control. The unique end switch design permits control of the heat pump by the valve. This allows movement of cold water into the coil before the heat pump actually starts.
Microprocessor PI control (NOT a limit control!) - One outdoor air sensor - One supply water sensor - Domestic hot water demand control - Interstage delay - The Taco Two Stage Boiler Reset Control is a microprocessor based control designed to regulate the supply water temperature from a two stage boiler system based on the outdoor temperature or domestic hot water requirements. To avoid boiler short cycling and large temperature swings, the PC700 is able to continuously adjust the boiler differential. Standard functions include warm weather shut down, minimum boiler supply temperature setting, and a starting water temperature setting. The updated Boiler Reset Control utilizes an easy to use automatic reset ratio calculation to set the relationship between outdoor temperature and supply water temperature (heating curve) to provide optimum control and comfort. The control has a liquid crystal display that clearly shows the boiler supply temperature as well as the other monitored temperatures and settings
