Motorized Valves and Controls



DIGI-SPAN® HWE-Elite & SEQ-3 Series

The perfect energy saving outdoor reset controls for residential and light commercial hot water outdoor reset heating applications. All of the DIGI-Elite Series controls come with a digital display, adjustable reset ratio, offset, and outdoor cutoff.


HWE-SS Single Stage – Hot water Outdoor Reset energy saving boiler control with multiple domestic hot water priority options for single stage boiler applications. Replaces the HWM 100


HWE-MOV – Provides Hot water Outdoor Reset energy saving motorized valve control. It modulates a 3 or 4 way motorized valve. Replaces the HWM 200


SEQ-3 – This control provides Hot water Outdoor Reset energy saving control for multiple boiler applications. Controls up to 3 Stages (3 on/off, 2 on/off + System pump, 1 lo/hi + System Pump, 1 on/off + System + DHW Pump). Replaces HWM 550 and HWE-Multi Stage.



DIGI-SPAN® MC-Elite Series

This series of controls senses temperature, pressure, Vacuum, or humidity and provides either an Analog 0-5V, 0-10V, 1-5V, 2-10V, or 4 to 20mA output (MCA-Elite),a Proportional 0 to 135 Ω output (MCP-Elite), and a Floating output (MCF-Elite).

In addition to set point control, the MC-Elite can operate with an outdoor sensor to satisfy Outdoor Reset applications.



Motorized Valve Radiant

The Heat-timer Radiant Valve is designed to provide superior control and reliability. The valve is primarily designed for use in Commercial and Residential Hot Water Heating Systems, controlling the temperature of a zone.



Motorized Valves (2-Way and 3-Way)

2-Way valves can modulate or turn On or Off the follow of steam. 3-way valves are used to mix water to a desired temperature. The hot water from the boiler is blended with a proportion of the cooler water returning from the system to maintain the correct water temperature entering the system.



Platinum: HWR (Hot Water)

The HWR Platinum is a hot water boiler Outdoor Reset heating control with a built-in Domestic Hot Water Priority option. It operates a single boiler and a motorized valve to achieve maximum fuel savings.

See Remote Communication, Internet Communication, BACnet communication, or Modbus Communication add on.



Platinum: MPC (Steam)

The MPC Platinum control Series is designed to operate a steam boiler or a steam valve to provide steam outdoor reset. Utilizing the steam cycle concept and the outdoor temperature, the control varies the duration of the steam supply to the building in a cycle based on the outdoor temperature. Each of these options has a set of preconfigured, but adjustable settings to meet the specific needs of each building.

The MPC Platinum will reduce fuel costs while maintaining a more comfortable space temperature.

Platinum: SRC (Vacuum)

The SRC Platinum is a sub-atmosphere steam (vacuum) systems vacuum steam outdoor reset control for . The SRC Platinum will start/stop the vacuum pump and boiler, and modulate the steam valve to vary (cycle) the duration of seam flow into a building’s radiation in accordance with changes in outside temperature.

SQ-Elite Series

The SQ-Elite is the perfect control whenever multiple stages are required for heating, cooling, pressure, or humidity applications. It will automatically activate as many stages needed to maintain precise set point control using P.I.D logic or an Over-Size System concept. In addition, it can be set to a specific set point or can use Outdoor Reset. The SQ-Elite is equipped with DHW Pump (-8T models only), and combustion air damper relays. In addition, it provides an advanced logic to protect boilers from cold returns (SQ-Elite-8T and SQ-Elite-MV models only).

The SQ-Elite-8T and SQ-Elite-MV can provide an additional output for each boiler for a boiler pump or boiler valve, which can remain active for an adjustable time delay.



Valve: ESV – Electronic Steam Valve Control

A two-motorized valve control for steam, vacuum, or hot water. It incorporates minimum valve opening settings that are beneficial to steam and vacuum systems.



Valve: ETV – Electronic Tempering Valve Control

The ETV (Electronic tempering Valve) accurately regulates water temperature for a wide variety of applications. The ETV combines a rugged stainless steel or bronze valve body, reliable electronic actuator, and a control module with PID logic.
