2 Way and 3 Way Motorized Valves for Heating Applications


When properly used, motorized valves present an elegant solution to the problems of controlling water or steam into a heating distribution system. Some common examples of these systems include:

Steam Heating Distribution – In these applications, a motorized two-way valve can control the flow of steam from the boiler or other sources into a steam distribution system. An example of this would be using steam to heat radiators in a one or two pipe steam heated building under control of something like our MPC platinum series control.

Steam to Hot Water Heat-Exchanger – By controlling the amount of steam entering a heat exchanger, a 2-way valve can maintain the hot water output temperature at the perfect temperature for delivery into the heated area of the building.  If heating load should suddenly change, these valves are automatically adjusted by something like our HWR Platinum Control to respond.

Vacuum Heating Systems – Two-way valves can modulate the flow of sub-atmospheric steam from the boiler or other sources into a steam distribution system.  These actuators are equipped with a position feedback signal.  A typical example of this type of application would be using vacuum steam to heat radiators in a building.  When the control, such as the SRC Platinum, calls to put heat into the system, the two-way valve partially modulates open and steam flows into the radiators based on the outdoor air temperature. Then when the control determines that sufficient heat has entered the radiators, the control marginally closes the two-way valve reducing the flow of steam.

Professionals want a Reliable Motorized Valve

Heat-Timer’s 2 and 3 way valve is designed for steam, vacuum, or hot water applications and has some unique features that professionals love.
    • Valve sizes from 2.5 inches to 8 inches
    • Either 2 or 3 way single seated or 2 way double seated configurations supported.
    • Low Leakage less than 0.03 % of full flow per EN1349 standards.
    • Operates perfectly under control of any Heat-Timer® Platinum Series Heating Control.
    • ANSI B16.1 Iron makes for a solid feeling, long lasting build.
    • Stainless Steel/Brass Plug material.
In applications like high pressure steam heating, the unique balance plug valve design and the double seated valve provide a distinct advantage over other valves. Our motorized valve is perfectly suited to applications where the system pressure and the differential pressure are both high. Typical applications include high pressure steam in district heating, boiler supply water, and steam heating. IN these applications, a simple connection to our MPC Platinum Control brings world class heating control and energy savings to your building.

How Heat-Timer® Controls Can Make Your Building Management System Better

A  Building Management System  (BMS), also called Building Automation System (BAS) is a system that allows building managers to monitor and control a building’s major mechanical and safety systems in one central, easy-to-use application. A BMS can be thought of as a distributed network of building systems supervised and controlled in one central platform. The network of field controllers and other system controllers are distributed throughout the building and communicate to the BMS through a local area network. Field controllers can be general purpose, supplied by the BMS integrator and used for simple applications like lighting control, ventilation fans and building access. With a BMS, these applications can also be separated by zone, floor or other combinations to yield optimal HVAC performance. Field controllers for mission critical systems like fire alarms and heating are specialized and can act independently, as well as under BMS control. The Heat-Timer® Platinum se...

Water Safety For all Time

Image
Because of regulations put in place after the outbreak of legionnaire’s disease in the 90’s, installation of Domestic Hot Water (DHW) systems were changed for the sake of public safety.  All DHW systems, whether storage based or tankless, must now meet the conflicting requirements of holding DHW at a minimum of 140°F (60°C) to comply with such standards as OSHA Technical Manual Section 3 Chapter 7, to combat Legionella growth, while delivering hot water at a temperature that prevents scalding injuries in sinks and other fixtures. For decades, commercial plumbing installers have embraced a 3 way mixing valve or “tempering valve” as the perfect solution to the dilemma. Early tempering valves were controlled manually with fixed setpoints, but in 2020 we have evolved to using motorized valves under the direction of a standalone electronic control station that adds flexibility, reduces energy use, provides alerts and alarms, and generally improves the safety of any domestic ...

Heat-Timer’s Wireless Sensor Integration Just got a Big Upgrade

Image
  One of the most appealing parts of the Heat-Timer® Platinum Series is the wireless sensor connectivity that comes with our Building Net internet upgrade. There are thousands of clients who own an original, non-internet capable Platinum Series control and when they upgrade the control with our Building Net internet package they actually get two major elements: An Internet/Mobile ready control – The Building Net upgrade gives any platinum control the ability to be controlled via the internet through a simple browser connection to a web management portal, or via our free mobile app. In either case, reports, alarms, control settings, and real-time monitoring are all at your fingertips, wherever those fingertips may be. Wireless Sensor Integration – You can think of this as the second network access that is enabled by the Building Net upgrade. This internal Long Range network allows you to connect our wireless space sensors to the control, which by reporting temperatures in vari...
