Fail-safe zone valve actuators connect to compatible zone control valves to control which sections or zones are connected to the water or steam distributed by the HVAC system. They feature an integrated spring return that will force the valve into a specific position in the event of power or control signal loss.

Fire- and smoke-rated actuators provide fail-safe control over infrastructure components during a fire. They feature fail-safe mechanisms that withstand higher temperatures than regular fail-safe actuators and are designed to work rapidly during an emergency. This helps ensure occupant safety by preventing the spread of smoke and flame.

Dual-temperature thermostats allow users to determine two separate temperature setpoints for different times of the day, week, or year. They save energy costs for schools or commercial buildings that are occasionally unoccupied. When the supply pressure to the unit changes, the thermostat automatically switches between the setpoint temperatures. Some thermostats also have a manual indexing switch that allows users to restore the prior temperature setting of an individual thermostat without affecting other thermostats in the system. The indexing switch can be unlatched manually, or it will automatically reset with the next cycle. These pneumatic thermostats are powered by compressed air.

Mounting brackets create a secure point to install actuators and ensure they remain connected to the equipment they actuate.

Designed to overcome the limitations of traditional actuators, LEGRIS axial valves combine the functions of a valve fitted with an actuator. Extremely compact, axial valves need up to 50% less space than actuated valves.

These thermostats have a digital display and control temperatures of two- and four-pipe fan coil unit (FCU) systems. FCUs use a coil and fan to heat or cool a room. Indoor air moves over the coil to be heated or cooled before being released into the room. These thermostats allow for multiple settings of the fan's output to gradually heat or cool the room to the desired temperature. They're often installed in hotels, multifamily housing, schools, and other residential and commercial locations. These thermostats are nonprogrammable, so the temperature setting stays the same until it's readjusted.

Nylon and nickel-plated brass push-to-connect tube fittings are compatible with a variety of tubing and are suitable for most air applications. Nylon is a strong plastic with resistance to chemicals and corrosion. Brass, an alloy of copper and zinc, is strong and resists corrosion from water, heat, acids, minerals, and peaty soils. Nickel plating increases its corrosion and wear resistance.

Standard copper soldered tube fittings connect to copper tubing or other fittings by heating or soldering for a permanent, leaktight connection. These fittings are suitable for plumbing applications with potable water.

Class 150 threaded zinc galvanized steel fittings connect with medium-pressure (300-999 psi) pipe. Threaded pipe fittings use PTFE tape to secure seal.

Rectangular fire dampers have a fusible link that triggers above a specific temperature and closes shut using spring-loaded blades or gates. They eliminate the spread of fire through the HVAC systems.

Self-retracting cord reels have a spring mechanism that automatically winds the cord back on the reel, making them easier to use than hand-winding cord reels. A stop, or ratchet, holds the cord at the desired length after it's pulled out for use. A quick tug on the cord disengages the stop, causing the spring to fully retract the cord. These reels provide access and storage of extension cords while protecting the cord from wear, tangling, and kinking.
