Why Cross™

Smart Hydronic Distribution with a Window into Every Zone.

A pre-assembled distribution and zoning system designed for a wide range of hydronic heating applications, with clear real-time visability of every zone.

Metal plumbing manifold with four valves, pressure gauges, flow meters, and attached white pipes.
Cross Manifold device with metal frame, blue central component, and labeled terminal connectors on top.
Cross Manifold plumbing system with gauges, valves, and flow meters on stainless steel pipes.
Never-Seize PTFE Valve System
The 100% PTFE valve stem is designed to resist sticking and provide dependable long-term operation.
Viewing Window Technology
Observe actuator movement and zone operation in real time through the integrated viewing window.
Up to 99% Less Actuator Energy
Cross uses energy only while moving a valve between its open and closed positions. Conventional thermal actuators must remain continuously energized to hold a valve open.
Precision Zone Control
Control each zone independently for consistant comfort and efficiecy.
Simple Wiring System
Integrated controls and plug-n zone connections simplify wiring and reduce installation time.
Why Cross Ultra™

Maximum Performance,
Minimal Footprint.

The Cross Ultra™ delivers the same advanced zone control and PTFE ramp-valve technology as the Cross™ system in a low-profile package engineered for concealed installations.

Ultra-Low Friction Ramp Valve Technology
Engineered to resist sticking and provide dependable long-term operation.
Low-Profile Design
Designed to fit within standard 4-inch (100 mm) wall cavities and concealed spaces.
Up to 99% Less Actuator Energy
Cross-Ultra consumes power only while moving a valve. Conventional thermal actuators must remain energized to hold a valve open.

How Cross™ Works

The Cross™ Linear-Actuation Platform

The Cross™ is a patented intelligent drive system that operates every zone using a single precision actuator assembly.

Metal plumbing manifold with four white pipes, flow meters, pressure gauges, and valves for fluid control.

LINEAR DRIVE & CARRIAGE
Precision lead screw and linear carriage deliver smooth, accurate travel across the manifold
Cross section of a black mechanical valve with a white internal lining and blue locking clips.
ACTUATOR ENGAGEMENT
The actuator engages the selected valve using controlled linear motion for reliable operation.
01
LINEAR DRIVE SCREW
Precision lead screw moves the actuator carriage smoothly across the manifold to any zone location.
02
DUAL-MOTION™ ACTUATION SYSTEM
One motor positions the carriage. A second motor engages the actuator cam and operates the selected zone.
03
ON-DEMAND ACTUATION
Power is consumed only while a valve is moving. No continuously energized thermal actuators are required.
04
ANTI-JAM™ CONTROL TECHNOLOGY
Postion feedback monitors carriage movement and alerts the user to a potentially obstructed valve.
05
ULTRA-SYNC™ POSITION TRACKING
Proprietary Cross position tracking technology confirms exact carriage location and zone status in real time.
06
INTELLIGENT ZONE MANAGEMENT
The controller tracks which zones are open or closed.
How Cross-Ultra™ Works

The Cross-Ultra™ Smart
Actuation Platform

The Cross-Ultra™ is a patented intelligent drive system that operates every zone using a single precision actuator assembly.

01
PRECISION LINEAR MOTION
Lead screw driven carriage travels smoothly between zones for accurate positioning
02
SMART VALVE ENGAGEMENT
The actuator engages only the selected ramp valve. No dedicated actuators are required at each zone.
03
UP TO 99% LESS ACTUATOR ENERGY
Energy is used only during zone transitions. No constant electrical draw.
04
ULTRA-SYNC™ POSITION TRACKING
Proprietary Cross position tracking technology confirms exact carriage location and zone status in real time.
05
ANTI-JAM™ CONTROL TECHNOLOGY
Postion feedback monitors carriage movement and alerts the user to a potentially obstructed valve.
06
INTELLIGENT ZONE MANAGEMENT
The controller tracks which zones are open or closed.
