The Design Envelope IVS Twin Vertical in-line pump for commercial HVAC systems combines two variable-speed rotating assemblies in one shared casing. The twin-pump design is a variable-speed, duty/standby solution for any application that demands constant availability, energy savings, and a small footprint.

The Bell & Gossett® snap zone valve is a compact four-wire thermoelectrically operated on-off zone valve designed for heating and cooling systems. It features an innovative compact design and an adapter ring that allows for the actuators to be installed in any 360-degree position.

The NXT Series R-410A thermal expansion valve (TXV) is a balanced ported valve designed for high-efficiency R-410A air conditioning and heat pump applications. NXT Series valves operate over a wide range of conditions and applications.

A two-way pressure independent control valve, the Belimo Energy Valve™ optimizes, documents, and proves water coil performance. It uses the Delta T Manager™ algorithm to directly control coil performance. It also monitors the coil performance characteristic curve and resulting energy/power output.

Specifically designed for a wide range of flow and head requirements, the heavy-duty 0015-IFC three-speed pump is ideal for medium-sized hydronic systems where installers require maximum reliability and versatility, said the company. The circulators are offered with in-line or rotated flange orientation.

The CimCLIMA line offers a number of high-quality valves, fan coil kits, and other accessories. The valves are suitable for both heating and cooling systems, and they are designed to provide isolation, accurate balancing, and time-saving bypass that, according to the company, helps reduce energy consumption.

A line of pressure-independent control valves (PICVs) that integrate three functions into a single device — control valve, adjustable flow limiter, and automatic pressure regulator — are available. The line is engineered to offer accuracy and flexibility which simplifies planning, installation, and commissioning.

Zone Sentry™ now easily handles chilled-water applications. The valve excels in situations where condensate could be an issue for other zone valves and can be used in residential and light commercial applications, claimed the company. The plastic components of the valve’s actuator are corrosion-proof.

A complete line of Steel Isolation Valves (SIV) has been designed to provide flexibility and performance when used in any refrigeration system. The SIV products feature a unique design with a flexible three-port configuration that allows easy access to any service port, no matter where the valve may be mounted in the system.

The Speedfit® family of Twist & Lock Fittings has been expanded with the introduction of new Speedfit Secure shut-off valves, in a clean white design. The lead-free friendly valves are available in 1/2- and 3/4-inch copper tube size (CTS) sizes.
