Product Spotlight: Johnson Controls V46 Series of pressure actuated modulating valves.

Produced for both refrigerant systems as well as saltwater applications, the V46 series from Johnson Controls features numerous benefits.  This series was designed to be “direct-acting” with quick open option on increased pressure, and “reverse-acting” to close on pressure increase.  These devices control water flow to a condenser by sensing the changes in pressure through a refrigerant cycle.

The valve design is pressure balanced so that the setpoint is separate from the water inlet pressure.  These include pressure resistant bellows where refrigerant pressure grows up to 28-bar.  Likewise, the V46 series is pressure-actuated for fast and direct variations in pressure. They offer a high flow capacity with their smaller dimensions, in both angled body types and straight line, available in 3/8”, ½” and ¾” for a high Kv value.

The V46 pressure actuated valve with angled body type

Other features include:

Reduced Hysteresis: The close fitting and sliding parts are within water passages.

Easily Disassembled/Replaced:  Valve is designed for easy repairs “in line”.

Durability: bodies and monel parts are made of special bronze, excellent for sea water applications.

Power Elements:  Some models include stainless steel bellows for applications with ammonia filled equipment.

Connection Styles Options:  A wide range of types to meet various requirements.

Nickel Plated Seats:  available on valve sizes of 3/8", ½" and ¾” openings, they offer resistance against corrosion, cavitation and erosion.

Control Action:  Direct or reverse action can be factory changed to suit your application.

JCI notes that all of the V46 series regulating valves were designed as operating devices only.  In several applications where valve failure might result in personal injury or loss of property, it is required to install a separate safety shut off valve.

The New Generation NFB/NFX series of spring return actuators was designed for several applications including control valves, make-up air units, retrofit, replacement and control dampers designed up to 22 square feet. 

The NFB24 Damper Actuator

Here are some of the benefits and features of the series:

• Torque: With 50% more than previously offered, the NFB series now boasts 90 in-lbs of torque.
• Smaller Housing:  The re-design of the body features a reduced footprint with the edge to shaft-center distance shortened by .75” which makes the device easier to install in tighter spaces.  
• Manual Override:  Now standard on all NF Series configurations.
• Power: UPS can accept 24 VAC (up to 24) VAC.  The actuator is ideal for all power supply voltages.
• Cable length options: Now offered are 3’, 10’ and 16’; same as the non-spring return models.
• Mechanical limit stop:  This is now built-in, and no longer a separate accessory.

Belimo Damper Actuators provide versatile operation and yield energy savings with their low power usage.  They perform reliably and safely, by utilizing rugged components.  They communicate directly with BAS (Building Automation Systems) via BACnet, Modbus or MP-Bus.  Finally, they offer unsurpassed accuracy and control without loss in their performance due to supply voltage, temperature, or speed.

Choose Greystone Energy Current Sensors and Switches For Power Monitoring.

For whatever your power and current monitoring needs are, you can rely on Greystone Energy’s line of current sensors and switches, suitable for a variety of applications.   There is a series sure to meet the project requirements at any level.  Let’s take a quick overview of Greystone’s current offering.

CS Mini Switch

CS Mini Switch Series 

Model CS, is a series of mini current switches that monitor line current.  Suited for electrical loads such as lighting, conveyors, pumps, heaters and fans.  When the trip point is exceeded, the output contacts close.  0.5 Amps is the factory set trip point on the CS-GnG-100, and the CS-610-75 model is field adjustable for .75 to 75 Amps simply by knob rotation.  The CS Series minis have no external power requirements, rather it is powered via the AC line’s induction that’s being monitored.

CS Switch Series

CS Switch Series

A step up from the Minis, is the standard CS Series that have a factory-set trip point of .75 Amps on the model CS-GnG-200 and a range of 1 to 200 Amps on the CS-610-200, which is field adjustable.  Again, powered exclusively from the induction of the AC line which is monitored.

SC Switch Series

SC Switch Series 

The Model SC is a series of AC current switches which are "split-core".  These solid-state switches activate contact closure when monitored current surpasses a pre-set level. There are several versions for the switching of various loads. Built in LEDs display switch status and device power. Capable of monitoring to 200 Amps continuous, this series has the added benefit of an auto-range circuit, replacing manual jumpers.

CS-425-HC Series

CS-425-HC Series

For high output current switch needs, seek the model CS-425-HC.  A solid-state switch that includes Normally Open TRIAC outputs to monitor and control high-current AC loads.  These also feature internal circuits powered via the induction monitored.  Loads can be switched from 120 VAC to 2.5 Amps by the device output.

CS625 Series

CS625 Series

Greystone's CS-625 is a high output AC current sensor, which is customarily used in motor control providing On/Of Status, motor failure, belt loss and proof of operation.  External power not required.  Capable of switching loads up to 1 Amp or 240 VAC.
