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.

Belimo Valve Assemblies

Whether you need  PICCV, CCV, globe,butterfly, ball, or others, Belimo has reliable valve assemblies and e-controls.net has your needs covered at the best prices with outstanding customer service.  

Pressure independent valves are not affected by pressure fluctuations in the system.  By precisely controlling the flow, the pressure independent valves eliminate the need for balancing valves. The biggest benefit comes in the form of energy savings by eliminating overflow wastes energy by over pumping. Characterized control valves mark a true advancement in control valves. It combines the high close-off capabilities of a ball valve with a specialized disc that ensures a true equal percentage flow characteristic. The comprehensive line of globe valves, butterfly valves and ball valves fulfill the requirements of many HVAC applications. Globe valves are the perfect fit for such applications as unit ventilation and air handling units as well as other water/steam control. Butterfly valves fulfill the requirement of commercial and industrial HVAC applications.

Belimo Energy Valve

Belimo Energy Valve™

Are you suffering from Low Delta T?? Check out the Belimo Energy Valve. It is a two-way pressure independent valve that measures energy and controls power. Using the Electronic Pressure Independent Valve (ePIV) platform, the Energy Valve measures the coil energy using an electromagnetic or ultrasonic flow sensor, water supply, and return temperature sensors.  It also manages the Delta T. In addition to the standard analog signal and feedback wiring, it communicates its data to the Building Management System via BACnet MS/TP or BACnet IP. The valve is available in non-spring return and electronic fail-safe products.  The built-in web server collects up to 13 months of data that can be downloaded for further use.
