Two Way Control Valve Hvac

An inlet and an outlet port typically labeled a and ab respectively.

Two way control valve hvac.

The new patented johnson controls 270 six way valve and actuator signals a new direction for chilled beam and fan coil applications. Two way valves result in variable flow that will reduce pumping energy. To maintain a minimum flow across chiller a motorised bypass valve is used. Consistent designs and convenient built in operating features provide outstanding control without requiring field add ons.

A wide variety of 2 way control valve hvac options are available to you such as graphic design total solution for projects and others. The vbn2 2 way control ball valves and vbn3 3 way control ball valves control hot and chilled water with glycol solutions up to 50 in heating ventilating and air conditioning hvac systems to provide two position or modulating functions. Please support hvac simplified for more videos like this. Using two way valves offers several advantages over three way valves including.

3 way valves are not suitable for this system. This is partly offset by the actuators typically costing more because of the higher differential pressure across the valve. 2 way valves are used in many applications from basic on off to more complex variable flow applications with pumps and vfds. In chilled water line criteria to use2 or3 way valve depends on the application type.

Flow and secondary variable speed pump. It minimizes the number of valves and actuators required which provides more control greater accuracy more efficient energy use and ultimately improved occupant comfort. Fcu ahu applications of 2 way and 3 way valves. 2 way valves are recommended in chilled water piping with primary const.

The vb30a two way ball valve assemblies are used in heating ventilating and air conditioning hvac systems for two position or modulating control of low pressure steam water or glycol solutions to 50 percent concentration. The valve is less expensive to buy and install. 2 way valves are pretty simple and straight forward. Our hvac control valves and actuators deliver consistent reliable and accurate flow rates regardless of pressure fluctuations that are inherent in any dynamic system.
