Two Way Control Valve Hvac

2 way valves are recommended in chilled water piping with primary const. This is partly offset by the actuators typically costing more because of the higher differential pressure across the valve. It minimizes the number of valves and actuators required which provides more control greater accuracy more efficient energy use and ultimately improved occupant comfort.

Our hvac control valves and actuators deliver consistent reliable and accurate flow rates regardless of pressure fluctuations that are inherent in any dynamic system.

Two way control valve hvac.

3 way valves are not suitable for this system. Consistent designs and convenient built in operating features provide outstanding control without requiring field add ons. 2 way valves are recommended in primary only variable speed pump. Using two way valves offers several advantages over three way valves including.

Two way valves result in variable flow that will reduce pumping energy. Please support hvac simplified for more videos like this. Fcu ahu applications of 2 way and 3 way valves. A wide variety of 2 way control valve hvac options are available to you such as graphic design total solution for projects and others.

An inlet and an outlet port typically labeled a and ab respectively. These control ball valves can be ordered alone or with spring return or non spring return actuators. 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. Flow and secondary variable speed pump.

The valve is less expensive to buy and install. The new patented johnson controls 270 six way valve and actuator signals a new direction for chilled beam and fan coil applications. 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. To maintain a minimum flow across chiller a motorised bypass valve is used.

2 way valves are pretty simple and straight forward. A 2 way valve is any type of valve with two ports. 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.
