| Pressure Independent Control Valves: | |
| Griswold Controls' MVP™ is a Pressure Independent Control Valve. Pressure independent valves dramatically reduce the energy costs, capital expenses, maintenance costs, performance issues and capacity limitations associated with typical HVAC system pressure fluctuations. Pressure independent control valves are designed to replace the conventional 2 way control valve and balancing valve pair installed at heating and cooling coils in buildings. To obtain the most efficient and optimal results in a system, only the necessary amount, no more and no less, of chilled or heated water must be delivered to the heating and cooling coils at all times. This saves energy, increases available plant capacity, minimizes capital expenses necessary to acquire additional capacity, and simplifies system design and control. | |
|
Pressure independent valves stabilize flow. With stable flows, the designed heat transfer is maintained. The result is energy savings because less flow is required to achieve the same heat transfer. |
Every year billions of dollars are wasted due to the weaknesses in HVAC heating and cooling systems. If heating and cooling systems do not consistently operate at their designed temperature differential, energy waste occurs and money is needlessly thrown away. This unnecessary expense can be eliminated by using Griswold Controls' pressure independent valves. |

| Features/Benefits | |
| Feature | Benefit |
| MVP™ Valves offer pressure independent control | Provides balancing at any point below and including max. flow rate, eliminating hot and cold spots in a building. |
| MVP™ valves reduce energy required to produce and distribute hot and chilled water | Increases chiller efficiency by 15-20% and increases Delta T across coils, thereby heating and cooling more space with less equipment and energy. |
| MVP™ valves experience no change in flow regardless of the pressure fluctuations up or down stream of valve. | Requires less work for the actuator and increases actuator life. |
| MVP™ valves are pressure independent, multi-function modulating 2 way control valves | Combines differential pressure control with modulating control into one compact valve housing. |
| MVP™valves reduce valve and actuator hunting by compensating for pressure changes in system. | Increases occupant comfort, and extends both actuator and seat life. |
