Griswold Controls Automatic Flow Limiting Valve is used in many different applications, mostly in the HVAC industry to maintain balance in a HVAC System. The stainless steel flow limiting cartridge has a spring loaded cup that dynamically absorbs pressure fluctuations resulting from changing system conditions due to varying heating/cooling loads.
Automatic Flow Limiting Valves do not require any additional balancing as do Manual Balancing Valves, therefore they reduce labor costs from not having to balance and rebalance the valves.
Griswold Controls’ PIC-V®, MVP®, Pinnacle and PIM valves are Pressure Independent Control Valves. Pressure independent (PI) valves can help reduce energy costs and increase occupant comfort. PI control valves are designed to replace the conventional 2 way control valve and balancing valve pair, installed at heating and cooling coils in buildings.
Recommended applications for Griswold Controls Pressure Independent Valves include:
Balancing at reduced loads is needed, such as office buildings, schools or hotels
Temperature variance cannot be risked, such as hospitals, laboratories or prisons
When primary variable flow systems needs to be optimized
