WebJun 18, 2014 · TRVs are two-way valves. Fluid goes in one side and it comes back out at any rate between "full on" and "full off." In other words, a TRV is very simply a proportional flow valve. It's the job of the TRV actuator to regulate the flow. The actuator senses temperature (usually room air) and has an adjustable scale. WebOct 5, 2024 · The Series “FC” flow controls can operate from 40 °F – 140°F (5°C-60°C) with PVC bodies and EPDM diaphragms. With optional polypropylene, PTFE, or Kynar bodies they can operate from 40°F- 180°F (5°C-82°C). The Series “FC” flow controls must have at least 15 PSI (1 Bar) pressure drop across the control in order to deliver the ... convert litres to m3 water WebA preset constant flow rate is maintained by automatically regulating orifice opening area, responding to changes of pressure differentials across the valve.
