WebIf the water temperature drops to 50°F, the required flow rate for this equipment in the heating mode expands to 5 GPM/ton (= 15 GPM total). With a 45°F source water, the same unit now requires a flow rate of 10 GPM/ton (= 30 GPM total). Water temperature has the opposite effect in a cooling mode. WebFast-Switching Two-Speed Two-Action ElectricallyOperated Air Directional Control Valves. Run through equipment cycles up to 30% faster than with standard valves. These valves shift between flow positions in 1. 7 ms. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which ...
