The Hydrassist Valve is designed for use as both a hydrant booster and for inline pumping in long relay evolutions.
The valve has three modes:
Straight thru flow
Emergency shut off
The valve is connected to a hydrant or placed inline for normal (straight flow.) If pressure is low a second pumper can be attached to boost pressure without interrupting flow (boosted flow). The pumper can be disconnected without shutting down the flow (emergency shut off).
Normal operating pressure is no greater than 250 psi.
