The Interpump TIMAX TIMAX 100 pressure regulator valve is a manually- adjustable, pressure-operated device which, according to its setting, limits the pump/system pressure by conveying the excess of water to the by-pass. Moreover, when the outlet flow is blocked, this device totally releases the flow, thus keeping the pump/system at the adjusted pressure. 60 or 100 Bar max pressures. 200 Lpm max flow. 60°C max water temperature. Manual bypass lever. Brass body - Stainless steel internals.
