INTERPUMP UNLOADER VALVES & ACCESSORIES

The Interpump BH210, H235, HM1, HX and UNICONTROL automatic pressure regulator valves are 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 – and keeps under pressure the portion of the system following the valve, while it sets the pressure to zero in the portion of the system preceding the valve.
