Pre-insulated Ball Type Non-return Valve - Reinforced Rubber & Leaded Tin Bronze, Low Pressure Drop & Self-cleaning Design

Pre Insulated Ball Type Non Return Valve

Valtree Ball Type NRVs (Non-Return Valve) are unique and simple design but robust design with no critical mechanism involved. All parts like hinge-pin-disc mechanism used in conventional valve are eliminated and Valtree has put in a reinforced rubber coated ball to arrest flow media in return condition. This ball moves totally out of the flow path when the pumping is on to give minimum head losses. The spherical rubber coated ball seals perfectly on the rounded valve seat ensuring a totally leak proof sealing. This design offers other advantages like non-clogging & self cleaning. In this virtually maintenance free valves if required after prolonged usage the on-line replacement of the balls is just a minute job.

The Key Features

The heart of this valve is a reinforced rubber ball. The unique design of the valve allows free movement of the ball. The ball moves to open position when the pump starts & allows free flow of liquid without any interference. As the pump stops the ball seats firmly against the metal seat due to its own weight & back pressure of the liquid. This results in DROPLESS sealing.
