Inquiry (采购产品): dumping valve Dear Sir I am looking for a valve I know as a dumping valve. On the net, the term dumping valve is used for a different sort of equipment. I will describe it to you and perhaps you can tell me what it is more commonly called and where I can find it. Picture a valve with one port attached to a municipal water system and a second port attached to a tank. The valve has a lever on it. When the lever is pushed one way, water from the mains is let into the tank. When the lever is pushed the other way, water is dumped from the tank through a third port. The quantity of water allowed through when the valve is pushed either way need only be very small but the amount of pressure needed to push the lever should be as small as possible. A longer lever culd be a partial answer to this requirement (more leverage). Many thanks Willim W.
