Cast iron lever-weight valves 17ch18br are designed to discharge the medium when the pressure exceeds the permissible level on stationary steam and hot water boilers, tanks, or pipelines. They are installed in the working position in such a way that the lever is positioned horizontally, and the stem is positioned vertically. To blow out the valve, the lever is manually lifted.
The valves are adjusted to operate at the required working pressure by installing appropriate weights. Weights are not included in the delivery set. Upon the customer's request, weights are supplied for an additional fee.
