The Model D-2 is a double check assembly. Production began approximately 1978 and was discontinued in 2003. The valve is a bronze body with poppet type check valves. The check poppets are either stainless steel or delrin plastic. Check seats are replaceable. A seat removal tool is needed to change the check seats. Check springs are not contained when the covers are removed. The valve uses the check design as used in the RP2 series.
