Kwa zigawo za valve yoponya,chitsulo chosapanga dzimbirindi ductile (spheroidal graphite) chitsulo chotayira ndi awiri mwa aloyi omwe amagwiritsidwa ntchito kwambiri chifukwachitsulo cha ducitlekukhala ndi ntchito yabwino yolimbana ndi dzimbiri ndipo chitsulo chosapanga dzimbiri chimakhala ndi ntchito yabwino pakukana kutentha komanso kukana dzimbiri. Amagwiritsidwa ntchito kupanga:
- Magulu Agulugufe ndi Mpira (Ductile Cast Iron kapena Cast Stainless Steel),
- Ma disc a Butterfly Valve (Chitsulo chosapanga dzimbiri kapena Chitsulo cha Ductile),
- Mipando ya Vavu (Cast Iron kapena Cast Stainless Steel)
- Centrifugal Pump Bodies and Covers (SS kapena Ductile Iron)
- Zopangira Pampu ndi Zophimba (Chitsulo Chosapanga dzimbiri, Chitsulo chosapanga dzimbiri cha Duplex)
- Nyumba Zokhala Pampu (Grey Cast Iron kapena Alloy Steel)
