Inquiry (采购产品): Knife gate valve We want to replace a square knife gate valve about 2feet X 2feet size, pneumatically operated, installed at the bottom of fly ash silo. The one already installed is PEBCO model # 24-PA-EM-CS-A2-NB. This valve is frequently leaking. Do you have a better valve to replace this one. We will need spare seals with the new valve to replace as and when required. **** Hidden Message ***** Pawan Arora T0B 1N0 Company: ATCO Power E-mail: pawan.arora@atcopower.com **** Hidden Message ***** pawan.arora@atcopower.com
