8. Model FC gate valves are handwheel operated valves The gate of the MODEL FC valve is a one piece slab gate that uses two floating seats to generate a highly reliable seal The slab gate eliminates the chance of trapping pressure within the body cavity which can cause pressure locking Below are some steps which have to be followed at all times lh d Te 8 Fully open the valve before installing or shipping The sealing area of the gates in the full open position is protected by the body and is less likely to be damaged Do not remove the molybdenum disulfide coating from internal parts This coating serves as a lubricant and corrosion inhibitor To hydrostatically test the valve body to full API test pressure the valve must be in a partially open position When testing the valve in the closed position seat test do not exceed the working pressure stamped on the valve identification plate During storage always leave the valve in the fully opened or fully closed position This will tightly wedge the gate against the seats and prevent damage to the sealing area of both the gate and seats Always remove the valve from service before work is performed on the stem bearings When lubricating the body do not exceed the maximum API working pressure stamped on the identification plate The valve should be fully closed or fully opened during lubrication of the body or seats Seat lubrication pressures should not exceed the maximum allowable
