SAFETY Caution must be taken as to the surrounding area and its potential dangers of projectiles. Pressure kills Even a loose, stand alone valve may contain trapped pressure which will turn any component into a projectile missile when disassembled, causing injury or death. Never stand over a component or in its path of release during assembly. Always operate the valves from the open to close position slowly releasing trapped pressure. Always remove fittings first, taking extreme caution to their potential danger as a projectile. If the valve is frozen and can not be operated, take extreme caution to the disassembly of the components. Weighted blankets or protective screens and shields should be utilized. Caution should be taken when handling components during disassembly and assembly, as most components are heavy, greasy, hard to handle and have edges which can cause injury. Always be cautious of how the valve is positioned and standing. Be sure the valve is secured in position so there is no possible chance of tipping over. Never apply test pressure above the manufacturers rated working pressure. The shell test pressure above the working pressure has already been tested by the manufacturer and is not required after the initial assembly test of the valve. The manufacturer has already verified the quality of the valve shell body components and will void the warranty from the manufacturer if the valve is pressure tested above the rated working pressure indicated for the valve. Always wear steel toes shoes, hard hat, eye and ear protection while pering repairs.WWW.VALVEWORKSUSA.COM SALESVWUSA.US PROPRIETARY BOOKLET OF VALVEWORKS USA.

The gate of the MODEL FM2 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. Fully open the valve before installing or shipping. The sealing area of the gate, 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 prevent damage to the sealing area of both the gate and seats. Always remove the valve from service before work is pered 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 API test pressure. This of operation will prevent damage to the sealing surfaces of the gate and seats, and will increase the life of the valve.WWW.VALVEWORKSUSA.COM SALESVWUSA.US PROPRIETARY BOOKLET OF VALVEWORKS USA.

Foreign matter trapped in the body may become lodged between the sealing surfaces of the gate and seats, resulting in scored or damaged sealed. Venting a Model FM2 valve is a positive of checking the sealing ability of the gate and seats. If the body vents down to zero pressure with the valve in fully closed position, this is definite indication that sealing surfaces are in good condition. MODEL FM2 SERVICE AND OPERATION MANUAL/p
