flow. Personnel installing the operator must ensure there is 5. These are the main points of the globe valve installation position. Globe valves must always be either fully open, or fully closed once installed and are not designed or intended for throttling applications. Moreover, it is ideal to choose the same flow characteristics and size as those of control valve. On 1/2" valves, port A is the limited Cv port, unless specified otherwise. ISA shows 45 degrees from vertical as acceptable, and Gate and globe valves are shipped in the closed position to prevent damage to the seating surface during handling and shipping and should be maintained in the closed position until they are installed. 3. See the example of ideal control valve installation Example of Control Valve Installation Example of Control Globe valves should usually be installed with the inlet below the valve seat. Many valves are directional, such as globe valves, throttle valves, pressure reducing valve, check valve,etc. Blow out all piping and throughly clean below valve installation. 1. check valve is also known as a check valve or check valve, its role is to prevent the backflow of media in the 4. All globe valves operators must be assembled in the upright position vertically above the valves centerline. Gearboxes, actuators and necessary adapters must conform to the valves ISO pad top works design where applicable. 1075 Water Street Prairie Du Sac, Wisconsin, 53578 Ph. during installation Operation Globe valves must be oriented with the stem in the vertical position any time the valve is operated or cycled. Install valve with the proper ports as inlets and outlets. : 262-432-2700 Fax: 262-432-2701. 4. Make sure the innards of the valve are dry. 4. For severe throttling service, the valve may be installed so that the flow enters over the top of the seat and goes Transport or lifting a valve for installation in horizontal pipe lines as Picture 1 The lifting belts 1 und 2 must be twisted round the body. To improve positive seating, the valve can be installed in reversed orientation to provide a force down onto the plug instead of trying to push it off the seat. You would of course lose a great deal of flow capacity through a globe valve compared to a gate.and they usually cost more. Transport or lifting a valve for installation in horizontal pipe lines as Picture 1 The lifting belts 1 und 2 must be twisted round the body. Globe valve design necessitates two changes in the direction of flow and this causes resistance in liquid lines and objectionable pressure drop. Installation and use of globe valve. 6) Operate the valve from the full open to closed position. 3.2.2 Install the valve using qualified piping standards and practices. Shipping Valves need to be fully closed during shipment and actuators need to be braced to support the extra Valves must not be lifted by the handwheel! Handwheel and actuated mechanism are not allowed for lifting. Installation Globe valves must be installed and operated in the vertical position only. Handwheel operated globe valves can be installed at any position in the pipeline. 6. So regarding the The globe valve of the hand wheel and handle operated can be installed at any position of the pipeline. The installation of globe valves is made Globe valve have specific flow directions. Depending on the application, a globe valve will have fluid flow above or below the disc. Globe valves can be arranged so that the disk closes against or in the same direction of fluid flow. The flow When the valve is closed, the packing should be isolated from the media. Installation: The installation process depends on the end connection and use of the valve. (DN 150) to 8 in. Valves marked with flow direction must be installed in line with the piping flow. The ISA handbook of control valves shows automated globe control valves mounted vertically as favored position. The main installation points are below Remove any packing or debris from the valve Position 31 for Gate Valves Stud Torque ft.lbs. Torque Nm Possible Cause 1.Gland flange nuts too loose 2. 3.2.3 The recommended orientation for API 602 Forged Steel Gate, Globe & Check Valves is upright with the valve in a horizontal line with the hand wheel positioned vertically above the See piping charts on next page. 1.3 Packaging Gate and Globe Valves. 3-6> 1 Example of ideal valve...
