Norriseal 2700A Manual Includes InstallationDescription When ordered, the Valve configuration and construction The Series 2700A Valve is designed for general purpose use materials were selected to meet particular pressure, in liquid and gas Control applications calling for modulating temperature, pressure drop, and fluid conditions.Norriseal is an ISO 90 01:2008 certified manufacturer. Please refer to separate manuals for valves or other over-pressure protection devices in the instructions covering controllers and positioners. If pressure to the Maintenance information for 1" through 8" Norriseal Series Valve is capable of exceeding these limits, install relief 2700A Control valves. Maximum allowable pressures for the Valve body and Scope actuator and the maximum allowable pressure at the maximum temperature for the Valve are shown on the This instruction manual includes installation, Operation and nameplate mounted on the actuator.The Series 2700A has a single-port body some body/trim material combinations are limited in with two types of balanced trim, Plug Control and Cage their pressure drop and temperature ranges, do not apply Control. Description When ordered, the Valve configuration and construction The Series 2700A Valve is designed for general purpose use materials were selected to meet particular pressure, in liquid and gas Control applications calling for modulating temperature, pressure drop, and fluid conditions.2 Since or on/off service. Please refer to separate manuals for valves or other over-pressure protection devices in the instructions covering controllers and positioners. Fluid pressure drop occurs at the flow area between plug and seat. Flowing up under the characterized Valve plug. The Balanced Plug Control trim is used with the fluid Valve INSTALLATION AND START-UP. (spring opening) and reverse (spring closing) acting modes. Fluid pressure drop occurs at the flow area of the cage's port with the port's contour 2. Characterized ports in the cage. Before installing the Valve , inspect it for any shipment damage and for any foreign material that may have The Balanced Cage Control trim is used with fluid flowing collected during crating and shipment.3 Remove flange either down or up, depending on the application, through the protectors from body end connections. Of sizes and with a selection of springs to suit operating 4. Both actuator types are available in a range tag pinned to the body. Install Valve so that flow is in the direction indicated either reverse acting (spring closing) or direct acting (spring by flow direction arrow either cast on the body or on a opening) type. Norriseal valves are equipped with pneumatic actuators, 3. Welding slag, and other foreign materials. Upright position with actuator vertical above the body. The adjustable style is square compression packing. "V" ring style with a spring below the packing to maintain a For smooth Operation , Valve should be installed in an load. The non-adjustable packing is tape or pipe thread sealant on external pipe threads. Or non-adjustable packing. Bodies, use a suitable gasket between the body and The Series 2700A valves are available with either adjustable pipeline flanges.4 For threaded (NPT) bodies, use TFE. Connect instrument air to actuator or positioner Valve Identification connection. Do not install Valve in a system where the bonnets have an NPT thread for mounting an optional working pressures can exceed those marked on the packing lubricator. The Series 2700A 2500 class. The bodies are rated ANSI 150, 300, 600, 900, 1500 or compressor bar on the packing retainer. Table 1 relates model number positions to Valve configuration. Valve model numbers are 13 positions long with a typical model number being RF-14 AFDCT9NO. Other information applicable to the particular Valve assembly, including trim size, trim and plug materials, and pressure and temperature limits. The nameplate lists the Operation by cycling actuator several times and serial number, Series number and model number as well as observing stem movement. For valves with model codes different from those listed, consult factory. For valves with restricted trim, stem travel may be less Table 1 lists model number positions with descriptions and than the value shown.6 Some common codes and definitions.
