Sandwich Bodies TECHNICAL PRODUCT INFORMATION

Transcription

1 Sun offers sandwich and subplate mounted bodies for most of its cartridge functions. hese mounting configurations are complete circuit elements that mount under directional control valves. Similar to other Sun mounting configurations, the sandwich and subplate bodies are available in aluminum and ductile iron material. he sandwich and subplate bodies are available in five different interface patterns as shown below: Mounting of ISO 0 Sandwiches Sun s ISO 0 sandwich bodies are designed for multi-functional use to permit maximum circuit flexibility. Due to this versatility, the ISO 0 sandwich bodies do not have a counterbore for installing O-ring seals. Instead, Sun uses a special seal plate with a raised NI and a locating NOCH. Sun bodies incorporate oversize, symmetrical mounting holes to allow the bodies to be rotated about the NI axis and the longitudinal axis as shown in Figure. about the NI axis enables the and port connections to be interchanged and rotation about the longitudinal axis enables the and ports to be interchanged. ll Sun seal plates are manufactured to current industry standards regarding port and mounting bolt locations. Each Sun D0 sandwich body is supplied with a NI locating hole which is drilled on each mounting face to position the body in the correct relationship to the ports and mounting holes. o further ensure that all ISO 0/NF D0 ISO 05/NF D05 ISO 05/D05 with ISO 05/D05 with ISO 07/NF D07 ISO 08/NF D08 and U.S. and CEO.50 Diameter - laces for -0 O-rings.0 Diameter laces on the xis Longitudinal xis Locating in Hole NOCH NI xis NI xis.05.0 Locating in on the Longitudinal xis Figure : ody Reference bodies are located properly, all ISO 0 sandwich bodies are stamped with an arrow (or arrows) to show the relationship to the notch in the seal plate (see Figure ). Multi-function bodies are NOCH stamped for all possible mounting positions and all positions should be carefully inspected to be sure the intended function is correctly installed. ISO 0 stamped with numbers to orient body for desired function he function symbols on the data pages for Sun s ISO 0 sandwich bodies are shown with numbers (,,,) in the upper right and lower left hand corners. hese numbers correspond to numbers stamped on the face of the bodies and designate the functionality of the product. ecause many of these bodies can be used for different functions, the bodies are stamped to help the user orient the body for the function desired. Some bodies can be mounted in four different orientations, as shown in Figure on the facing page. he example below shows G. s demonstrated by the function symbols, this single body can be used to achieve four different functions: Meter in, Meter out, Meter in, and Meter out. he body drawing only indicates the Meter out and Meter in orientations because only one face of the body is shown. he Meter out and Meter in functions are shown in the symbols with the numbers and, which correspond to the numbers stamped on the opposite face of the Example for ISO 0 bodies using subplate G.

Make sure all the O-rings are properly positioned. Install the directional control valve on top of the stack and tighten the stud nuts alternately to the proper torque of 0-5 lb. in. Mounting ISO 05 Sun ISO 05 sandwich bodies are available for many mounting configurations. he standard ISO 05/NF D05 is offered with two methods of sealing the fluid interface. he sealing method depends on the ability of the body to be rotated about its axis. Sandwich bodies that can be rotated will use a Sun seal plate supplied with the Non rotating bodies will have counterbores machined into the body sealing surface for O-ring placement. he ISO 05 sandwich body can only be rotated about the NI axis referred to in the ISO 0 sandwich section. here is no NI on the ISO 05 subplate, it is used only for axis reference. Longitudinal axis rotation is not possible due to the lack of symmetry of the fluid ports. Mounting ISO 05, Sun ISO 05, sandwich bodies are furnished with pilot and drain connections. Due to the differences in the U.S. and European seal plates, none are supplied with these bodies. hey US Selected ssemblies Catalogue #
