Mounting and Assembly of Sandwich Bodies

Transcription

1 Mounting and ssembly of Sandwich odies Mounting of ISO 0 (CEO ) Sandwiches Many of Sun s ISO 0 (CEO ) sandwich bodies are designed for multi-functional use to permit maximum circuit flexibility. With the exception of a limited range of sandwich bodies, Sun ISO 0 (CEO ) sandwich bodies do not have a counterbore for installing O-ring seals. Instead, Sun uses a special seal plate with a raised and a locating NOCH. Sun bodies incorporate oversize, symmetrical mounting holes to allow the bodies to be rotated about the Y axis and the X axis as shown in Figure. Rotation about the Y axis enables the and port connections to be interchanged and rotation about the X axis enables the and ports to be interchanged. ll Sun seal plates are manufactured to accommodate current industry standards regarding port and mounting bolt locations. Each Sun ISO 0 (CEO ) sandwich body is supplied with a 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 bodies are located properly, all ISO 0 (CEO ) 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 (CEO ) Sandwich odies stamped with numbers to orient body for desired function he function symbols on the data pages for Sun s ISO 0 (CEO ) sandwich bodies (see Figure on page ) 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. he Meter-out and Meter-in functions are shown in the symbols with the numbers and, which stamped on the opposite face of the body. Sun Hydraulics echnical ips 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. 50 (,7mm) Diameter, laces for -- 0 O-rings ssembly of ISO 0 (CEO ) Sandwiches....

If a valve stack requires disassembly at anytime, the pin should not be removed. It will simplify the reassembly of the valve stack. NOE: Not all manufacturers of subplates offer a pin clearance hole which requires the pin to be omitted. 5. fter all the body alignments have been determined and all pins installed, assemble the valve stack in the required functional order. 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. (,5 5,0 Nm). Steps to void Seal late Leaks Make sure the mounting surface is flat and without burrs. Do not polish the mounting surface. (Machining marks help to keep the O-rings from acting as pumps.) Remove any dings on the corners of seal plates that could create gaps. Studrods or cap screws must not bottom out in the threaded mounting holes. It is very important to keep all of the o-ring sealing surfaces dry. he hydrostatic properties of an oil film under the o-rings, and at the seal plate interface, can SE SE egin with body view showing stamped number in lower left corner.

Warning: If you start with a wet seal interface in your stack, there s a good chance it will always stay wet! Orientation Example for ISO 0 (CEO ) bodies Steps through in Figure on page describe in detail the steps for the orientation of a G sandwich body. Mounting ISO 05 (CEO 5) Sandwich odies Sun ISO 05 (CEO 5) sandwich bodies are available for many mounting configurations. he standard ISO 05 (CEO 5)/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 Y axis. Sandwich bodies that can be rotated will use a Sun seal plate supplied with the body. Non rotating bodies will have counterbores machined into the body sealing surface for O-ring placement. he ISO 05 (CEO 5) sandwich body can only be rotated about the Y axis referred to in the ISO 0 (CEO ) sandwich section. (here is no on the ISO 05 (CEO 5) subplate,) X axis rotation is not possible due to the lack of symmetry of the fluid ports. Mounting ISO 05 (CEO 5) x, y Sandwich odies Sun ISO 05 (CEO 5) x, y 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 must be ordered separately to correctly match the other valve bodies in the stack.

Once the rods are installed in a subplate or manifold, they act as a guide in assembling the sandwich body stack. fter the directional control valve is assembled on top of a stack, Sun studnuts are used to retain the assembled stack. he inch and metric studrods are both made of high tensile, fully threaded SM--9 Grade material with the following mechanical properties: 5,000 psi (86 Ma) minimum tensile strength. 05,000 psi (7 Ma) minimum yield point. 6 Rc hardness. he studnuts are special hex socket nuts with the following features: n outside diameter equivalent to a standard socket head cap screw.
