Piston Head A Meter–out poppet T C1 Command pressure Stem Spring Seat area T To tank or reservoir Figure 3. Meter-out element There are two meter-out elements, one for each cylinder port. Essentially, the CMX meter-out element is a variable orifice between one of the actuating ports and...
It gets its name because as the stem moves, the diaphragm "rolls" at the convolution. It is frequently used in a manner similar to a u-cup, that is, to seal the gap between a linear moving shaft and the valve body. SOLENOID VALVE: A valve that uses an electromagnetic coil for ...
If the valve has a rising stem its position can be seen just by looking at the position of the stem. Fig. 5.2 shows the internals of a Gate Valve that is half open. Sign in to download full-size image Figure 5.2. Gate valve. When fully open, a gate valve has no obstruction in ...
Leakproof seal forms when the metal head of the stem makes contact with the patented polymer seat in the spud. The non-metallic polymer seat resists most chemicals found in manufacturing facilities, reference the Corrosion Resistance Chart for additional information. Easy to seal Safety Notes Worn...

The diaphragm shall consist of nylon fabric bonded with synthetic rubber compatible with the operating fluid. The center hole for the main valve stem must be sealed by the vulcanized process or a rubber grommet sealing the center stem hole from the operating pressure. The diaphragm must ...
chart like Table 1 to quickly adjust the spring down to the desired rate. In the valve application the coil spring was originally guided by an adjustment screw running the spring's center. The disks springs are made with the center hole bigger to allow for clearance and a bushing above ...
