Multi-Power Air Presses

Provisions for operator protection are always the full responsibility of the user Page 10 Multi-Power ® Air Presses Specifications subject to change without notice or incurring obligations The “RV” Valve, with its unique poppet type seal, senses the pressure being applied and opens at your pre-adjusted set point to provide a pilot signal for circuit control. Because force is a direct function of pressure times area, the “RV” provides direct and precision adjustable force sensing. If the application requires that a predeter- mined force be applied to an object at a point that may vary in physical dimensions (such as crimping, riveting, etc.) the “RV” is the control to use. It assures that the predetermined force (pressure) is applied regardless of variations in parts thickness. If the system pressure should drop below the “RV’s” set point, the valve cannot open. The cycle will stop and wait for the required pressure rather than produce an unaccept- able rivet or crimp. Once the required pressure is restored, the cycle will continue.

One Shot (Pulse) Valves Cut-away view of RV-2 Sequence Valve Flow Control Needle Valve Cut-away view of Model 18DP-4 This 1/8 NPT ported valve provides a momentary output pulse at its cylinder port when pressure is applied to its inlet. No additional flow is possible until pressure at the inlet is removed, reset time is allowed, and pressure is reapplied. For your air press, it can be used to convert a start signal from a hand or foot control to a pulse signal. This only allows one cycle of the press circuit even if the operator holds the starting device on. The operator must release the starting device to reset the one- shot/pulse valve– and then re-actuate to achieve the next cycle. Order Model Number OS-1 Cut-away view of OS-1 12-1-99 Valves The unique design of the Super-Vee TM control results in superior adjustability from full flow to bubble-tight shut-off with an orifice that provides precise repetition of selected flow rates. Fine pitch threads raise and lower a straight stem needle with an angled “V” notch. The cross-sectional area of the “V” notch changes linearly as the stem moves through the control orifice– thus providing easier, less sensitive adjustability than is common to tapered needle type valves. For Air or Hydraulic service to 150 psi.
