What they do is to keep a small amount of pressure in the line so the shoes can not retract all the way back from the pressure of the brake return springs. 4 North America version ESM 45-ESM 50 Technical Data 60Hz North America ESM 45 ESM 50 Nominal pressure psi g Maximum working pressure psi g Minimum working pressure psi g Ambient temperature - min / max °F 34113 FAD at nominal pressure 278. Ensure that all valves on the CP-24 are closed (Figure 1 and Figure B1). Pressure: 2 psi. 25-1 General. With drum brakes, a ten pound valve is used to compensate for return spring tension and maintain wheel cylinder sealing in the drums. Do not attempt to adjust the pressure relief valve. It falls within Category 4 for Group 2 Gases. This residual pressure valve is 10 PSI for drum brake systems to compensate for return spring tension and maintain wheel cylinder sealing in the drums. While I am still unclear how or why the function of this 2 PSI check valve would differ depending on the PSI pressure level in the oil line, I concluded that this valve is probably not the cause of my smoking problem if it were in fact malfunctioning (i. My plan was to remove the stock drum residual valve from the master cylinder and use the inline valve, but I just realized something:1. Record total flow gpm. Install an in-line shutoff valve to allow immediate control over the air supply in an emergency, even if a hose is ruptured. drums with just one push on the pedal. The low pressure switch shall supervise pressure in the system and shall be set to activate at 70 kPa (10 psi) above the dry-pipe valve trip point pressure. Service Slip Tee, one 1/2 in. Opening the valve adds the WUR into the circuit which has an outlet into the return line.
