LUBRICATION The use of lubricators upstream of valves is NOT recommended. Likewise, air containing compressor carry over lubricants requires cleaning with suitable filters upstream of the valve. Hydrocarbon oil, with its characteristic viscosity increase at low temperatures, may cause the valve to operate erratically or to fail to operate.

Supply and exhaust piping must be full area, unrestricted. ASCO flow controls and other similar components must be installed in the cylinder lines only. At temperatures below 3 F: 5 psi minimum mainline operating pressure differential when valve selection gasket is in external position and proper auxiliary air pressure is applied. See graph with dimensional drawings for auxiliary pressure vs. mainline pressure. Minimum 5 psi operating pressure differential when selection gasket is in the internal position.
