T ype 99 2 1. The pressure/temperature limits in this Instruction manual and any applicable standard or code limitation should not be exceeded. 2. For stability or overpressure protection, a pilot supply regulator may be installed in the pilot supply tubing between the main valve and pilot. 3. T ype 61LD construction has narrower proportional band [...]

Since loading pressure needs to exceed outlet pressure only moderately to stroke the main valve fully open, a continued increase in [...]

T ype 99 5 The monitoring pilot should be upstream of the working monitor regulator . This enables a closer setpoint between the working regulator and the monitoring pilot. Special T ypes 161A YW and 627-109 monitoring pilots with quick-bleed operation have been designed to give faster response to abnormal downstream conditions. T able 4 gives the [...]

Clean out all pipelines before installation and check to be sure the regulator has not been damaged or collected foreign material during shipping.

T ype 99 8 this recommendation due to the pipe arrangement, it may be better to make the control line tap nearer the regulator outlet rather than downstream of a block valve. Do not make the tap near any elbow , swage, or nipple which might cause turbulence. In many instances, it will be necessary to enlarge the downstream piping to keep ow velo[...]
