Common methods of external overpressure protection include relief valves, monitoring regulators, shut-off devices and series regulation.

CP400 Series Regulators Subjected to Heavy Snow Conditions Installation with External Overpressure Protection Some installations, such as in areas with heavy snowfall, may require a hood or enclosure to protect the regulator from snow load and vent freeze over. If the regulator is used in conjunction with a Type 289H relief valve, it should be installed as shown in Figure 5. The outside end of the vent line should be protected with a rainproof assembly. The Type 289H is typically set 10 inches w.c.

CP400 Series instruction manual for Type VSX4 Slam shut for adjustment and maintenance of the slam shut. The range of allowable pressure settings for the primary regulator is stamped on the nameplate. If the required setting is not within this range, substitute the correct spring (as shown in Table 5). If the spring is changed, change the nameplate to indicate the new pressure range. A pressure gauge should always be used to monitor downstream pressure while adjustments are being made.

CP400 Series Step 4: • Once the operator feels the click of the re-latch occurring, the reset button (key 30) should be pushed completely back into its original position. Shutdown Installation arrangements may vary, but in any installation it is important that the valves be opened or closed slowly and that the outlet pressure be vented before venting inlet pressure to prevent damage caused by reverse pressurization of the regulator. The steps below apply to the typical installation as indicated. 1.

CP400 Series To Replace Valve Disk and Orifice 1. Remove the tubing connector (key 29, Figure 8) from the regulator body (key 70, Figure 8). 2. Remove the two cap screws (key 71) which hold the union ring (key 17) portion of the lower casing to the body. 3. The regulator can be removed from the body, exposing the disk (key 36) and the orifice (key 25). 4. Examine the seating surface of the disk.
