3. Slowly open the hand valve in the control line and adjust the pilot setting if necessary. Set the monitoring regulator at a slightly higher control pressure than the working regulator.

4. Completely open the downstream block valve.

5. Slowly close the bypass valve, if any.

ShutdownInstallation arrangements 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 pilot or main valve. The following steps apply to the typical installation as indicated.

Single-Pilot, Dual-Pilot Regulator or wide-Open MonitorAs well as applying to a single-pilot regulator (Figure 3), the steps in this procedure are also valid for a dual-pilot regulator (Figure 4) or a wide-open monitoring installation (Figure 8) and just need to be repeated for each regulator in such an installation.

1. Slowly close the downstream block valve. If the control line is downstream of the block valve, also close the hand valve in the control line.

2. Slowly close the upstream block valve and the hand valve in the pilot supply line.

3. Slowly open the vent valve in the downstream pipeline. If the control line is downstream of the block valve, also open the vent valve in the control line. Permit all pressure to bleed out.

4. Slowly open the upstream pipeline vent valve. Allow all pressure to bleed out of both the piping and the pilot.

working Monitor 1. Slowly close the downstream block valve and the

hand valve in the downstream pressure control line.

2. Slowly close the upstream block valve and the hand valves in both pilot supply lines.

3. Slowly open all vent valves and permit all pressures to bleed out of the piping and regulators.

MaintenanceRegulator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement of parts depends upon the severity of service conditions or the requirements of local, state and federal regulations. Due to the care Emerson™ takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Emerson.

The stem O-rings (key 6, Figure 14) on the Type 1098 or 1098H actuator can be lubricated during regularly scheduled maintenance, using the grease fi tting (key 28, Figure 14). Stem O-rings can be checked for damage during normal operation by line pressure leakage or unexpected grease extrusion from the actuator vent (key 27, Figure 14). All O-rings, gaskets and seals should be lubricated with a good grade of general-purpose grease and installed gently rather than forced into position. Be certain that the nameplates

●작동원리▶1098EGR은 전단압력을 작동의 매개물로 삼는다.

전단압력은 Pilot를 통하여 감압되어 Actuator의 Diaphragm에 Loading(하중)을 준다.

후단압력은 Actuator에서 Loading압력에 역 작용하며 동시에 Pilot Spring의 힘+대기압력과 반대방향으로 작용(Two

Pass Control) 함으로서 응답속도가 빠르다.

▶후단압력이 설정압력보다 낮을 때

가스사용량이 증가하여 후단압력이 Pilot Spring의 설정압력보다 아래로 떨어지면 Pilot Diaphragm에 힘이 가해져 Pilot

Valve Plug는 열려 추가의 Loading압력을 보낸다. 이 압력은 Stem을 통하여 주 Regulator의 Valve Plug를 열고 후

단 측으로 필요한 유량을 공급하게 된다. Actuator Diaphragm에 과다한 압력이 가해지면 Bleed Orifice (Type 61

Series Pilot) 또는 Bleed Hole(Type 6351 Pilot) 또는 Restriction(Type 6352, 6353, 6354, Series Pilot)을 통하여

후단 쪽으로 빠져 나간다

▶후단압력이 설정압력보다 높을 때

후단의 요구가 충족되면 후단압력이 증가하게 되고 이 압력은 Pilot Diaphragm과 Actuator Diaphragm에 작용한다.

Pilot에 작용된 압력이 Pilot Spring의 설정치를 넘어서게 되면 Pilot Diaphragm을 움직여 Pilot Valve Plug를 닫으면

더 이상의 Loading 압력공급이 중단되며 Bleed Valve가 열리면서 Loading 압력의 감소가 일어나 주 Regulator의

Valve를 닫히게 한다.

▶Main Diaphragm을 보호하기 위하여 모든 Pilot들은 Relief Valve를 가지고 있어서 주 Regulator의 Diaphragm양단

의 차압이 Model 별로 약 1~1.7Bar일때 Loading압력은 Relief Valve를 통하여 Regulator의 후단으로 방출된다.
