6. Bulletin 71 4 630R December 2011 Type 630R Relief Valve Figure 1 Type 630R Relief Valve Introduction The Type 630R is a general relief valve that is low pressure units have larger diaphragm area available in NPS 1 and 2 DN 25 and 50 body sizes to provide more accurate control of low pressure It is frequently used at compressor stations refineries settings while the high pressure units can withstand and similar plants requiring a backpressure gas inlet pressure up to 550 psig 37 9 bar and can regulator for relief pressure settings up to 250 psig control pressures up to 250 psig 17 2 bar 17 2 bar Interchangeability The Type 630R relief valve can be easily converted in the field to a Type 630 Features regulator by reversing the actuator and using a new valve carrier disk and orifice Tight Shutoff Provided by an O ring seat n Sour Gas Service Capability Optional materials e Easy Maintenance The inlet adaptor acts as are available for applications handling sour union nut enabling speedy inspection of trim parts gases These constructions comply with the Ease of Use The Type 630R is available in both recommendations of NACE International Standards high pressure and low pressure constructions the 0175 and MRO103 4 FISHER EMERSON Process Management D100158X012 Bulletin 71 4 630R Specifications Regulator Construction Low Pressure High Pressure Body Sizes NPS 1 and 2 DN
7. aphragm protector 1 The pressure temperature in this Bulletin and any applicable standard or code limitation should not be exceeded Principle of Operation Refer to Figure 2 Inlet pressure registers beneath the diaphragm As long as the inlet pressure is less than the set pressure spring force causes the lever to hold the valve closed When the inlet pressure exceeds the set pressure the diaphragm moves to compress the spring and the lever opens the valve allowing inlet pressure to bleed into the downstream line or to atmosphere until the inlet pressure returns to Set pressure Installation The Type 630R relief valve may be installed in any position However the outlet connection and vents must be protected against the entrance of rain snow insects or any other foreign material that may plug the outlet or affect the opening and closing of the valve If itis necessary to pipe away the outlet remove the outlet screen if one is present Flow through the valve must be as indicated by the flow direction arrow on the body For dimensional information see Figure 3 Fisher provides an instruction manual with every valves shipped Refer to this for complete installation operation and maintenance instructions Included is a complete listing of individual parts and recommended spare parts 18 Bulletin 71 4 630
