Products

1. Flanged End

• RFL flanged end SPV comes with Raised face, Flat face, Small Groove, Large groove, Ring Type Joint Flanges as option.
• SPVs are flanged as per ASME B 16.5; BS 10 Table ‘D’, ‘E’ & ‘F’;

• Raised Face – Allows use of wide combination of gasket designs and commonly used in process plant application. The main purpose of RF flanges is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint.

• Flat Face – The gasket surface and bolting circle face are on the same plane. Hence the whole face of the two flanges ensure full contact.

• Ring Type Joint – They are predominantly used in high pressure and high temperature service. The flanges provide metal to metal sealing when the metal ring is compressed between the flanges using bolts to create a tight contact between the grooves.

• Tongue and Groove – Here the flanges must be matched. One flange face has a tongue, raised face while the groove i.e the mating flange has a matching depression machined on to its face. Tongue and Groove facings are standardized in both large and small types.

2. Screwed End

• Threaded connections provide a streamlined and compact connection between the pipe and valve.
• The valve generally has a female threaded end connection in which the male threaded pipe fits.
• The end provides tapered or straight pipe threads.

3. Socket weld

• A socket is provided in the valve ends in which pipe is Inserted into the socket and welded. They are normally Used for small pipeline

4. Butt weld

• The pipe end and valve end are in equal diameter, The valve end is beveled to match with the thickness And bevel on the pipe and the two ends are butted to the pipeline and welded

1. Bare Stem

Valve supplied in open stem condition without any operating equipment.

This will reduce the cost and time of operation changes in on plant.

2. Wrench Operated

Sleeved plug valves are operated in Quarter turn. Hence for low torque applications a wrench provided for valve operation.

3. Gear Operated

For High torque applications Gearbox with hand wheel is provided to Operate the Valve.

4. Actuator Operated

For automation control of valves RFL can offer actuator operated valves, which can be Electric, Pneumatic or Hydraulic operated.

Quick closing spring return actuators are also offered.

5. Deadman Handle Operated

These are also known as spring return handle valves. The special handle ensures that the valve will always “spring return” to its original starting position, when hand / manual effort is released.
This type of valve finds vast application in critical service were the valve has to be quickly returned to the original position once a manual operation is completed. These valves assure safety and avoid unnecessary wastage, of costly medium, whenever the valve is allowed to remain in partially opened or closed position, inadvertently.

6. Extended Stem operated

Extended stem into “RFL can supply valves with extended stem. These valves are predominantly used in places where the valves are not in close proximity with the operator eg: valve located under water, toxic environment, hot pipe line”

4. Full Bore

Full Bore Valve they have a bore which is fully circular throughout the valve, including the obturator port. In pipeline fluid transportation, accumulation of dirt and foreign particles can lead to clogging and fluid contamination, especially in oil and gas industry, crude oil pipelines. This calls for PIGGING- Pipeline Inspection and Gauging.

5. Inverted/Pressure Balanced Type

The Inverted Sleeved Plug Valves completely eliminates the jamming Possibility of Plug with Valve body sleeves. The self-weight of the plug would provide always a dis engagement tendency, which is ably countered by an adjustable and supporting screw at the bottom.

1. Fire safe – API 607 / API 6FA / ISO 10497

RFL’s fire tested sleeved plug valves are in accordance with API 607 / API 6FA / ISO 10497 standard. These valves have an additional sealing feature to prevent leakage after the PTFE sleeve and other soft sealing parts are totally destroyed by fire.

2. Vacuum Service – Hood method

Vacuum test is conducted according t o A S M E Section V, Article 10, Mandatory appendix -IX which calls for helium mass spectrometer test, using Hood method. This test establishes the capability of sleeved plug valves to withstand helium leak under vacuum condition.

3. Fugitive Emission – API 641 / ISO 15848 – RFL Enviro

RFL’s low (Fugitive) emission valves comply with API 641 or ISO 15848. Valves are type tested with Methane with type tests procedures fully complying with API 641 standard requirements. Valves are also type tested with Helium with type tests procedures fully complying with ISO 15848 standard. Type testing to API 641 was successfully done in the renowned YARMOUTH RESEARCH LABORATORY, USA.

Jacketed valves are mainly used in applications where the process temperature should be maintained in the valve to keep the process media as fluid and to maintain the flow. To facilitate this process jackets are provided through which hot liquids/gases are circulated.

RFL’s jacketed valves are broadly classified in to two types,

a. Partially jacketed

b. Fully jacketed
