JRHL Series. Pressure Reducing Valves for Low Flow and Low Pressure Process Gas GAS PRESSURE REDUCING VALVE. Features

Transcription

1 JRHL Series Pressure Reducing Valves for Low Flow and Low Pressure Process Gas GAS PRESSURE REDUCING VALVE The JRHL Series line of low flow pressure regulators have the ability to handle low set pressures and very low flows with less offset than valves with smaller diaphragms. The durable valve body and metal trim components are machined from ASTMA479 36L SST barstock. The valve is outfitted with the rugged Jorlon diaphragm and Teflon, PEEK or EPDM seats for ANSI Class VI shutoff. Features In-line removable seat and trim facilitates in-line cleaning and maintenance Barstock construction guarantees material integrity and quality surface finish Two Cv offerings of.8 and. and four spring ranges guarantees a valve that will fit your application Optimized internal volume Proprietary Jorlon diaphragm material provides exceptionally long life Soft seat material for ANSI Class VI shutoff Can be used on continuous clean steam, and on non-cavitating fluids Applications Ideal for production facilities and equipment which require gas flow regulation.

It features a /8" FNPT port located on the spring housing. The user can easily tube this vent to a safe location. This option can be incorporated into a selfrelieving regulator that provides an additional port to permit the safe expulsion of hazardous media. Panel Mount The panel mount feature utilizes a threaded spring housing and a panel mount ring to secure the regulator to an instrument panel. This option requires a -/" panel cut out. Self Relieving The self relieving option is used for internal venting of downstream pressure. From a practical standpoint, it allows for immediate reduction in pressure setpoints and automatically alleviates regulator lock up. Tamper Proof The tamper proof option replaces the standard adjusting knob with a stainless steel acorn nut. Lockout Device The lockout device is a piece polypropylene enclosure which encapsulates the adjustment knob and prevents unwanted set point changes. The part number required for this valve is 697.

5 SIZING SIZING All of the following sizing charts for the JRHL were derived using Nitrogen as the flow medium at ambient conditions. In order to convert your gas to the equivalent volume of Nitrogen, multiply your application s flow by the appropriate multiplying factor. GAS Specific Gravity Multiplying Factor Air. Ammonia Argon Arsine CO.967 CO.9.6 Ethylene.97 GAS Specific Gravity Multiplying Factor Helium Hydrogen.7 Methane..76 Natural Gas..76 Nitrogen.967 Oxygen..7 Propane.49.7 For all other gaseous media, use the following formula to calculate the appropriate multiplying factor. (Sg = Specific Gravity of the media) Cv Trim Selection Instructions. Select a graph on the following sixteen pages that best represents your outlet pressure set point and flow range.. Select the inlet pressure line on the graph (horizontal sloped line, P) that reflects your application's actual inlet pressure. 3. That line indicates the Pressure/Flow capabilities of the Cv trim under flowing conditions --
