RegO ® Globe & Angle Valves Vent Valves Especially designed to bleed off liquid or vapor pressures trapped in transfer lines. When installed in the downstream boss of RegO ® globe and angle valves used at the end of a liquid transfer hose, the bleeder valve allows for the controlled venting of the product and indicates to the operator that the valves are closed and he can disconnect the coupling. They may also be used as a fixed liquid level gauge where the dip tube is part of the container. Accessories Part Number Service Connection Actuation 3165C 3165S TSS3169 LP-Gas Only LP-Gas & NH 3 1 ⁄4" M. NPT Knurled Slotted Tee Handle Warning Plate Kit 2550-40P 3165C with 2550-40P 3165S TSS3169 Combination Valve for Bulk Storage Containers Designed for installation on bulk storage containers, this valve combines a pressure gauge mounting and provision for a fixed tube liquid level gauge. The shut-off valve prevents the pressure gauge from being subjected to constant pressure, thereby prolonging its life and accuracy. The valve may be closed, and the vent valve opened to vent pressure from the gauge to permit replacement. For fixed liquid level gauging, the valve can be mounted at the maximum permitted filling level. When equipped with a dip tube threaded 1 ⁄8" M.NPT, it can be installed at any convenient level. Part Number A2805C Container Connection 3 ⁄4" M. NPT * Has 1 ⁄8" F. NPT opening for installing separate dip tube. Service Connection 1 ⁄4" F. NPT for Gauge Mounting Liquid Level Vent Knurled* Fixed Liquid Level Gauges Especially designed to provide a visible warning when containers are filled to the maximum permitted filling level. At the start of the filling operation, with the vent stem opened, the valve discharges vapor. When the maximum permitted filling level is reached, the valve discharges liquid. These valves are normally furnished with a 12", 3 ⁄16" O.D. dip tube and incorporate a No. 54 drill size orifice. An optional instruction plate with “Stop Filling When Liquid Appears’’ may be ordered for use with these valves.

RegO ® Excess Flow, Check, Filler, & Vapor Equalizing Valves LP-Gas Excess Flow Valves Safety Warning Purpose In its continuing quest for safety, Engineered Controls International, Inc. publishes a series of bulletins explaining the hazards associated with the use, misuse, and aging of LP-Gas valves and regulators. It is hoped that these factual bulletins will make clear to LP-Gas dealer managers and service personnel, that the utmost care and attention must be used in the installation, inspection, and maintenance of these products, or problems could occur which would result in injuries and property damage. The National Fire Protection Association Pamphlet #58, “Storage and Handling Of Liquefied Petroleum Gases” states in Section 1-6 that “In the interest of safety, all persons employed in handling LP-Gases shall be trained in proper handling and operating procedures.” These “ECII ® Safety Warnings” may be useful in training new employees and reminding older employees of hazards that can occur. It is recommended that all employees be furnished with a copy of NPGA Safety Pamphlet 306-88 “LP-Gas Regulator and Valve Inspection and Maintenance.” Nature of Warnings It is recognized that warnings should be as brief as possible, but the factors involved in excess flow valve failures to perform are not simple. They need to be fully understood. If there is a simple warning, it would be: 2. The break or damage to the downstream line is not large enough to allow enough flow to close the valve. Make sure that the excess flow valve really closes when the flow exceeds normal transfer flow. This bulletin is not intended to be an exhaustive treatment of excess flow valves, and certainly does not cover all safety practices that should be followed in installation, operation and maintenance of LP-Gas systems which include excess flow valves. Selection and Installation The selection of a given closing rating of an excess flow valve involves an analysis of the complete piping system and is beyond the scope of this bulletin. 3. A shut-off valve in the line is only partially open and will not allow enough flow to close the excess flow valve. It is sufficient to say that an excess flow valve must be installed in the correct direction and will close only if the flow of liquid or vapor exceeds its designed closing rating. Many valves have been installed with closing ratings considerably higher than any flow that could be obtained by a downstream rupture in piping or hoses and thus give none of the protection for which they are intended. Engineered Controls International, Inc. provides excess flow valves with a number of closing ratings. Engineered Controls International, Inc. obviously can take no responsibility for the proper selection or correct installation of any valve. Excess flow valves do not provide complete shut-off because there is a bleed at the check to permit pressure equalization. Causes of Failure to Close Installers, LP-Gas plant managers and service personnel should be aware that the excess flow valves may not close if these conditions are present. 1. The piping system restrictions (due to pipe length, branches, reduction in pipe size or number of other valves) decrease the flow rate to less than the valve’s closing flow. 4. LP-Gas pressure upstream of the excess flow valve, particularly due to low temperature, is not high enough to produce a closing flow rate. 5. Foreign matter (such as welding slag, scale or sludge) is lodged in the valve and prevents closing. 57
