DTR-Line Relieving ield Repairable/Interchangeable Parts DuraSeal parts are completely interchangeable with the original 800 Series General Valve Twin Seal double block and bleed plug valve. DuraSeal components manufactured from superior materials can upgrade existing TwinSeals in the field. The DuraSeal can be repaired inline after depressurizing and draining the valve without special tools. Simply remove the valve s lower plate or bonnet and replace the slip/seal assemblies from top or bottom of the valve. 1 ully opened the port allows passage of the product while protecting the slip seal elastomer n improved valve with a proven history We took an alternative path. Unlike many valve manufacturers who often strip valves in their quest to reduce manufacturing costs, we have taken a proven double block and bleed plug valve and improved its design. With the new DuraSeal, you get the proven advantages of a valve that has been considered the standard of quality since To improve the valve s integrity, we have incorporated a superior slip design and more durable body. To improve performance and longevity, we have incorporated a more reliable stem seal design. In short, the new ranklin DuraSeal is made to last - not to make a quick sale. Reliable double protection mechanical seal The ranklin DuraSeal plug valve seals mechanically. During rotation of the plug there is no abrasion or wear between the sealing surfaces. When the slips reach the closed position they expand firmly into the valve body creating a primary elastomeric and secondary metal-tometal backup seal. The DuraSeal does not require sealant under any circumstance to seal. ast Low Torque Operation The DuraSeal can be easily automated using hydraulic or pneumatic or electric actuators. Torque requirements are low. In smaller sizes only two and one quarter turns can fully open or close the valve fter quarter turn, both slips are positioned in the flow to begin seating mode In the closed position the elliptical seats are firmly seated into the valve body creating a primary and secondary fire safe seal t this point double block and bleed can be safely and easily performed

4 Operation / pplications VLVE OPERTION Opening the Valve: Turn the hand-wheel counter clockwise. During this operation the plug is raised while the slips are retracted away from the body. When the slips are fully retracted from the body seating area, the plug is then able to rotate 90 degrees to the fully open position. When the valve is in the full open position, the slips and slip seals are completely protected from line flow. losing the Valve: Turn the hand-wheel clockwise. During this operation the retracted plug and slips are rotated 90 degrees without body contact. This rotation continues until the slips are positioned over the upstream and downstream port areas. ontinued rotation of hand-wheel mechanically forces the plug downward and forces the slips outward to seal firmly against the valve body. This produces a secondary metal to metal seal on both upstream and downstream areas providing double isolation. PPLITION NOTES iofuels Product Isolation: Secure sealing of iofuels is critical in protecting the environment. The Duraseal D with its verifiable secure shutoff is perfect when process must be contained. Multi-Product Manifolds: Some pipeline manifolds need to flow various products (e.g. diesel, jet fuel, gasoline, etc.) reliably and without contaminating one another. This DURSEL D Valve is used to provide positive shut off and zero leakage to prevent cross contamination. Prover Loops: In prover loops, the calibration of flow meters requires that every valve in the system must have zero leak rates. ny leak could mean an error in calibration. The DURSEL D Valve is used to ensure that when the valves in the system are closed, they are leak tight. ustody Transfer Units: Transfer of valuable media relies on accurate measurement of product. The DURSEL D provides secure tight shutoff ensuring that the transfer is accurate. Terminals: Loading and unloading tanker vessels requires positive sealing in order to prevent spillage into the water. The DURSEL D provides such positive sealing and is the most reliable in the market. Tank arms (Oil Depots): Valves used for tank isolation needs to work reliably with zero leak rate. These valves are also operated frequently. The DURSEL D valves provide a reliable long term high integrity seal designed for frequent use with verifiable zero leak. viation ueling Systems: uel hydrants at airports need to allow for quick maintenance, repair, leak locating and testing. This requires a valve that can close quickly and positively seal off the relevant sections. The DURSEL D Valve s variable zero leak rate ensures that maintenance, repair, leak locating and hydrant testing can be done quickly and safely. Import/Export acilities. Offshore Platforms: Secure shutoff is imperative on an offshore platform in that leakage can result in contamination of the water and possible equipment damage. The DURSEL D is the best choice for low pressure positive shutoff. lending Units: The accurate blending of high grade fuels requires valves of high sealing integrity to insure accurate addition of additives in blending operations. 4

6 Preferred Mounting Positions for DuraSeal Valve 1.0 SOPE O INSTRUTION 1.1 This information is provided for support of the Duraseal Valve in maintaining the maximum life and function of the valve. 1.2 The contained information is subject to change without notice. 1.3 This document provides information for typical installations. In the event of unique situations, please contact your representative or the factory. 2.0 DEINITIONS 2.1 D - Double lock and leed, method to test seat integrity with valve closed while under pressure. 2.2 DI-1 - Double Isolation and leed, i-directional seating. PI 6D definition of redundant sealing surfaces in both flow directions. 2.3 DTR - Differential Thermal Relief, provides the cavity relief functions of PI 6D. lso contains D bleed function. 3.0 ONSIDERTIONS 3.1 Positioning of valve to provide operational access in installation. This is of particular concern for manually operated valves in pipe racks. Operator and handwheel extensions are available to improve access. See PU-002-EN for details on the extension of DTR systems. 3.2 Positioning of DTR to provide proper function. The DTR relief direction should be toward the pressure side to be isolated. In a typical piping system, there is often a specific direction. When isolating equipment such as pumps, the preferred isolation may be different from the prevailing flow direction. See PU-002-EN for DTR details. 3.3 Positioning of bleeds and drains to provide adequate operation. On valves which require complete draining, ensure that drains are positioned to provide complete draining. On valves which require D operation, it is typically preferable to position bleed valves for an elevated position so that D bleeds the minimum amount of liquid. 3.4 Positioning for reducing damage due to solids contained in fluids. With solids in the fluids it is preferable to have regular draining of the body cavity to reduce accumulation and reduction of performance. It is also preferable to have the DTR to the upper side so that solids do not damage the DTR checks or valves. 4.0 PREERRED MOUNTING POSITIONS Positioning of the stem in the vertical position or with the stem above horizontal is acceptable. User must take drain and bleed issues into consideration If the valve is oriented with the stem in the horizontal position, it is preferable that the left flange is receiving the prevailing flow and that the DTR is on the upper side. This provides an inlet flow upon opening that tends to flush out any accumulated solids Mounting of the valve with the waterway oriented vertically is acceptable. This provides an inherent cavity flushing characteristic in both the upward and downward flow directions Mounting the valve with the stem facing down is non-preferred, but may be acceptable for very clean conditions. This exposes the stem and stem seals to potential damage from settling solids and exposes the DTR to potential accumulations. 6

16 DTR Operation The Duraseal valve is by design a bidirectional DI-1 valve: This design has inherent characteristics of trapping body cavity pressure. ecause valves in liquid or condensing service can have a thermal hydraulic expansion within the trapped cavity, PI 6D requires a cavity pressure relief system. The valves on the configurations permit different directionality characteristics. These configurations relate to the operational reliefs and D operation. The lower body bleeds are not addressed in this document, but should be used as necessary to eliminate line solids from accumulating under the plug. or the following configurations, the left flange (when facing the piping of an upright valve) is the upstream flange. or installations with clearance issues, a reverse DTR may be ordered which provides the right flange as the upstream flange. The upstream flange is the flange of preferred pressure isolation. Depending upon the required isolation, the valve preferred pressure direction may not be the direction of flow. or applications where a piece of equipment is being isolated from the piping, the preferred pressure isolation will typically be the flange away from the equipment. Extending of the ody leed Outlets: or convenient bleed positions, the body bleed outlets may be extended from the NPT outlet of the manual bleed valve.
