- The Bureau of Reclamation, Lower Colorado Region, Boulder City, NV, has a requirement for the repair of a sixty (60) inch VC Butterfly valve. All work shall be performed in accordance with the Bureau of Reclamation criteria, methods, and procedures and the general specifications contained in the Statement of Work. VC Butterfly Valve Repair - STATEMENT OF WORK - RFQ#07SQ303091 1. Work location: 1-1) The VC BFV is a Butterfly Valve installed in an adit beside the Lower Nevada Penstock at Hoover Dam. The dam is 5 miles east of Boulder City, Nevada. U. S. Highway 93 crosses the dam. 1-2) The valve is 60 inches in diameter and is used to route cool air originating in the penstock through an elevator shaft and ultimately to the visitor center at the top of the dam. 1-3) The valve, and all hydraulic controls for it, is mounted above a concrete walkway used by visitors as part of the normal tour. 1-4) A float switch used to operate the valve is located inside the penstock adit itself a short distance from the valve. 1-5) Electrical controls for the valve are located in a control panel along the walkway below the valve. 2. Agency work includes: 2-1) Providing 11 PDF drawings and 4 pictures depicting the valve and its associated equipment. 2-2) Provide access to the valve and the area around it for prospective bidders to examine the equipment and evaluate the extent of the work needed to complete the project. 2-3) Provide a Bureau of Reclamation inspector to authorize and monitor the vendor's work. 3. Vendor's work includes: 3-1) Drain and dispose of all hydraulic fluid from the system. 3-2) Before any device is disconnected, all wiring for the valve system is to be wire checked to note any discrepancies with the system schematics and wiring diagrams. 3-3) Rebuild the 6x39" hydraulic cylinder using all new seals. The cylinder is an Ortman Series"3TH" with a rod diameter of 2.50", and will require a Rod Gland Kit, a Rod Seal Kit, and a Tube Seal Kit. 3-4) Remove all control piping, conduit, two junction boxes, limit switches, pressure switches, pressure gauge, ball valves, flow control valves, oil reservoir, pump and motor, all 4 accumulators, and Pall filter assembly. 3-5) Remove all loose rust and scale on the entire length of the 60 inch exposed pipe in the adit, (approximately 18 feet), butterfly valve body and control framework, coat all surfaces with rust converting primer, and finish paint with 2 coats of two-part semi-gloss liquid beige epoxy. 3-6) All replacement hardware, (nuts, bolts, washers) with stainless steel. 3-7) All replacement components are, (if not of stainless steel construction), to be primered with a zinc ladened epoxy based primer and finished with 2 coats of two-part semi-gloss liquid beige epoxy. After installation, components are to be touched-up as needed to restore complete paint coverage. All components listed below by manufacturer are what are presently installed in the system. Equivalent parts by other manufacturers may be substituted PROVIDED that those parts meet the specifications of the presently installed parts. Replace all listed components of the existing system as follows: A) Replace all four 15 gallon accumulator tanks with 4 new accumulator tanks. The pre-charge for each accumulator is 850 pounds. (The existing accumulators are Oilair Model 15-100-2.) B) Replace the 4-way control valve. (The present valve is a Dynex/Rivett 6615-D05H-115/DF-10.) C) Replace the air bleed valve. (The present valve is a Vickers type ABT-03-10 air bleed.) D) Replace the filter assembly. (The unit is now a Pall filter assembly Model HH9800A12DNTBPT). E) Replace all tubing and tubing fittings (3/4 inch, 1/2 inch, and 1/4 inch) with stainless tubing (ASME 308 or 316) rated for 3000 psi or more. F) Replace all 3 Mercoid pressure switches with non-mercury type pressure switches made of stainless steel. The operating pressure range should be 200-2500 psi. Set the low pressure shutdown and lockout pressure switch (PS-1) to close at 1300 psi and open at 1375 psi. Set the pump operation pressure switch (PS-2) to close at 1400psi and open at 1500 psi. Set the hydraulic system high pressure shutdown and lockout switch (PS-3) to close at 1650 psi and open at 1550 psi. G) Replace one pressure gauge with a new gauge with a scale of 0-3000 psi, +/- 2 per cent accuracy, 6" diameter. The case must be stainless steel. H) Replace all manual shutoff valves and flow control valves with stainless replacements. Add 2 manual air bleed valves with tubing adequate to vent the system without spilling oil. I) Replace the hydraulic reservoir (including float switch) with an identically sized 40 gallon unit of stainless steel construction. (The present unit is a Vescor 10040.) J) Replace the hydraulic pump and motor with a new unit. (The existing motor is a Baldor Catalog #37BA4004 motor, (5 HP, TEFC, 460VAC, 3-phase, 60 HZ, 1200 RPM). The existing pump is a Vickers 20V-5A-1A-20-282.) K) Replace the pressure relief valve. (The existing valve is a Vickers type CS-03-C-50.) Set the valve to relieve at 1700 psi. L) Replace the suction filter on the hydraulic pump with a new filter assembly. (The existing filter assembly is a Vickers filter Number OF3-08-3RV-10.) M) Replace both electrical junction boxes with new 8" x 10" x 4" enclosures constructed of stainless steel and rated NEMA 4X), and replace all wiring between all new devices and equipment and the main control board.

All terminations are to be made using insulated ring lugs. N) Replace both valve position limit switches with new switches. (The new switch must be a sealed heavy-duty stainless switch such as a Honeywell HDLS. No switches containing mercury will be allowed. O) Replace the flood level switch in the penstock with another switch designed for this purpose and constructed of stainless steel. (The existing switch is a Magnetrol X53-4701-001.0.) No switch containing mercury will be allowed. P) Replace all flex hoses. The replacements must be rated for 3000 psi or more. Q) Replace all conduit on the valve with fiberglass conduit.
