PART 2 – PRODUCTS

2.1 OPERATING REQUIREMENTS
A. Performance: Each valve shall be designed and guaranteed by the sleeve valve manufacturer to operate in a clean/raw water environment throughout its required performance range without excessive vibration, noise levels, or cavitation damage, for the conditions stated in Table 1.

B. Valve Operation: In the closed position, the sliding sleeve gate shall be fully advanced in the upstream direction with its sealing surface against the inlet seat sealing ring. In the fully-open position the sliding sleeve gate shall be fully retracted in the downstream direction to release water through the valve internal fixed sleeve nozzles. The advance and retract strokes of the sleeve gate shall be driven by an actuator coupled to an appropriate drive train system and mechanisms utilizing two operating screws or internal/external drive levers for flow control.


2.2 EQUIPMENT REQUIREMENTS
A. Valve Assembly Components: Each in-line sleeve valve assembly shall consist essentially of the following. An inlet and outlet flanged body for mounting the valve into the pipe system. Internal to the valve body shall be a fixed cylindrical sleeve with an upstream contoured head to divert the water flow into the outer annular chamber formed between the internal fixed sleeve and the body. The internal fixed cylindrical sleeve shall utilize tapered control nozzles in a multiple opposing spiral pattern having the nozzle larger end diameter at the outside diameter of the fixed sleeve. A sliding cylindrical sleeve gate fitted around the fixed sleeve shall control fluid flow and pressure based on its position by exposing fixed sleeve nozzles thus allowing flow from the outer annular chamber to the inner fixed sleeve chamber of the valve. The sliding sleeve gate in its fully closed position shall provide shutoff with its leading edge making contact on a resilient seat seal retained at the upstream end of the fixed sleeve.
B. The nozzles shall have a flow coefficient of at least 0.94. The number, size, spacing, and over all valve stroke length for the nozzles shall be determined by the valve manufacture based on the application and be proportional to the sleeve dia. while providing superior flow control over the entire range of required performance.
C. The resilient seat seal on the fixed sleeve must be easily replaceable through the inlet body inspection ports without removing the valve from the pipe line.
D. The fixed sleeve must have a contoured upstream dome to minimize turbulent flow.
E. The sliding Sleeve Gate shall include a downstream replaceable seal without removing the valve from the pipe line.
F. Flanges shall conform to AWWA C207. The Class shall be per design pressure.
G. A minimum of 2 properly sized inspection ports shall be provided in the body for valve inspection, maintenance and seat replacement.
H. For manual operation the valve shall be equipped with mechanical stops to limit gate travel in both the full open and closed positions.
I. Valve Manufacturers: Henry Pratt Company Model 711 or Engineer Pre-Approved Equal

2.3 SLEEVE VALVE ACTUATOR REQUIREMENTS
A. The Sleeve valve shall be provided with a modulating control type electric actuator utilizing a 4-20ma signal input and position feedback. A mechanical dial position indicator or equal shall be integral to the actuator in addition to requirements in the specified actuator section.
B. The actuator shall be sized to deliver a minimum of 4 times the force necessary to overcome peak dynamic and static fluid and frictional forces.
C. Operating time shall not be less than 300 seconds.

2.4 SLEEVE VALVE MATERIAL REQUIREMENT
A. Assembly components shall be manufactured from the following materials:
1. Valve Body: Carbon steel Plate: ASTM A-516 Grade 70
Pipe: ASTM A-53 Grade B, A-106 Grade B
2. Fixed Sleeve: Stainless Steel ASTM A-240 Type 304

4. Drive Screws: Stainless Steel ASTM A-276 Type 304
5. Seat Retainer: UHMW or Stn.Stl. ASTM D-4020 or ASTM A-240 Type 304
6. Gate Seal Retainer: Stainless Steel ASTM A-240 Type 304
7. Sleeve Seat: Resilient Rubber Buna N
8. Gate Seal: Resilient Rubber Buna N
9. Packing: ”V”Type or PolyPak® Nitrile or equal
10. Bearings: Bronze ASTM B-584 C93200 or equal
11. Drive Nuts: Bronze ASTM B-271 C95400 or equal
12. Fasteners: All internal studs, bolts, washers, nuts, etc. in contact with water shall be stainless steel Type 304.

PART 3 - EXECUTION

3.1 INSTALLATION
A. Valve installation shall be in strict accordance with the manufacturer’s printed recommendations, and the Contract Documents.
B. Valve supports shall be installed by the contractor at appropriate positions as indicated on the submittal drawings.
C. All gaskets, bolts, nuts, etc. and installation equipment required for installation of the valve into the piping system is by others.

3.2 FLOW CONTROL VALVE PERFORMANCE TESTING
A. The CONTRACTOR, assisted by the valve manufacturer’s authorized representative, shall test each flow control valve over the indicated flow range. For each test condition, the flow shall be recorded along with the inlet and outlet head conditions, corrected to the elevation of the centerline of the valve. Full stoke time for opening and closing shall be recorded.
B. Flow rates, duration, and dates for testing will be determined by the CONSTRUCTION MANAGER and or the PROJECT ENGINEER.
