Design, manufacture and Supply for Dorot Make(Model :RE-EL, 100 Series) or any other IS Approved make Surge Anticipating valve Including flanges, Rubber packings, Bolts and Nuts, Etc complete with all lead and lift as directed by the Engineer in charge. Automatic, pilot controlled weir pattern hydraulic control valve, activated by the pressure of the pipeline. The valve is installed on a tee junction on the discharge manifold or the main pipeline, downstream the check valves of pumping station. The direct sealing diaphragm valve opens instantly, within less than a second, when loss of electric power is sensed at the battery- operated control panel of the RE/EL valve. The control panel energizes a solenoid valve, which opens the main valve. The valve stays in “opened” position until the returning flow arrives to the station, and will be sized to allow draining of part of it, so the velocity change of the returning flow, when stopped by the already-closed check valves, will not generate excessive transient pressures. Then the control valve starts closing by the command of a timing relay which stops the electric power to the solenoid. The valve closes gradually at an adjustable pace. In case of too-fast closure, that may cause pressure surge, the valve will function as a relief valve, re-opening slightly to increase the released flow rate- thus preventing over-pressure in the pump site. The high-pressure opening function is controlled by a hydro-mechanical pilot valve, adjustable by the operator. A drain pipe should be assembled to the outlet of the RE valve, to transport the drained water back to the pumps suction pit or to another location, where the high-velocity flow will not cause flood damage. The drainage pipe should be sized to avoid excessive velocity, that will create too-high hydraulic resistance and excessive side-stress in elbows. In most cases, the drainage pipe is larger than the control valve. An isolating manual valve must be installed upstream the RE valve, allowing maintenance when needed. The activation water of the control valve, including a filter that guarantees clog-free operation of the solenoid and the pilot, should be assembled upstream the isolating valve Specification: Main Valve - The valve shall be hydraulically operated, single chamber, direct diaphragm-sealing valve. - The valve shall consist of three major components: the body, cover and the diaphragm. - In Weir Patten valves, a diaphragm and a spring are the only moving parts, and the diaphragm itself is the component that closes or opens the liquid flow. Control chamber must have spring which enables closing of valve at low pressures. - The diaphragm shall form a sealed chamber in the upper portion of the valve, separating operating pressure from line pressure. - Packing glands and/or stuffing boxes are not permitted and there shall be no o-ring or similar seals on the shafts that may suffer friction which can start internal leakage in the valve. - The valves should be capable of regulating at very low flow, No hourglass-shaped disc retainers shall be permitted and no V-type, U-type or other slotted type disc guides shall be used. - The valve shall contain a resilient, nylon reinforced rubber diaphragm. - The ratio between valve flow capacity (KV) and the valve position shall be linear so to allow stable regulation even under high pressure differentials and low-flow conditions. - Disassembly and reassembly of all the valve's components shall be made possible on site, without having to remove the valve from the line. - Valves at sizes 20mm to 250mm have a single control chamber and diaphragm, sizes 300mm and 400mm are assembies of 2 control chambers and diaphragms, sizes 500 and 600mm are assemblies of 4 chambers and diaphragms, all actuated simultaneously by a common control circuit- as determined by the required control function. Each valve should be hydrostatically tested at least 60% above the rated pressure. A test report should be supplied with each valve.

Supply and delivery to work site, loading , unloading , stacking and fixing of Dorot make(Model: DAV-MH-KA) or any other Board approved make High combination Kinetic Automatic Temper proof air valve, Design Features: Combination air valve that incorporates the Kinetic and Automatic orifices as an integral unit in a closed housing, protecting it against accidental or deliberate damage. Standard, integral flanged connection. It should be a simple design with minimal parts for operation and maintenance At no point the flow section area is less than 100% of the nominal diameter. The flow passage must be Streamlined, unobstructed. Floats made of naturally-buoyant material (specific weight lower than water). Air-filled bodies that may crash or deform under pressure are not allowed. Floating is additionally- supported by open air-traps within the main float. Only the top float is subjected to pressure differential. It is a solid robust item, tested at 150% of rated valve pressure. Hydraulic sealing of main orifice provides drip-tight closure at very low pipeline pressure. A solid back-up of the main orifice seal, on the orifice flange, provides a mechanical stop to the top float following high-pressure stress of the resilient seal. Thus, resilient seal is operating within its elastic memory zone. The floats, shaped as buoyant cylinders, centrally- guided, top and bottom, by stainless steel 304 shafts, which are not located in air flow area. The top float is connected to the main float in such a way, that the distance between the two may vary by a few mm. The gap is used to open the small orifice, when the main float is losing it's buoyancy due to low water level. A very wide, resilient, smooth flat face seal ensures drip-tight sealing at very low pipe pressure. The cross-section area of the small orifice in the top float is calculated to ensure separation of the floats, even at high pressures, when the main float is losing its buoyancy. The small orifice is made of SST316 and has a ‘self-cleaning effect’ design, ensuring that the small orifice is not clogged by small particles. Its narrow passage is very short and enlarged to a bigger diameter immediately. Under pressure, this causes an air jet that removes any debris and dirt. No plastic small orifice is permitted as it may wear out by the high flow velocities. In case of requested service, all parts can be replaced conveniently by unskilled personnel using ordinary tools. A shield disc at the bottom, having a larger diameter than the float cylinder, provides protection against premature closing due to a high outflow of the air. The cover of the valve and the seal flange are shaped in a way that any "blow up" of water during valve closure is diverted sideways. The cover design of the standard valve enables the attachment of a "Surge Arresting" device as an additional option. This can be done at the site, without having to replace or temporarily remove the valve from the line. Valve body can contain, on request, two 1/4" tapped inspection ports, above and below the float. The valve body is coated by electro statically-applied, oven- baked Polyester coating. Fusion- bonded Epoxy and other coatings are available on request. The valve should be approved for operation in potable water system by an internationally recognized regulator (WRAS, NSF) The valve should be approved for operation in potable water system by an internationally recognized regulator (WRAS, NSF) MOC : Body: Ductile iron to ASTM A536, Bonnet/Cover: Ductile iron to ASTM A536, Float: Food- grade HDPE, Gasket and Seal: EPDM rubber, Lead screw: Stainless Steel (ASTM A194 Grade 304/AISI 304), Surface Protection: Standard: Polyester coating min.100microns, color RAL 5005 Blue, Optional: Epoxy coating min. 150 microns, color RAL 5005 Blue, Both are baked at 300deg.C. etc., complete with all lead and lift as directed by the Engineer in charge. 100mm PN 16
